American Curl (Longhair) - Names & Recognition

The American Curl name directly describes the breed's most distinctive feature—the uniquely curved ears that curl backward—combined with its geographic origin in the United States. The breed was named when it gained formal recognition in the 1980s, with "curl" specifically referring to the ear shape that defines the breed. The name has remained consistent across all major cat registries including The International Cat Association (TICA), the Cat Fanciers' Association (CFA), and international organizations worldwide.

Within the breed, there are two coat length varieties: shorthaired and longhaired. Both varieties share identical breed standards aside from coat length and grooming requirements. The longhaired variety is sometimes specified as "American Curl Longhair" or "Longhair American Curl" to distinguish it from the shorthaired variety. However, both are considered the same breed—American Curl—with coat length being the only significant difference. Both varieties can appear in the same litter.

The breed is occasionally nicknamed "the cat with the smile in its ears" or "smiley cat" due to the curved ears that create the impression of a perpetual smile or happy expression. This whimsical nickname captures the breed's cheerful appearance and pleasant temperament. Some enthusiasts also call them "Peter Pan cats" because they retain kitten-like playfulness and curiosity throughout their lives, never seeming to fully grow up in personality.

No official alternate names exist for the breed, though casual abbreviations like "AC" or "Curl" are sometimes used in breeding circles and among owners for convenience. These shortened forms are widely understood but informal, not appearing in official registry documentation. The breed is always officially registered as "American Curl" regardless of coat length.

The American Curl is officially recognized by all major cat registries. TICA granted championship status in 1987, remarkably quickly after the breed's discovery in 1981. CFA followed with championship status in 1993. International registries including FIFe and others have also recognized the breed. This rapid and widespread recognition reflects the breed's distinctive appearance, appealing personality, and the responsible development program established by early breeders.

The breed's development included careful documentation of the genetic mutation causing the ear curl. Early breeders worked with geneticists to understand the inheritance pattern, discovering that the curl gene is dominant and affects ear cartilage development. This scientific approach helped establish the breed's legitimacy and health profile, contributing to swift registry acceptance.

Both shorthaired and longhaired American Curls are equally valued and shown in cat shows, with separate divisions for coat length in most registries. The longhaired variety often shows more dramatic presentation due to their flowing coats, though both varieties display the distinctive ear curl equally. Some people prefer one coat length over the other based on aesthetic preferences or grooming considerations, but both represent the breed equally.

American Curl (Longhair) Physical Description

The American Curl is a medium-sized cat with males typically weighing 7-10 pounds and females ranging from 5-8 pounds. They possess a moderate, well-balanced build that's neither cobby nor extremely elongated—described as semi-foreign in type. The body is rectangular in shape, moderately muscled and flexible, with length and height in proportion. The overall impression is of an elegant, well-proportioned cat that's neither fragile nor overly substantial.

The breed's most distinctive and defining feature is the ears—uniquely curved backward in a smooth arc ranging from 90 to 180 degrees. The curl should be firm and spring back when gently unfolded, demonstrating the strengthened cartilage that creates the curl. The ears are moderately large, wide at the base, and set upright on the head. The curl begins at the base and follows through to rounded tips that point toward the back of the skull or center of the back. The minimum curl for show cats is 90 degrees.

The degree of curl varies among individuals, with show standards requiring at least 90 degrees for exhibition. Pet-quality American Curls may have lesser curls or straight ears (if they inherit the non-curl gene from one parent). Kittens are born with straight ears that begin curling within 2-10 days after birth, continuing to develop until about 16 weeks of age when the curl stabilizes permanently. The curl development is gradual and fascinating to observe.

The longhaired American Curl features a semi-long coat that's soft, silky, and lies flat against the body. The coat has minimal undercoat, giving it a flowing, elegant appearance without excessive fluffiness. Hair is longer on the tail, creating a plumed effect. The ruff around the neck, ear furnishings, and britches on the hind legs show more pronounced coat length. The coat texture is fine and manageable, not prone to severe matting like some longhaired breeds.

American Curls come in virtually all colors and patterns, providing enormous variety. Common colors include white, black, blue, red, cream, brown, silver, and golden. Patterns include solid, tabby (classic, mackerel, spotted, ticked), tortoiseshell, calico, bicolor, pointed (like Siamese), smoke, and shaded varieties. The breed standard accepts all colors and patterns equally, with quality of type being more important than specific coloring. This variety ensures there's an American Curl to suit every aesthetic preference.

The head is a modified wedge—medium in length and width with rounded contours and gentle curves rather than flat planes. The profile shows a gentle rise from the bridge of the nose to the forehead, creating a slight curve rather than a straight line or extreme break. The muzzle is rounded without being square or pointed, and the chin is firm and well-developed. The overall facial structure creates a pleasant, open expression.

The eyes are moderately large, walnut-shaped, and set at a slight angle with the outer corner slightly higher than the inner corner. Eye color doesn't need to correspond to coat color except in pointed varieties (which require blue eyes). Common eye colors include gold, green, blue, and odd-eyed combinations. The eyes should be clear and bright, contributing to the breed's alert, friendly expression.

The legs are medium length in proportion to the body, moderately muscled with medium bone structure. The paws are medium and rounded. The tail is flexible, wide at the base, tapering to a rounded tip, and equal to body length. In longhaired American Curls, the tail is plumed and flowing, carried proudly and adding to their elegant appearance. The overall impression is of a balanced, well-proportioned cat with unique ears setting them apart from all other breeds.

Affection Level
American Curls are exceptionally affectionate cats that form deep bonds with their families. They love being near their owners and enjoy physical contact including lap sitting and cuddling. Their affection is genuine and consistent, making them wonderful companions for those seeking devoted, loving pets. They thrive on interaction and attention from their favorite people.
Friendliness
American Curls are remarkably friendly and outgoing with everyone, including strangers. They typically greet visitors with curiosity and confidence rather than hiding. Their sociable nature makes them excellent companions for households that entertain frequently. They genuinely enjoy meeting new people and adapt well to various social situations with minimal stress or fear.
Child-Friendly
American Curls are wonderful with children, showing remarkable patience and enthusiasm for gentle play. They tolerate the activity and noise of family life well and often form special bonds with children. Their playful nature matches well with energetic kids, and their gentle temperament makes them ideal family pets when children are taught respectful interaction.
Pet-Friendly
American Curls typically excel in multi-pet households, getting along well with other cats and cat-friendly dogs. Their adaptable, easygoing nature helps them integrate smoothly into various pet dynamics. They're neither overly dominant nor timid, coexisting peacefully with other animals. Early socialization ensures the best results with other pets.
Exercise Needs
American Curls have moderate exercise needs and enjoy regular play sessions. They're active and playful but not hyperactive, appreciating daily interactive play of 15-20 minutes. They enjoy climbing, jumping, and hunting games but balance activity with periods of rest. Their exercise needs are easily met through regular play in most households.
Playfulness
American Curls are highly playful cats that maintain kitten-like enthusiasm throughout their lives. They love interactive games, toys, and exploration. Their playful nature is entertaining and engaging, requiring owners who can provide regular stimulation. They often initiate play and create their own entertainment with household objects when interactive play isn't available.
Energy Level
American Curls possess moderate energy levels with balanced activity patterns. They enjoy bursts of playful energy followed by periods of calm rest and observation. This balanced energy makes them adaptable to various household environments. They're lively enough to be entertaining without being exhausting, fitting well into moderately active homes.
Intelligence
American Curls are intelligent cats that learn quickly and understand household routines effectively. They can learn tricks, solve puzzles, and figure out how to manipulate their environment. This intelligence requires mental stimulation through interactive play, puzzle toys, and training. They're observant and quickly adapt to their owners' patterns and household dynamics.
Tendency to Vocalize
American Curls are generally quiet cats that rarely vocalize excessively. When they do speak, their voices are soft and pleasant. They communicate more through body language and gentle sounds than constant meowing. This quiet nature makes them ideal for apartments or for people who prefer peaceful, unobtrusive companions.
Amount of Shedding
Longhaired American Curls shed moderately, with seasonal increases in spring and fall. Their silky coat produces noticeable amounts of loose hair that regular grooming easily manages. While not minimal shedders, their shedding is typical for longhaired breeds and controllable with consistent grooming routines. The lack of dense undercoat means less shedding than some longhaired breeds.

American Curl (Longhair) History & Origins

The American Curl breed began with a spontaneous genetic mutation discovered in June 1981 in Lakewood, California. Joe and Grace Ruga found two stray kittens—one longhaired black female with unusual backward-curling ears and a shorthaired companion—on their doorstep. They adopted the longhaired kitten, naming her Shulamith. The shorthaired kitten disappeared, but Shulamith became the foundation cat for the entire American Curl breed. Every American Curl alive today can trace their lineage back to Shulamith.

Shulamith's unique ears immediately attracted attention. In December 1981, she had her first litter of four kittens, two of which inherited the curled ears. This demonstrated that the ear curl was genetic and heritable. The Rugas shared kittens with cat enthusiast Nancy Kiester, who recognized the potential for a new breed. Kiester began a careful breeding program to establish and develop the American Curl while studying the genetic basis of the ear curl.

Early breeding programs quickly determined that the curl gene is autosomal dominant, meaning only one parent needs to carry the gene for some kittens to have curled ears. This differs from recessive traits requiring both parents to carry the gene. The dominant nature of the curl gene meant the trait could be reliably reproduced in breeding programs. Geneticists confirmed that the mutation affects ear cartilage development specifically, strengthening cartilage to hold the curved shape without causing other health issues.

Crucially, outcrossing to non-pedigreed domestic cats was not only allowed but encouraged in early breeding programs. This practice prevented inbreeding, maintained genetic diversity, and introduced variety in coat length, color, and pattern. Using domestic cats as outcrosses meant the American Curl developed with a broad genetic base, contributing to their overall health and vigor. Today, the breed maintains good genetic diversity compared to many other pedigreed breeds.

The breed gained recognition remarkably quickly. In 1983, breeders began showing American Curls at cat shows. The International Cat Association (TICA) accepted the breed for registration in 1985 and granted championship status in 1987—just six years after the breed's discovery. This rapid recognition was unprecedented and reflected the breed's distinctive appearance, appealing personality, and the thorough, scientifically-based development program established by early breeders.

The Cat Fanciers' Association (CFA) proved more cautious, accepting American Curls for registration in 1986 but not granting championship status until 1993. By then, the breed was well-established with careful breeding records, genetic documentation, and proven health profiles. Other international registries followed, with FIFe and other organizations recognizing the breed throughout the 1990s and 2000s.

Both shorthaired and longhaired varieties were recognized from the beginning, as both coat lengths appeared in early litters. The genetic basis for coat length was already well-understood—longhair is recessive, so breeding two shorthaired American Curls that both carry the longhair gene can produce longhaired kittens. Both varieties show the characteristic ear curl equally and share all other breed characteristics aside from coat length.

Early breeding programs established strict guidelines about ear care and breeding practices. Only American Curls with appropriately curled ears meeting breed standards are used in breeding programs, though straight-eared offspring (inheriting two copies of the non-curl gene) are valuable as pets and can be used in breeding programs as outcrosses. Breeding two curled-ear cats together is common and safe, unlike some dominant genetic traits that cause problems in homozygous form.

The breed attracted international attention, with breeding programs established in Europe, Canada, Japan, and other countries throughout the 1990s and 2000s. American Curls remain relatively uncommon compared to more established breeds but have devoted followings worldwide. Their unique appearance combined with wonderful personalities ensures continued interest among cat enthusiasts.

Modern American Curl breeding focuses on maintaining the distinctive ear curl while ensuring overall health and genetic diversity. Breeders continue to outcross to domestic cats occasionally to maintain genetic vigor, though most breeding now occurs between established American Curl lines. Health testing and careful record-keeping help maintain the breed's soundness while preserving the characteristics that make American Curls special.

The breed represents a successful example of developing a new breed from a spontaneous mutation through careful, ethical breeding practices. The American Curl's story demonstrates how responsible breeders can establish healthy, distinctive breeds by prioritizing genetic diversity, health testing, and scientific understanding of genetics. From one stray kitten in 1981 to an internationally recognized breed, the American Curl's rapid development and acceptance reflects both their appeal and the dedication of early breeders who established the breed on sound foundations.

American Curl (Longhair) Temperament & Personality

The American Curl temperament is characterized by playfulness, affection, and perpetual kitten-like enthusiasm. These cats are often described as never fully growing up in personality, maintaining curiosity, playfulness, and zest for life throughout their lives. This Peter Pan quality makes them endlessly entertaining companions that bring joy and laughter to their families. Their youthful spirit persists even into their senior years, with many elderly American Curls still engaging enthusiastically in play.

Affection is central to the American Curl personality. These cats form deep bonds with their families and want to be involved in all household activities. They're not typically lap cats that sit still for extended periods—instead, they prefer being near their owners, following them from room to room, and participating in whatever is happening. Their affection manifests through presence, gentle head bumps, and desire to be included rather than through constant cuddling, though many do enjoy lap time periodically.

The breed is notably people-oriented and social. American Curls typically greet strangers with curiosity and confidence rather than hiding. They're outgoing without being pushy, friendly without being demanding. This sociability makes them excellent companions for households that entertain frequently or have varied visitors. They adapt well to new people and situations when properly socialized, showing little fear or reservation in new circumstances.

Playfulness is pronounced and persistent throughout American Curl lives. They love interactive games with toys, particularly those engaging hunting instincts. Many enjoy fetch, bringing toys back for repeated throws. They're inventive players who create their own entertainment when interactive play isn't available, often with creative and amusing results. Their playful nature requires engaged owners willing to provide regular play sessions, though they're not as demanding or high-energy as some extremely active breeds.

Intelligence characterizes the breed. American Curls learn quickly, understand household routines, and can be trained to perform tricks or follow commands. Many learn to open doors or drawers, understand where things are kept, and figure out cause and effect. This intelligence requires mental stimulation through puzzle toys, interactive play, and training sessions. They respond well to positive reinforcement training and enjoy the mental challenge of learning new behaviors.

American Curls are generally quiet cats that rarely vocalize excessively. When they do speak, their voices are soft and pleasant. They communicate needs through gentle meows and body language rather than constant chattering. This quiet nature makes them suitable for apartments and for people who prefer peaceful companions. They're not silent—they'll express themselves when necessary—but they're not demanding or intrusive with their vocalizations.

The breed is notably adaptable and adjusts well to various living situations. They're comfortable in apartments or houses, with single people or large families, as only cats or in multi-pet households. This adaptability makes them versatile companions suitable for many different types of homes and lifestyles. They handle changes reasonably well when supported through transitions, though they appreciate routine and consistency like most cats.

American Curls typically get along well with children, other cats, and cat-friendly dogs. Their patient, gentle nature makes them tolerant of respectful interaction, and their playfulness appeals to active families. They're neither aggressive nor timid, coexisting peacefully with other animals when properly introduced. Their adaptable temperament helps them find their place in household hierarchies without significant conflict.

Curiosity drives much of American Curl behavior. They investigate new objects, explore their environment thoroughly, and take interest in household activities. They want to know what you're doing and often try to help—whether you're working on the computer, making the bed, or cooking dinner. This curiosity is endearing but means they can get into things if not supervised. Providing appropriate outlets for curiosity through environmental enrichment prevents boredom.

The breed demonstrates loyalty to their families without being clingy or possessive. They form strong bonds and show preference for their people, but they're not typically anxious or distressed by brief separations. They greet their owners enthusiastically when reunited but manage reasonable periods alone better than some extremely dependent breeds. They balance attachment with reasonable independence.

Overall, the American Curl temperament makes them ideal for families or individuals seeking playful, affectionate, interactive companions that truly become family members. They're suitable for first-time cat owners due to their adaptable, easygoing nature. They're not demanding or high-maintenance emotionally, but they do appreciate attention and interaction. For those wanting cats that bring joy, entertainment, and steady affection without being overwhelming, American Curls deliver perfectly.

Care Requirements

Caring for an American Curl involves meeting their physical, social, and mental needs while paying special attention to their unique ears. The most distinctive care requirement involves ear maintenance—the curled ears require careful handling and regular inspection to ensure they remain clean and healthy. Never force the ears to uncurl or straighten them, as this can damage the strengthened cartilage. Handle ears gently during grooming and examinations.

Physical exercise needs are moderate but important for maintaining the American Curl's health and happiness. These cats need daily interactive play sessions totaling 15-20 minutes or more, distributed throughout the day. Use toys that engage hunting instincts—feather wands, small prey toys, and interactive games. They enjoy climbing and jumping, so provide opportunities through cat trees and shelves. Without adequate exercise, they may become bored or gain weight.

Environmental enrichment should include vertical space for climbing and observation. Cat trees, wall-mounted shelves, and window perches allow American Curls to survey their territory from elevated positions. Puzzle feeders, food-dispensing toys, and rotating regular toys provide mental stimulation between interactive play sessions. Their intelligence and curiosity mean they appreciate variety and challenges that engage their minds.

American Curls are ideal indoor cats and should be kept exclusively indoors for their safety. Their friendly, trusting nature makes them vulnerable to dangers, their unique appearance makes them theft targets, and outdoor exposure increases disease and injury risks. Indoor living with controlled environment, safety from predators and traffic, and protection from diseases ensures the longest, healthiest life.

Litter box management follows standard guidelines—one box per cat plus one extra, scooped daily, cleaned thoroughly weekly. American Curls are typically fastidious and may refuse dirty boxes. Place boxes in quiet, accessible locations away from food and water. Most American Curls adapt readily to various litter types, though unscented clumping litter is generally preferred.

Grooming requirements for longhaired American Curls are moderate and manageable. Brush 2-3 times weekly with a metal comb or slicker brush to prevent matting and remove loose hair. Pay particular attention to areas prone to tangling: behind the ears, under the arms, in the britches, and the plumed tail. Their minimal undercoat means the coat is less prone to severe matting than some longhaired breeds, but consistent grooming prevents problems.

Ear care requires special attention due to the unique curl. Check ears weekly, looking inside for any dirt, wax buildup, or signs of infection. Clean the outer ear and accessible inner ear areas with veterinarian-approved ear cleaner and cotton balls—never insert anything into the ear canal. The curl can make it slightly more challenging to see deep into the ear, so be thorough but gentle during inspections. Any redness, excessive wax, odor, or head shaking warrants veterinary evaluation.

Regular veterinary care is essential. Schedule annual wellness examinations where your veterinarian can assess overall health, check the ears specifically, update vaccinations, and monitor for any concerns. American Curls are generally healthy with few breed-specific issues, but regular monitoring ensures any problems are caught early. Establish a relationship with a veterinarian familiar with the breed's unique ear structure.

Maintain current vaccinations appropriate for indoor cats based on your veterinarian's recommendations. Implement year-round parasite prevention even for strictly indoor cats. American Curls should be spayed or neutered unless part of responsible breeding programs. This prevents unwanted litters, reduces certain health risks, and often results in calmer, more content pets. Microchipping provides permanent identification.

Socialization and interaction are important for American Curls' wellbeing. While not as demanding as extremely social breeds, they appreciate regular attention and interaction with family members. They don't do well with extended isolation and benefit from having consistent companionship, whether human or animal. Their social nature means they're happiest in households where someone is home much of the time or where they have pet companions.

Training and mental stimulation enrich American Curl lives. These intelligent cats enjoy learning and respond well to clicker training, trick training, and interactive games. Teaching commands, practicing gentle handling of ears and body, and providing positive experiences creates confident, well-adjusted cats. Their intelligence and willingness to engage make training rewarding for both cat and owner.

Feeding & Nutrition

Feeding an American Curl properly supports their health, maintains their moderate build, and provides energy for their playful lifestyle. As cats with balanced, moderate physiques, they require high-quality, protein-rich diets to maintain muscle tone and overall health. Look for cat foods listing meat, poultry, or fish as primary ingredients, with protein content of at least 30-40% on a dry matter basis for adults.

Both dry and wet food can be part of a healthy diet. Wet food provides excellent moisture content (75-80%) supporting hydration and urinary tract health. Many American Curls prefer wet food due to its palatability and strong aroma. Dry food offers convenience and may help maintain dental health through mechanical cleaning. Many owners feed a combination—wet food for main meals and limited dry food for occasional snacking. Consult your veterinarian about the best approach for your individual cat.

Portion control is important for maintaining the American Curl's moderate build. These cats can gain weight if overfed or insufficiently exercised. Adult American Curls typically need 200-280 calories daily depending on size, age, and activity level. Follow feeding guidelines on your chosen food package, adjusting based on your cat's body condition. You should feel ribs easily without seeing them prominently, and cats should have visible waists when viewed from above.

Establish regular feeding schedules rather than free-feeding. Most adult American Curls do well with two to three meals daily, spaced evenly throughout the day. Scheduled feeding helps monitor appetite and quickly notice changes that might indicate health issues. It also provides structure that many cats find comforting and prevents overeating in cats without good self-regulation. Kittens require more frequent feeding—three to four small meals daily until about six months of age.

Interactive feeding methods work well for intelligent American Curls. Puzzle feeders and food-dispensing toys provide mental stimulation while slowing eating to prevent digestive upset and obesity. These tools engage their problem-solving abilities and provide enrichment during times when you're unavailable for play. Start with simple puzzles and gradually increase difficulty as your cat masters them.

Some American Curls may have food sensitivities or allergies, though this varies individually. Signs include vomiting, diarrhea, excessive scratching, skin irritation, or ear infections. If your cat exhibits these symptoms, consult your veterinarian. They may recommend elimination diets or novel protein sources to identify problematic ingredients. Common feline allergens include certain proteins, corn, wheat, soy, and dairy products.

Fresh, clean water must be available at all times. Many cats prefer running water, so consider providing cat water fountains to encourage adequate hydration. Proper hydration supports kidney health, helps regulate body temperature, and contributes to overall wellbeing. Change water daily and wash bowls regularly to prevent bacterial growth. Monitor water intake—significant changes can indicate health problems requiring veterinary attention.

Treats should comprise no more than 10% of daily caloric intake to prevent nutritional imbalances and weight gain. Use treats strategically for training and bonding, choosing healthy options like freeze-dried meat treats, small pieces of cooked chicken, or commercial cat treats designed for nutritional balance. Avoid human foods that are toxic to cats, including chocolate, onions, garlic, grapes, raisins, and products containing xylitol.

As your American Curl ages, dietary needs may change. Senior cats often benefit from foods formulated for mature cats that support joint health, maintain muscle mass despite decreased activity, and provide appropriate calorie levels. Cats with health conditions may require prescription diets. Work closely with your veterinarian to adjust your cat's diet throughout life stages, ensuring optimal nutrition for changing needs while maintaining the healthy weight characteristic of the breed.

American Curl (Longhair) Health & Lifespan

American Curls are generally healthy cats with good genetic diversity resulting from careful breeding practices including outcrossing to domestic cats. The breed doesn't suffer from concentrated genetic health issues affecting many pedigreed breeds. With proper care, American Curls typically live 12-16 years, with many individuals reaching their late teens. The ear mutation causing the curl is benign and doesn't affect overall health. Choosing kittens from responsible breeders who conduct health testing and avoid breeding practices that could compromise health significantly reduces risks of any issues.

Common Health Issues

  • Ear Issues and Infections: While the ear curl itself is benign, the unique ear structure can make cleaning slightly more challenging and may trap debris more easily than straight ears. Wax buildup, dirt accumulation, or inadequate cleaning can lead to ear infections. Regular inspection and cleaning prevent most problems. Signs of ear infections include redness, odor, excessive wax, head shaking, or scratching at ears. Prompt veterinary attention treats infections effectively before they become serious.
  • Narrow Ear Canals: Some American Curls may have narrower ear canals than average cats, potentially making them slightly more prone to buildup and infections. This anatomical variation isn't universal but occurs in some individuals. Regular veterinary ear examinations ensure any issues are identified early. Narrow canals require more vigilant cleaning and monitoring but don't typically cause significant problems with proper care.
  • Obesity: While not a genetic condition, obesity is a potential concern in American Curls if they're overfed or insufficiently exercised. Their moderate build means excess weight is noticeable and impacts health. Obesity increases risks of diabetes, joint problems, and other health issues. Prevention through portion control, regular exercise, and appropriate diet is crucial. Monitor body condition regularly and adjust feeding if weight gain occurs.
  • Dental Disease: Like all cats, American Curls can develop dental problems including gingivitis, periodontal disease, and tooth resorption. Poor dental health affects overall health and causes pain. Prevention through regular tooth brushing and professional cleanings is more effective than treating advanced disease. Establish dental care routines early and maintain them throughout life. Annual dental examinations identify problems requiring intervention.
  • Hypertrophic Cardiomyopathy (HCM): This is the most common heart disease in cats, though American Curls aren't particularly predisposed compared to other breeds. HCM causes heart muscle thickening that can lead to heart failure. Regular veterinary examinations including cardiac auscultation help detect heart murmurs suggesting problems. While not breed-specific, awareness and monitoring support early detection and management if it occurs.
  • Kidney Disease: Chronic kidney disease is common in aging cats across all breeds. While not specific to American Curls, it's a significant concern for senior cats. Signs include increased thirst and urination, weight loss, decreased appetite, and lethargy. Early detection through regular senior wellness bloodwork allows dietary management and supportive care that can slow progression. Maintaining good hydration throughout life supports kidney health.

Preventive Care & Health Monitoring

  • Ear Inspection and Cleaning: Check ears weekly for dirt, wax buildup, or signs of infection. Clean outer ears and accessible inner ear areas with veterinarian-approved ear cleaner and cotton balls. Handle ears gently, never forcing them to uncurl or inserting anything into the ear canal. Regular home care prevents most ear issues. Any concerning changes including redness, odor, excessive wax, or behavioral changes like head shaking warrant veterinary evaluation.
  • Regular Veterinary Examinations: Annual wellness visits for adults and twice-yearly exams for seniors (over 10 years) allow early detection of health issues when they're most treatable. These exams should include physical examination, weight and body condition assessment, ear examination, dental evaluation, and cardiac auscultation. Blood work and urinalysis help identify internal issues before symptoms appear. Establishing baseline health markers enables monitoring changes over time.
  • Dental Hygiene: Establish dental care routines including daily tooth brushing with cat-specific toothpaste and professional cleanings as recommended by your veterinarian. Begin dental care young to establish tolerance and good habits. Use cat-specific toothpaste and a soft brush or finger brush. Annual dental examinations identify problems early, and professional cleanings prevent progression to serious disease requiring extractions.
  • Weight Management: Monitor your American Curl's weight and body condition regularly, providing adequate exercise and adjusting food portions to maintain optimal weight. You should feel ribs easily without seeing them prominently, and your cat should have a visible waist when viewed from above. Regular play sessions keep them physically fit and mentally stimulated. Preventing obesity is easier than treating it and supports overall health throughout life.

American Curls' careful development with outcrossing to domestic cats has created fundamentally healthy cats without concentrated breed-specific health problems. The ear curl mutation is benign and doesn't cause health issues when ears are properly cared for. While they can develop health issues common to all cats, they lack the genetic problems affecting many pedigreed breeds. Choosing cats from responsible breeders, maintaining preventive care, paying special attention to ear health, and addressing concerns promptly provides the foundation for long, healthy, active lives filled with the playful joy that characterizes this breed.

Coat Color & Grooming

The longhaired American Curl features a semi-long coat that's soft, silky, and lies flat against the body, creating an elegant, flowing appearance. The coat has minimal undercoat, giving it a fine texture that's less prone to matting than many longhaired breeds. Hair is longest on the plumed tail, with moderate length on the ruff around the neck, ear furnishings, britches on the hind legs, and tufts between the toes. The body coat is semi-long, not extremely long, making grooming manageable.

American Curls come in virtually every color and pattern imaginable, providing enormous variety. Solid colors include white, black, blue, red, cream, chocolate, cinnamon, lavender, and fawn. Tabby patterns—classic (swirled), mackerel (striped), spotted, and ticked—appear in multiple color combinations. Tortoiseshell, calico, and bicolor patterns feature multiple colors in various distributions. Pointed patterns (like Siamese coloring), smoke, and shaded varieties are also accepted. All colors and patterns are equally valued in breed standards.

Eye color doesn't need to correspond to coat color except in pointed varieties (which require blue eyes). Common eye colors include gold, green, blue, hazel, and odd-eyed combinations (one blue, one gold or green). The wide variety of accepted colors and patterns means prospective owners can find American Curls matching virtually any aesthetic preference while maintaining the distinctive curled ears that define the breed.

The coat texture is one of the breed's appealing characteristics. The silky, fine texture feels luxurious and smooth to the touch. The minimal undercoat means the coat doesn't become excessively fluffy or develop the cottony texture some longhaired breeds display. Instead, it maintains a sleek, flowing appearance that enhances the cat's elegant lines. The coat lies relatively flat against the body rather than standing out dramatically.

Grooming requirements for longhaired American Curls are moderate and manageable. Brush 2-3 times weekly with a metal comb or slicker brush to prevent tangles and remove loose hair. Start at the head and work toward the tail, paying particular attention to areas prone to matting: behind the ears, under the arms, the britches, and the tail. The minimal undercoat means matting is less common than in breeds with dense undercoats, but consistent grooming prevents any problems.

Seasonal shedding occurs in spring and fall, with increased loose hair during these transitions. Increase brushing frequency to daily during heavy shedding periods to manage loose hair and reduce hairballs. Many American Curls enjoy grooming sessions when established as pleasant routines with gentle handling and positive reinforcement. Regular brushing also provides opportunity to check skin condition and bond with your cat.

Bathing is occasionally necessary, typically every 2-3 months or as needed when the coat becomes soiled or greasy. Use lukewarm water and gentle cat-specific shampoo, lathering thoroughly and rinsing completely to remove all residue. Pay special attention to keeping water out of the ears during bathing, as the curl can make them more susceptible to water retention. Dry thoroughly with towels, ensuring your cat is completely dry before allowing them to roam freely.

Ear grooming requires special attention. The curl creates more surface area where dirt and debris can accumulate, particularly in the crevices of the curl. Check ears weekly and clean gently with veterinarian-approved ear cleaner and cotton balls. Handle ears with care, never forcing them to straighten. Clean only what you can see and reach easily—never insert anything into the ear canal. The ear furnishings in longhaired varieties may need occasional trimming if they grow excessively long.

Nail trimming every 2-3 weeks maintains appropriate claw length and reduces scratching damage. Provide sturdy scratching posts or pads to satisfy natural scratching instincts while protecting furniture. Most American Curls accept nail trimming well when introduced gradually with positive reinforcement.

Dental care through daily tooth brushing or dental treats supports overall health. American Curls generally tolerate tooth brushing well when introduced gradually. Use cat-specific toothpaste and a soft brush or finger brush. The overall grooming routine for longhaired American Curls is moderate, requiring consistent attention but not excessive time. Their relatively easy-care coats combined with their unique ears create cats that are distinctive in appearance while remaining manageable in maintenance.

American Curls are outstanding family cats that excel with children. Their patient, playful nature makes them ideal companions for families with respectful kids. They tolerate the activity and noise of family life well and often form special bonds with children. Their playfulness matches children's energy levels, and they enjoy interactive games that naturally appeal to kids. Unlike more nervous breeds, American Curls embrace family dynamics and actively participate in household activities.

The breed's gentle temperament makes them remarkably tolerant of children's antics. They rarely display aggression even during enthusiastic play, preferring to retreat if interaction becomes too intense rather than scratching or biting. However, children should be taught appropriate interaction—particularly regarding the ears, which should never be pulled, forced to straighten, or handled roughly. Teaching children to treat the unique ears with respect and gentleness is essential.

Teaching children proper cat interaction creates positive relationships. Kids should learn to pet gently, recognize body language indicating the cat needs space, and understand that cats aren't toys to be carried constantly or dressed up against their will. Demonstrate gentle approaches and calm handling, supervise interactions with young children, and include children in feeding, grooming (under supervision), and play routines. When children participate appropriately in cat care, they develop responsibility and strengthen bonds.

American Curls are best suited to families with children of all ages, including young children, when supervision and teaching are provided. Their robust build and patient nature make them more tolerant than some delicate or nervous breeds. However, very young children still require constant supervision to prevent accidental harm to the cat's ears or body. Teaching children never to grab or pull the curled ears prevents injury and maintains trust.

Providing safe retreat spaces ensures the cat's comfort even in busy households. Cat trees, quiet rooms, or elevated perches give them places to rest when they want breaks from interaction. Teaching children to respect these boundaries helps everyone coexist happily. Most American Curls will eagerly return to family activities once they've had brief respite, as they genuinely enjoy being part of family life.

Regarding other pets, American Curls are exceptionally adaptable and integrate well into multi-pet households. They typically get along well with other cats when properly introduced, showing neither excessive dominance nor timidity. Their easygoing nature helps them coexist peacefully with other felines. When introducing cats, follow gradual protocols with scent swapping, visual barriers, and supervised meetings. American Curls often form close bonds with other cats, providing mutual companionship.

These cats also coexist happily with cat-friendly dogs, particularly when raised together from young ages. Their confident but gentle nature prevents them from being intimidated by dogs while avoiding aggressive interactions. Proper introductions involving controlled, supervised meetings help establish positive relationships. Many American Curl-dog pairs become close friends, sleeping together and seeking each other's company.

Ideal canine companions include friendly, gentle breeds or individuals that enjoy feline company without being pushy or aggressive. Dogs with strong prey drives or that play too roughly aren't suitable companions for any cat. Introduce dogs and cats gradually, ensuring the dog is genuinely cat-friendly and will respect the cat's boundaries. Some American Curls actively engage their canine companions in play, while others prefer peaceful coexistence.

Small pets such as birds, hamsters, rabbits, or fish may be at risk around American Curls despite their gentle temperament toward humans and larger pets. All cats retain hunting instincts that can trigger predatory behavior toward prey-sized animals. While individual cats vary in prey drive, never assume any cat will consistently ignore small animals. Small pets should always be housed in secure, escape-proof enclosures inaccessible to cats, and interactions should be closely supervised if allowed at all.

With proper introduction, supervision, and respect for individual personalities, American Curls thrive in diverse family situations. Their adaptable nature, playful temperament, and gentle disposition make them versatile companions suitable for various household compositions. They bring joy, entertainment, and devoted companionship to families who appreciate their unique combination of distinctive appearance, wonderful personality, and adaptable nature. Their tolerance, patience, and genuine enjoyment of family life make them ideal for households seeking fully integrated feline family members.
