* Scent changes: Rabbits have a very sensitive sense of smell. After 36 hours, the kits will have a different scent, and the mother may not recognize them as her own.
* Rejection: The mother rabbit may reject the kits if they smell different, which could lead to them being abandoned or even attacked.
* Stress for the kits: Being separated from their mother for an extended period can be stressful for the kits, and they may not be able to adjust back to the nest easily.
What to do if the kits have been separated:
* Consult a veterinarian: If you have been separated from the mother rabbit for more than a few hours, it's best to consult a veterinarian to get advice on the best course of action.
* Introduce slowly: If the kits have been separated for a short period, you can try to reintroduce them to the mother gradually. Place the kits near the nest box and let them get used to the scent.
* Monitor closely: Watch the mother rabbit carefully for signs of aggression or rejection. If she shows any signs of rejecting the kits, you may need to hand-rear them.
Prevention is the key:
* It's best to avoid separating newborn rabbits from their mother whenever possible. If you need to handle the kits, keep the separation to a minimum.
* Use a clean, warm towel to handle the kits, avoiding transferring any human scent to them.
Remember, rabbits are delicate creatures, and their young are especially vulnerable. If you are unsure about anything, it's always best to seek advice from a qualified veterinarian or experienced rabbit breeder.
