Rex — Newborn & Baby Care

Rex rabbit kits are born completely helpless, arriving hairless, deaf, and with their eyes sealed shut. A typical Rex litter ranges from six to twelve kits, and their survival in the first day depends heavily on the doe's instincts and the keeper's attentiveness. The kits should be checked shortly after birth to confirm that all are alive, that the placenta has been cleared, and that the doe has pulled sufficient fur to line the nest box. Stillborn or underdeveloped kits should be gently removed so the doe can focus her energy on the viable young.

The nest box is the single most important element during the first twenty-four hours. It should be snug enough that the kits stay clustered together for shared warmth but large enough for the doe to enter and nurse comfortably. Rex does are generally good mothers, but first-time mothers may scatter kits outside the nest. If this happens, simply return the kits to the nest and add extra fur or clean straw to insulate them. Check that the doe nurses at least once within the first twelve hours by gently examining the kits' bellies, which should appear round and plump after a successful feeding.

Ambient temperature matters enormously at this stage. Newborn Rex kits cannot regulate their own body temperature, so the nesting area should be kept between 65 and 75 degrees Fahrenheit. In cooler climates or seasons, a supplemental heat source placed safely outside the nest box can help maintain warmth without overheating. Avoid placing heating elements where the doe might chew cords or where kits could come into direct contact with hot surfaces.

During this initial period, limit handling to welfare checks only. The doe may become stressed by excessive human presence around the nest, and stress can cause her to neglect or even harm the litter. Keep the environment quiet, dim, and free from other pets or sudden disturbances. Brief, calm inspections of the kits once or twice in the first day are sufficient to ensure everything is progressing normally.

Rex does typically nurse their kits only once or twice per day, usually during the early morning or late evening hours. This is entirely normal rabbit behavior and should not be mistaken for neglect. Each nursing session lasts only a few minutes, during which the kits consume a remarkably rich milk that sustains them until the next feeding. Rabbit milk is among the most calorie-dense of any mammal, containing high levels of fat and protein that support the rapid growth Rex kits undergo in their first weeks.

The most reliable way to determine whether kits are being fed is to check their bellies. Well-fed kits will have round, full stomachs and warm, plump skin. Underfed kits appear wrinkled, with sunken bellies, and may feel cool to the touch. If you suspect the doe is not nursing, try placing her in the nest box for a supervised session. Sometimes first-time mothers need gentle encouragement, and a calm, enclosed space can trigger the nursing instinct.

The doe herself requires increased nutrition during the nursing period. Provide unlimited timothy hay and a generous portion of high-quality pellets, along with fresh leafy greens and constant access to clean water. A nursing doe may consume two to three times her normal food intake. Inadequate maternal nutrition will directly affect milk production and kit survival, so do not restrict the doe's diet during this time.

Orphaned Rex kits present a significant challenge, as hand-rearing newborn rabbits has a low success rate. If fostering to another nursing doe is possible, this is by far the best option. When hand-rearing is the only choice, use a kitten milk replacer and feed with a small syringe, offering tiny amounts every few hours. Overfeeding and aspiration are the greatest risks, so proceed slowly and keep the kit upright during feeding. Consult a rabbit-savvy veterinarian for specific guidance on volumes and schedules appropriate to the kits' age and weight.

Rex kits develop rapidly compared to many other domestic animals. By the end of the first week, a fine layer of the breed's signature velvety fur begins to emerge across the body. This early coat is one of the first visible indicators that the kits are growing on schedule. Weight gain should be steady and measurable, with healthy kits roughly doubling their birth weight within the first seven days.

Around ten to twelve days of age, the kits' eyes begin to open. This is a major milestone that signals the beginning of their sensory engagement with the world. Shortly after the eyes open, the ear canals also become functional, and the kits start responding to sounds in their environment. Any kit whose eyes remain sealed beyond fourteen days should be examined by a veterinarian, as delayed opening can sometimes indicate infection or developmental issues.

By the third week, Rex kits become increasingly mobile and curious. They begin venturing out of the nest box to explore their surroundings and will start nibbling on hay and pellets alongside their mother. This early sampling of solid food is an important precursor to weaning, and fresh hay should always be available within reach of the nest. The kits will continue nursing during this period, but their dependence on milk gradually decreases as solid food intake increases.

Between four and six weeks, the kits become fully furred with a recognizable Rex coat texture and are increasingly independent. Their movements become coordinated, and social behaviors such as grooming, play-chasing, and establishing hierarchy within the litter become evident. This is the stage where individual personality traits begin to emerge, with some kits showing bold, exploratory tendencies while others remain more cautious and reserved.

Maintaining an appropriate environment is critical for Rex kit survival, particularly during the first two weeks before they develop a full coat. The nesting area should remain between 65 and 75 degrees Fahrenheit, with the nest box itself staying warmer due to the insulating layer of fur the doe pulls and the body heat generated by the huddled litter. In warm climates, overheating can be just as dangerous as cold, so ensure adequate ventilation while avoiding direct drafts on the nest.

The nest box should be constructed of untreated wood or sturdy cardboard and filled with clean straw or hay, topped with the doe's pulled fur. The box should have sides high enough to prevent kits from accidentally tumbling out but low enough for the doe to enter easily. As the kits grow and become more mobile around the third week, you may need to lower one side of the nest box or provide a ramp so they can come and go without injury.

Hygiene within the nest must be managed carefully. Soiled bedding should be replaced regularly to prevent the buildup of ammonia and bacteria, but avoid completely stripping the nest of the doe's fur, as her scent provides comfort and helps her identify her young. A partial bedding change every two to three days is generally sufficient, removing only the wettest material and adding fresh straw beneath the existing fur lining.

The broader housing environment should be free from loud noises, strong odors, and the presence of predator animals. Even indoor cats and dogs can cause significant stress to a nursing doe through scent alone. Keep the rabbit housing area in a quiet part of the home, and minimize foot traffic and disruptions during the first few weeks. A stressed doe is more likely to neglect her litter or exhibit aggressive behavior toward the kits.

Gentle handling of Rex kits can begin as early as a few days after birth, provided the doe is comfortable with human interaction. Rex rabbits are known for their calm and sociable temperament, and early positive experiences with humans help reinforce these traits in the next generation. Start with brief handling sessions of just a minute or two, warming your hands first and moving slowly to avoid startling the kits.

The doe's reaction to handling should guide your approach. A well-socialized mother who trusts her keeper will generally tolerate brief inspections of her kits without distress. If the doe shows signs of anxiety, such as thumping, lunging, or circling frantically, reduce the frequency and duration of handling until she becomes more comfortable. Rubbing your hands in the nest bedding before picking up kits can help mask unfamiliar scents that might alarm the mother.

As the kits' eyes open and they begin to explore outside the nest around three weeks of age, socialization opportunities expand naturally. Allow the kits to approach your hand on their own terms, offering gentle strokes along the back and sides. Avoid grabbing from above, as this mimics predator behavior and can frighten young rabbits. Instead, scoop kits up from below, supporting their hindquarters securely.

Exposure to normal household sounds and activities during this period helps produce well-adjusted adult rabbits. The hum of appliances, voices at conversational volume, and the movement of people through the room all contribute to a kit's growing understanding of its domestic environment. Rex rabbits that are socialized thoughtfully during their first weeks tend to grow into confident, handleable adults that bond readily with their owners.

A wellness check by a rabbit-experienced veterinarian is recommended within the first week after birth, particularly for first-time breeders or if any kits appear underweight or unresponsive. The veterinarian can assess the overall health of the litter, check the doe's condition, and provide guidance on any concerns specific to your situation. Early veterinary relationships also establish a baseline for the kits' ongoing care as they mature.

During daily home checks, look for signs that all kits are thriving. Healthy newborn Rex kits have warm, pink skin that becomes progressively furred over the first two weeks. Their bellies should be round after nursing, and they should respond to gentle touch with wriggling or squirming. Kits that feel cold, appear bluish, or remain limp when handled need immediate attention, as these are signs of hypothermia, inadequate feeding, or illness.

Common health concerns in newborn Rex rabbits include nest box eye, a condition where the eyes become infected before or shortly after opening, typically caused by unsanitary nest conditions. Keeping the nest clean and dry is the best prevention. If you notice swelling, discharge, or crusting around a kit's eyes, seek veterinary care promptly, as untreated infections can cause permanent damage.

As the kits approach weaning age, around six to eight weeks, a pre-weaning veterinary visit is advisable. This examination can identify any developmental issues, check for parasites, and establish a vaccination schedule if recommended for your region. Your veterinarian can also advise on the appropriate timing for weaning based on the individual development of each kit, as smaller or slower-developing kits may benefit from an extended nursing period.

Despite the best care, complications can arise with newborn Rex kits that require prompt attention. One of the most common emergencies is a kit found outside the nest box, which can quickly become hypothermic even in moderate room temperatures. If you find a cold kit, warm it gradually against your body or in your hands before returning it to the nest. Rapid warming methods such as hot water or heating pads set too high can cause burns or shock.

Refusal to nurse is a serious concern that can quickly become life-threatening for the entire litter. If the doe has not nursed within twenty-four hours of birth, or if the kits' bellies remain flat and wrinkled across multiple checks, intervention is necessary. Sometimes repositioning the doe over the kits in a small enclosed space can trigger nursing. If this fails, contact your veterinarian immediately for advice on supplemental feeding options.

Watch for any kit that falls significantly behind its littermates in size or development. While some variation within a litter is normal, a kit that is markedly smaller, less active, or not gaining weight may have an underlying health issue or may be consistently pushed away from nursing by stronger siblings. Rotating smaller kits to more favorable nursing positions or providing brief supplemental feedings can help, but persistent failure to thrive warrants veterinary evaluation.

Diarrhea, labored breathing, unusual discharge from the eyes or nose, and sudden lethargy are all red flags at any age but are particularly dangerous in neonatal kits whose immune systems are still developing. Do not attempt to diagnose or treat these symptoms at home with over-the-counter remedies. Newborn rabbits are extremely sensitive to medications, and inappropriate treatment can be more harmful than the original condition. Always consult a rabbit-savvy veterinarian when symptoms appear.
