Mini Rex — Newborn & Baby Care

Mini Rex kits are born hairless, deaf, and with their eyes sealed shut. A typical litter ranges from four to seven kits, each weighing roughly one to one and a half ounces at birth. The doe will usually kindle in the early morning hours, and within minutes she will clean each kit and consume the afterbirth. This is entirely normal behavior and serves as a natural hygiene mechanism for the nest.

During the first day of life, it is critical that every kit nurses at least once. The doe typically feeds her young only once or twice per day, usually under the cover of darkness or when the environment is quiet. After nursing she will leave the nest, which is also normal — wild rabbits do this to avoid attracting predators. Do not assume the doe has abandoned her litter simply because she is not sitting with them.

Check the nest box gently within the first twelve hours. Count the kits, confirm that all bellies appear round and full, and remove any stillborn kits or soiled nesting material. Avoid excessive handling at this stage, but brief, calm contact will not cause the doe to reject her young. Keep your hands clean and free of strong fragrances when touching the kits.

If a kit has been pulled from the nest accidentally — sometimes a kit will cling to the doe's teat and be dragged out — return it to the nest immediately. Kits cannot regulate their body temperature and will become hypothermic within minutes in a cool room. A chilled kit should be warmed slowly in your cupped hands or on a towel-wrapped warm water bottle before being placed back into the nest.

The doe's milk is the sole source of nutrition for Mini Rex kits during the first two to three weeks of life. Rabbit milk is among the richest of any mammal, extremely high in fat and protein, which allows the doe to nurse for only a few minutes once or twice daily while still providing everything her young need. A well-fed kit will have a visibly distended, rounded belly after each feeding.

Supporting the doe's nutrition is the most effective way to support her kits. She should have unlimited access to high-quality grass hay, a generous portion of pellets formulated for nursing does, and fresh water at all times. Lactation dramatically increases her caloric and hydration needs, so monitor her body condition and adjust feed quantities accordingly. Fresh leafy greens can also be offered, but introduce them gradually if they were not part of her diet before kindling.

If a kit appears consistently underweight — with a sunken belly and visible spine — it may not be competing successfully for a teat position. In larger litters, smaller or weaker kits can be rotated to nurse first by briefly removing the stronger kits. Supplemental feeding with a kitten milk replacer and a small syringe is a last resort and should be done only under guidance from a rabbit-savvy veterinarian, as aspiration is a serious risk.

By the end of the second week, kits will begin to nibble on hay and the doe's cecotropes, which helps seed their gut with the beneficial bacteria essential for proper digestion later in life. This transition is gradual and should not be rushed. The doe will naturally begin to reduce nursing frequency as the kits start consuming solid food.

Mini Rex kits develop rapidly in their first few weeks. By day three or four, a fine fuzz of fur begins to emerge across their bodies. The distinctive velvety rex coat texture becomes more apparent as the fur fills in over the following week. By ten to twelve days, the kits' eyes will open, revealing dark, alert eyes that begin to take in their surroundings.

At around two weeks of age, the kits' ears open and they start to respond to sound. Their movements become more coordinated, transitioning from the crawling and squirming of the first days to tentative hops around the nest box. By three weeks they are actively exploring, climbing over the edges of the nest box, and interacting with their littermates through play.

Weighing the kits daily during the first two weeks, and then every two to three days thereafter, is an excellent way to track healthy development. A healthy Mini Rex kit should roughly double its birth weight within the first week and continue to gain steadily. Kits that plateau or lose weight need immediate attention, as this can indicate insufficient milk supply, illness, or competition from larger littermates.

Between three and four weeks, kits begin eating solid food in earnest — primarily hay and small amounts of pellets. Their digestive systems are still developing, so only foods the doe is already eating should be available. Novel foods should not be introduced during this fragile period.

Thermoregulation is the most immediate survival challenge for newborn Mini Rex kits. Born without fur, they are entirely dependent on the insulation of the nest and the warmth of their littermates to maintain body temperature. The doe pulls fur from her dewlap and sides to line the nest, creating a warm, insulated cocoon that can maintain temperatures significantly higher than the surrounding air.

The room where the nest box is kept should be maintained between 60 and 75 degrees Fahrenheit. Drafts are especially dangerous, as even a moderate air current can rapidly cool a nest of newborns. Position the cage or enclosure away from windows, exterior doors, and air conditioning vents. In colder climates or seasons, supplemental ambient heating for the room may be necessary, but never direct heat sources like heat lamps pointed at the nest, as these create burn and fire hazards.

The nest box itself should be appropriately sized — large enough for the doe to turn around in but small enough that the kits stay clustered together for warmth. A solid-bottomed box with sides about six inches high works well. Line it with soft hay first, then place the doe's pulled fur on top. If the doe has not pulled sufficient fur, you can gently pluck a small amount from her dewlap to supplement the lining.

As the kits grow fur and begin thermoregulating on their own around ten to fourteen days, the need for intensive nest insulation decreases. However, continue to monitor the nest for dampness or soiling, and replace bedding as needed. A damp nest can lead to hypothermia even in furred kits.

Gentle handling from a young age is one of the best things you can do to raise well-adjusted, people-friendly Mini Rex rabbits. Despite old myths to the contrary, handling newborn kits does not cause the doe to abandon them. Begin with brief daily health checks starting on day one, and as the kits grow and open their eyes, gradually increase the amount of calm, positive handling.

From around two weeks of age, pick each kit up for a minute or two daily. Support the body fully, keeping the kit close to your chest or lap. Speak softly and move slowly. The goal is to teach the kit that human hands are safe and that being held is a normal part of life. Kits that are handled regularly from this age are markedly calmer and more sociable as adults.

Once the kits are mobile and exploring outside the nest box at three to four weeks, allow them supervised time in a safe, enclosed area where they can experience different textures, gentle sounds, and household activity. Exposure to the normal rhythms of a home — footsteps, conversation, kitchen sounds — during this sensitive developmental window builds confidence and reduces startle responses later.

Introduce the kits to other calm household members gradually. Children should be seated on the floor and supervised closely, with the kit placed in their lap rather than held in the air. These early positive experiences form the foundation of the Mini Rex's famously friendly temperament.

A wellness check with a rabbit-experienced veterinarian is recommended within the first week after birth, particularly for first-time breeders or if any kits appear weak or underdeveloped. The veterinarian can assess the overall health of the litter, check the doe's mammary glands and body condition, and provide guidance on any concerns.

During daily nest checks, watch for common issues in newborn kits. Bloated or discolored bellies can indicate digestive problems. A kit that is cold and separated from the group may have been pushed out and needs to be warmed and returned. Discharge from the eyes or nose, lethargy, or failure to gain weight are all signs that warrant prompt veterinary attention.

The doe should also be monitored closely during this period. Mastitis — infection of the mammary glands — can develop and will affect her ability to nurse. Signs include swollen, hot, or reddened teats, reluctance to nurse, and reduced appetite. Retained kits or placental material can also cause serious postpartum complications. Any sign of straining, bloody discharge beyond the first day, or sudden lethargy in the doe requires immediate veterinary care.

Keep a simple log during the newborn period. Record the number of kits, daily weights, any concerns observed, and notes on the doe's appetite and behavior. This record is invaluable for identifying subtle trends and provides useful reference information for your veterinarian if any issues arise.

Most Mini Rex litters progress smoothly with attentive basic care, but knowing the warning signs that require intervention can mean the difference between losing a kit and saving one. The most urgent concern in the first few days is hypothermia. A kit that is cold to the touch, pale, and limp needs immediate warming. Place it against your skin or on a towel-wrapped warm water bottle and warm it slowly over twenty to thirty minutes before attempting to return it to the nest.

Failure to thrive is another critical red flag. If a kit is not gaining weight or is visibly smaller than its littermates after the first few days, it may not be nursing successfully. Check the doe's milk supply by gently pressing near a teat — a small bead of milk should appear. If the doe appears to have insufficient milk, consult your veterinarian about supplementation options.

Diarrhea in very young kits is a medical emergency. Their systems are fragile, and dehydration can set in rapidly. Watery or discolored stool, a soiled vent area, or a foul smell from the nest all warrant an immediate call to your veterinarian. Similarly, any respiratory distress — open-mouth breathing, clicking sounds, or nasal discharge — requires urgent attention.

Doe aggression toward the kits, while uncommon, does occur, particularly in first-time mothers. If the doe is scattering, biting, or trampling the kits, remove the kits to a separate warm container and allow the doe to nurse under supervision only. Consult your veterinarian or an experienced rabbit breeder for guidance on managing the situation.
