Selamectin + Sarolaner (Revolution Plus)

Revolution Plus represents an advancement in feline parasite prevention, combining two powerful active ingredients—selamectin and sarolaner—to provide comprehensive protection against a wide range of internal and external parasites. This innovative topical medication addresses a significant gap in feline parasite control by adding robust tick protection to the already extensive coverage provided by the original Revolution formulation. Since its FDA approval for veterinary use, Revolution Plus has become a preferred choice for veterinarians seeking to provide their feline patients with the most complete single-product parasite prevention available. The combination formulation is particularly valuable for cats living in areas where tick-borne diseases are prevalent or for those with outdoor access who face exposure to multiple parasite types.

The dual mechanism of action in Revolution Plus allows it to target parasites through two distinct pathways. Selamectin, a macrocyclic lactone, works by binding to glutamate-gated chloride channels in invertebrate nerve and muscle cells, causing paralysis and death of susceptible parasites including fleas, heartworm larvae, ear mites, and certain intestinal worms. Sarolaner, an isoxazoline compound, targets gamma-aminobutyric acid and glutamate-gated chloride channels in arthropods, providing potent activity against ticks and additional flea-killing efficacy. This complementary approach ensures that parasites are attacked through multiple mechanisms, enhancing overall effectiveness and providing rapid parasite knockdown. Once applied topically, both ingredients are absorbed systemically, distributing throughout the body to provide comprehensive protection.

Revolution Plus is available exclusively as a topical spot-on solution in single-dose applicator tubes, color-coded by weight range for cats and kittens eight weeks of age and older weighing at least 2.8 pounds. The product is applied once monthly to the skin at the base of the neck, where it is absorbed and distributed systemically. Application is quick and convenient, typically requiring less than a minute, making it an attractive option for cat owners compared to multiple single-purpose products or oral medications. The formulation dries quickly after application, minimizing the potential for transfer to other pets or household surfaces. Most cats accept the application well, though some may experience temporary behavioral changes immediately after application due to the sensation of the liquid on their skin.

The safety profile of Revolution Plus in cats is well-established through extensive clinical trials and post-market surveillance. The product has been shown to be safe for kittens as young as eight weeks, for breeding cats, and for cats in various health states when used according to label directions. The addition of sarolaner to the formulation has not significantly increased the adverse effect profile compared to selamectin alone, though owners should remain vigilant for any unusual reactions. Veterinary supervision is essential when initiating any parasite prevention program, and accurate dosing based on current body weight helps ensure both efficacy and safety. Regular monthly application throughout the year provides optimal protection against the spectrum of parasites that Revolution Plus targets.

Revolution Plus carries FDA approval for the prevention and treatment of flea infestations (Ctenocephalides felis), providing rapid flea kill and sustained prevention when applied monthly. The combination of selamectin and sarolaner delivers enhanced flea efficacy compared to either ingredient alone, with studies demonstrating greater than 98 percent effectiveness against adult fleas within 12 hours of application and continued protection throughout the month. Beyond killing adult fleas, the product prevents flea eggs from hatching, helping to break the flea life cycle in the home environment. This comprehensive flea control is essential for cats with flea allergy dermatitis, multi-pet households struggling with flea infestations, and any cat owner seeking reliable flea prevention.

The addition of sarolaner to Revolution Plus provides significant tick protection that was not available in the original Revolution formulation. The product is approved for the treatment and control of black-legged ticks (Ixodes scapularis), Gulf Coast ticks (Amblyomma maculatum), and American dog ticks (Dermacentor variabilis) for one month following application. This tick coverage is increasingly important as tick populations expand geographically and tick-borne diseases become more prevalent. While cats may be less commonly affected by some tick-borne diseases than dogs, tick infestations cause discomfort, can lead to skin irritation and secondary infections, and pose a potential risk for disease transmission to both cats and household members.

Heartworm prevention remains a critical indication for Revolution Plus, with selamectin providing protection against infection with Dirofilaria immitis when administered monthly. Heartworm disease in cats can cause severe respiratory disease and potentially sudden death, and there is no approved treatment for feline heartworm infection, making prevention essential. The medication kills immature heartworm larvae transmitted by infected mosquitoes, preventing them from developing into adult worms that cause clinical disease. Year-round administration is recommended in most regions to ensure continuous protection, as mosquito activity can occur unpredictably and even predominantly indoor cats can be bitten by mosquitoes that enter the home.

Revolution Plus effectively treats and controls ear mite infestations (Otodectes cynotis), one of the most common parasitic conditions affecting cats, particularly kittens and those with outdoor access. A single application typically eliminates ear mite infestations, though severe cases may benefit from a follow-up dose. The systemic distribution of the medication reaches mites within the ear canal without requiring direct ear application, making treatment more convenient and less stressful than traditional ear medications. Additionally, the product provides treatment and control of roundworm (Toxocara cati) and hookworm (Ancylostoma tubaeforme) infections, common intestinal parasites in cats that can cause gastrointestinal symptoms and, in the case of certain hookworms, pose zoonotic risk to humans.

Veterinarians select Revolution Plus when comprehensive, single-product parasite coverage is desired, particularly for cats at risk of tick exposure. The product is especially well-suited for outdoor cats, indoor-outdoor cats, cats in multi-pet households that include dogs who may bring ticks into the home, and cats living in regions endemic for tick-borne diseases. The convenience of addressing fleas, ticks, heartworms, ear mites, and intestinal parasites with a single monthly application simplifies compliance and ensures that cats receive consistent, complete protection. Cost-benefit analysis, regional parasite prevalence, and individual cat risk factors all influence product selection, and veterinarians can help cat owners determine whether Revolution Plus represents the most appropriate choice for their specific situation.

Revolution Plus dosing follows a weight-based protocol using pre-measured single-dose applicator tubes designed to deliver the appropriate amount of both selamectin and sarolaner for the cat's weight range. The product delivers a minimum dose of 6 mg/kg selamectin and 1 mg/kg sarolaner when applied according to label directions. Three tube sizes are available for cats, color-coded for weight ranges: one for cats 2.8 to 5.5 pounds, one for cats 5.6 to 11 pounds, and one for cats 11.1 to 22 pounds. Cats weighing more than 22 pounds should receive the appropriate combination of tubes as directed by their veterinarian. Accurate weighing before each monthly application ensures proper dosing and optimal efficacy.

The recommended dosing schedule for Revolution Plus is once monthly, year-round, for comprehensive parasite prevention. This consistent monthly application maintains therapeutic levels of both active ingredients, providing continuous protection against fleas, ticks, heartworms, and other target parasites. For heartworm prevention specifically, uninterrupted monthly dosing is critical, as gaps in coverage may allow heartworm larvae to develop into adult worms. Flea and tick control also benefit from regular monthly application, as consistent treatment prevents reinfestation and maintains the cat's parasite-free status. Some veterinarians may recommend specific timing based on regional parasite activity, though year-round prevention eliminates concerns about seasonal variations.

Treatment duration with Revolution Plus depends on ongoing risk assessment and lifestyle factors but typically continues indefinitely for cats at risk of parasite exposure. Indoor cats in heartworm-endemic areas should receive year-round prevention regardless of perceived mosquito exposure risk. Cats with outdoor access or those living in tick-endemic regions benefit from continuous monthly application to maintain consistent protection. When treating existing ear mite infestations, a single dose is usually curative, though monthly preventive applications should continue thereafter. For intestinal parasites, monthly application provides ongoing control, though cats with heavy initial burdens may require additional targeted deworming as directed by their veterinarian.

Application of Revolution Plus follows a straightforward process that most cat owners can perform at home. Select a time when your cat is calm, and enlist help if needed to keep the cat still. Part the hair at the base of the skull in front of the shoulder blades until the skin is visible—this location prevents the cat from grooming off the product. Place the applicator tip directly against the skin and squeeze the tube firmly to expel the entire contents onto the skin in one spot. Do not apply to hair or to broken or irritated skin. Avoid rubbing or massaging the product into the skin. The application site may appear wet initially but typically dries within a few hours. Keep treated cats separated from other pets and children until the product is completely dry.

When a dose of Revolution Plus is missed, apply the product as soon as you remember and resume the regular monthly schedule from that point. Do not apply extra product to compensate for missed doses. If a significant gap has occurred, particularly longer than six weeks, contact your veterinarian for guidance—they may recommend heartworm testing before resuming prevention in regions where heartworm is prevalent. Setting up monthly reminders through phone apps, calendar alerts, or veterinary clinic reminder programs helps maintain consistent application schedules. Many veterinary practices offer automated reminder services that alert owners when their cat's next dose is due.

Completing the recommended course of treatment means maintaining continuous monthly applications throughout the cat's life for optimal parasite prevention. Stopping Revolution Plus prematurely or using it only seasonally may leave your cat vulnerable to flea infestations, tick attachment, heartworm infection, and intestinal parasites. The consequences of lapses in prevention can range from uncomfortable skin conditions to life-threatening heartworm disease. If cost is a concern, discuss this with your veterinarian, who may suggest alternative prevention strategies or help prioritize which parasites pose the greatest risk to your individual cat. Never discontinue or reduce parasite prevention frequency without veterinary guidance.

Revolution Plus demonstrates an excellent safety profile in cats based on extensive clinical trials and ongoing post-market surveillance. The vast majority of cats tolerate the product well with no adverse reactions, even with long-term monthly use over years. The addition of sarolaner to selamectin has not substantially altered the overall safety profile of the original Revolution formulation. Both active ingredients have been extensively studied in cats individually and in combination, and their complementary mechanisms of action do not create unexpected synergistic toxicity. However, as with any medication, individual cats may experience side effects, and owner awareness enables prompt recognition and appropriate response.

Local reactions at the application site represent the most commonly reported side effects with Revolution Plus. Some cats may experience temporary hair loss, skin irritation, or redness at the spot where the product was applied, typically resolving within a few days to weeks without treatment. The application site may appear oily, wet, or clumped immediately after application, which is a normal cosmetic effect that resolves as the product dries and is distributed. Occasionally, cats may scratch or rub at the application site due to the sensation of the liquid, but this behavior usually subsides quickly. These local effects do not typically require discontinuation of treatment unless they persist, worsen, or spread beyond the application site.

Gastrointestinal symptoms including vomiting, diarrhea, decreased appetite, and hypersalivation have been reported in some cats following Revolution Plus application. These digestive disturbances are generally mild and transient, resolving within 24 to 48 hours without intervention. Cats that groom the application site before it has dried may be more likely to experience gastrointestinal effects due to oral ingestion of the product. Applying Revolution Plus to the base of the skull where cats cannot reach and separating treated cats from other pets until dry helps minimize ingestion risk. If gastrointestinal symptoms are severe or persist beyond 48 hours, veterinary consultation is recommended.

Isoxazoline class drugs, including sarolaner, have been associated with neurological adverse events in dogs and cats, though such events appear to be uncommon. Reported signs in cats may include tremors, ataxia (incoordination), and seizures, though these events are rare and most cats tolerate sarolaner-containing products without neurological effects. Cats with a history of seizures or other neurological conditions may warrant additional consideration before using Revolution Plus, and owners should discuss their cat's medical history thoroughly with their veterinarian. If neurological symptoms develop following application, immediate veterinary attention is warranted, and the product packaging should be brought to the appointment for reference.

Serious allergic reactions to Revolution Plus are rare but require immediate veterinary attention if they occur. Signs of a severe allergic response may include facial swelling, hives or widespread skin reactions, difficulty breathing, and collapse. Any cat showing signs of a severe reaction should receive emergency veterinary care immediately. Lethargy lasting more than 24 to 48 hours after application, persistent or severe vomiting, behavioral changes, or any other concerning symptoms should prompt consultation with your veterinarian. Documenting when the product was applied and what symptoms were observed helps veterinary staff assess the situation accurately. Most adverse reactions, when they occur, are mild and self-limiting, and the benefits of comprehensive parasite prevention generally outweigh the low risk of adverse effects for most cats.

Revolution Plus should not be used in cats with known hypersensitivity or allergic reactions to selamectin, sarolaner, or any of the inactive ingredients in the formulation. Cats that have previously experienced adverse reactions to Revolution, Revolution Plus, or other products containing these active ingredients should not receive subsequent doses without careful veterinary evaluation. Cross-reactivity may occur between sarolaner and other isoxazoline compounds such as fluralaner and afoxolaner, so cats with histories of reactions to any isoxazoline product should use Revolution Plus with caution. Similarly, cats that have reacted to other macrocyclic lactones such as ivermectin or milbemycin may have increased risk of reacting to the selamectin component. Complete disclosure of all previous adverse drug reactions to your veterinarian enables safe prescribing decisions.

Cats with a history of seizure disorders or other neurological conditions require careful consideration before using Revolution Plus or other isoxazoline-containing products. While neurological adverse events are uncommon, the isoxazoline class carries warnings regarding potential neurological effects. Veterinarians may recommend alternative parasite prevention products for cats with epilepsy or other seizure disorders, or they may determine that the benefits of comprehensive parasite prevention outweigh the risks in specific cases. This decision should be made collaboratively between the veterinarian and cat owner based on the individual cat's medical history, the severity and frequency of neurological episodes, and the parasite risks in the cat's environment.

Revolution Plus is approved for use in kittens eight weeks of age and older weighing at least 2.8 pounds. The product should not be administered to younger kittens or those below the minimum weight threshold, as safety has not been established in these populations. Studies have demonstrated safety in breeding, pregnant, and lactating cats when used at recommended doses, though as with any medication, veterinary consultation is advisable before treating cats in these reproductive states. Very small or debilitated cats may be at increased risk for adverse effects, and accurate weighing is particularly important in these patients to avoid overdosing relative to body mass.

Cats with severe hepatic or renal impairment may require special consideration before using Revolution Plus, as both the liver and kidneys play roles in drug metabolism and elimination. While clinical studies have not revealed significant concerns in cats with mild to moderate organ dysfunction, severely compromised organ function could theoretically alter drug handling. Cats with known liver or kidney disease should have their overall health status evaluated before starting any new medication. Your veterinarian can assess whether Revolution Plus is appropriate or whether alternative parasite prevention approaches might be safer for cats with significant organ disease. Complete health history disclosure, including all current medications and supplements, allows your veterinarian to make fully informed prescribing decisions.

Providing your veterinarian with a comprehensive list of all medications, supplements, and topical products your cat receives is crucial before starting Revolution Plus. The combination of two active ingredients increases the theoretical potential for drug interactions compared to single-agent products, making thorough medication history even more important. This disclosure should include prescription medications, over-the-counter products, herbal or natural supplements, and other topical treatments including flea collars, sprays, or spot-on products. Potential interactions may reduce the efficacy of Revolution Plus or other medications, increase the risk of adverse effects, or cause unexpected toxicities.

Concurrent use of Revolution Plus with other topical antiparasitic products is generally not recommended unless specifically directed by a veterinarian. Applying multiple spot-on treatments may overwhelm skin absorption capacity, alter systemic drug levels unpredictably, or increase the risk of local and systemic adverse effects. If additional parasite coverage is needed beyond what Revolution Plus provides, your veterinarian will recommend appropriate products and timing to minimize interaction potential. Similarly, flea collars or other sustained-release parasite products should not typically be combined with Revolution Plus without veterinary guidance. Bathing and shampooing should be avoided for at least 24 hours before and two hours after Revolution Plus application to ensure optimal absorption.

Drug interactions with oral medications have not been extensively documented for Revolution Plus specifically, but theoretical considerations apply. Both selamectin and sarolaner undergo hepatic metabolism, so drugs that significantly affect liver enzyme activity could theoretically alter their processing. Cats receiving medications known to affect cytochrome P450 enzymes or other metabolic pathways should be monitored for any changes in response to Revolution Plus or their other medications. Isoxazolines may interact with other compounds that affect GABA-gated chloride channels, though clinical significance in cats is not well established. When in doubt, conservative monitoring and awareness of potential interactions provide the safest approach.

Monitoring for drug interactions involves observing your cat for expected efficacy and unexpected adverse effects following Revolution Plus application. Signs that an interaction may be occurring include reduced parasite control despite consistent application, increased or unusual side effects, or changes in the cat's response to other medications. Report any concerns to your veterinarian promptly, including new symptoms that develop after starting Revolution Plus or changes in the effectiveness of the cat's other medications. Regular veterinary check-ups provide opportunities to assess overall drug regimen safety and efficacy. Your veterinarian may recommend periodic laboratory monitoring for cats receiving multiple medications to ensure that all drugs are being handled appropriately by the body.

Standard precautions for Revolution Plus use begin with accurate body weight determination before each monthly application. The weight-based dosing system requires current weight information to select the appropriate product strength—using an undersized dose reduces efficacy against parasites, while significant overdosing could increase adverse effect risk. Weigh your cat on a reliable scale monthly, particularly for growing kittens or cats whose weight fluctuates. Follow application instructions precisely, applying the product to intact skin at the recommended site and ensuring the entire tube contents are delivered. Monitoring your cat for the first few hours after application helps identify any immediate adverse reactions that might require attention.

While specific breed-related sensitivities to Revolution Plus have not been documented in cats, individual variation in drug response can occur regardless of breed. Some cats may be more sensitive to medications due to genetic variations in drug metabolism that do not follow strict breed lines. If you have concerns about your particular cat's ability to tolerate medications based on past experiences, discuss this with your veterinarian before starting Revolution Plus. Breeds with known predispositions to liver or kidney disease may warrant additional monitoring, though this relates more to general health management than to Revolution Plus specifically. Your veterinarian can advise on appropriate monitoring based on your cat's breed and individual health status.

Environmental and handling precautions protect both humans and animals in the household. Keep Revolution Plus away from children and store it securely until use. Avoid direct skin contact with the product when applying—if contact occurs, wash the area with soap and water. Eye contact requires immediate flushing with water and medical consultation if irritation persists. Do not smoke, eat, or drink while handling the product. In multi-pet households, keep treated cats separated from other animals, particularly dogs and other cats, until the application site is completely dry to prevent cross-grooming. The cat formulation should only be used on cats—do not apply to dogs or other species.

During treatment, monitor your cat for both efficacy and adverse effects. Effective treatment should result in reduced scratching and elimination of visible fleas within 24 to 48 hours, improvement in ear mite symptoms within one to two weeks, and absence of tick attachment. Signs of potential toxicity to watch for include excessive salivation, tremors, incoordination, seizures, persistent vomiting, severe lethargy, or behavioral changes. Contact your veterinarian promptly if concerning symptoms develop. Regular annual or semi-annual veterinary examinations allow assessment of parasite prevention program effectiveness and overall health monitoring.

Special populations require additional consideration when using Revolution Plus. Geriatric cats may have age-related changes in liver and kidney function affecting drug metabolism, though most senior cats tolerate the product well. Very young kittens must meet the minimum age and weight requirements. Cats with pre-existing seizure disorders warrant careful benefit-risk assessment before using isoxazoline-containing products. Immunocompromised cats, including those with FIV or FeLV infections, particularly benefit from consistent parasite prevention due to their increased vulnerability to parasite-related disease. Cats with chronic illnesses such as diabetes, hyperthyroidism, or heart disease can generally receive Revolution Plus safely, but coordination with their overall treatment plan ensures comprehensive care. Discuss your cat's complete health history with your veterinarian to optimize the parasite prevention approach.

Revolution Plus should be stored at controlled room temperature between 68°F and 77°F (20°C to 25°C), with excursions permitted between 59°F and 86°F (15°C to 30°C). Keep the product in a dry location away from direct sunlight, heat sources, and moisture. Refrigeration is not required and freezing should be avoided. Store the applicator tubes in their original packaging until ready for use, as this provides protection from light exposure and physical damage to the tubes. The sealed packaging maintains product integrity and prevents leakage during storage. Keep Revolution Plus in a secure location inaccessible to children and pets to prevent accidental exposure or ingestion.

The product packaging includes important information including lot numbers and expiration dates that should be verified before each use. Do not use Revolution Plus past the expiration date printed on the package, as efficacy cannot be guaranteed and degraded products may pose safety risks. Inspect applicator tubes before use—do not use tubes that appear damaged, leaking, or discolored. The solution should be clear to slightly yellow; cloudy solution or visible particles indicate potential degradation. Once opened, the entire contents of a tube should be applied immediately, as the product is not designed for partial application or storage after opening. Unused portions should be disposed of properly rather than saved for later use.

Safe handling and disposal practices protect household members and the environment. Wash hands thoroughly with soap and water after applying Revolution Plus to your cat. Avoid contact between the product and your skin, eyes, and mouth. If skin contact occurs, wash the affected area immediately. Eye contact requires thorough rinsing with water—seek medical attention if irritation persists. Used applicator tubes should be disposed of in household trash, not recycling bins, and should be kept away from water sources to prevent environmental contamination. Many communities have pharmaceutical take-back programs that accept veterinary products, representing the most environmentally responsible disposal option. Contact your local waste management authority or veterinary clinic for information about take-back programs in your area.

Revolution Plus demonstrates broad tolerability across cat breeds, with no documented breed-specific contraindications or significantly elevated adverse effect risks in particular breeds. The clinical trials supporting FDA approval included cats of various breeds, and post-market surveillance has not identified breed-related patterns of adverse reactions. This extensive safety data across diverse feline populations makes Revolution Plus a versatile choice for parasite prevention regardless of whether your cat is a domestic shorthair, longhair, or purebred. However, individual variation exists within all breeds, and some cats may be more sensitive to medications due to factors that are not strictly breed-associated.

Certain breed-related health predispositions warrant consideration when prescribing any medication, including Revolution Plus. Persian and Himalayan cats have increased prevalence of polycystic kidney disease, while some lines of Abyssinians and other breeds may be predisposed to hepatic amyloidosis or other liver conditions. Maine Coon cats have elevated rates of hypertrophic cardiomyopathy. These breed-associated conditions do not contraindicate Revolution Plus use but may influence overall health monitoring approaches. Cats with known organ dysfunction should be evaluated individually to determine appropriate parasite prevention, and coordination between parasite prevention and management of underlying conditions ensures comprehensive care.

Size variations among cat breeds influence product selection within the Revolution Plus weight-based dosing system. Larger breeds including Maine Coons, Ragdolls, Norwegian Forest Cats, and British Shorthairs may fall into higher weight categories requiring larger tube sizes. Smaller breeds such as Singapura, Devon Rex, and Cornish Rex typically require smaller doses. Accurate weighing before each monthly application ensures appropriate dosing regardless of breed or size. Cats at the upper threshold of a weight category should be discussed with your veterinarian to determine whether the current formulation remains adequate or whether adjusting to the next strength is appropriate.

Age-related considerations apply across all breeds equally. Kittens of any breed may begin receiving Revolution Plus at eight weeks of age when weighing at least 2.8 pounds. Early parasite prevention is particularly valuable for kittens, who are more susceptible to the health impacts of parasitic infections. Senior cats of all breeds may experience age-related changes in organ function that could theoretically affect drug handling, though Revolution Plus maintains an excellent safety record in geriatric cats. Your veterinarian can recommend appropriate monitoring for older cats as part of comprehensive senior wellness care. The benefits of continued parasite prevention typically outweigh theoretical risks in healthy senior cats, though individualized assessment ensures the best approach for each patient.

Several alternative broad-spectrum antiparasitic products may be considered when Revolution Plus is not appropriate or when different coverage is desired. The original Revolution (selamectin alone) provides similar coverage without the enhanced tick protection of Revolution Plus, suitable for cats without significant tick exposure risk. Bravecto Plus combines fluralaner and moxidectin, offering extended flea and tick protection lasting up to two months along with heartworm prevention. Advantage Multi pairs imidacloprid with moxidectin for flea control and heartworm prevention. Each product has distinct active ingredients, spectrums of activity, and application intervals, so selection depends on specific parasite concerns, regional risk factors, and individual cat considerations.

For cats requiring targeted parasite protection rather than broad-spectrum coverage, single-purpose products remain available. Heartgard contains ivermectin for heartworm prevention alone, while Interceptor provides milbemycin oxime for heartworm and intestinal parasite control. Flea-only products such as Advantage (imidacloprid) or Capstar (nitenpyram) address flea infestations without affecting other parasites. Tick-specific products may be appropriate in certain situations, though most tick products for cats also include flea coverage. Veterinarians can help determine whether comprehensive products like Revolution Plus or targeted combinations of single-purpose products best meet an individual cat's needs based on lifestyle, geographic location, and cost considerations.

Complementary approaches enhance the effectiveness of any antiparasitic program. Environmental flea control through regular vacuuming, washing pet bedding, and treating the home environment helps reduce flea populations and reinfestation pressure. Tick prevention includes habitat modification such as keeping grass trimmed and removing leaf litter where ticks thrive. Regular grooming and coat inspection help identify parasites early. Probiotics may support digestive health in cats receiving medications, though direct interactions with Revolution Plus are not documented. Never substitute parasite prevention products without veterinary guidance, as each product has specific indications, safety profiles, and appropriate use parameters. Your veterinarian can design a comprehensive parasite management program tailored to your cat's individual circumstances and risk factors.
