Baby rabbits should be fed Kitten Milk Replacer (KMR) or goat milk, which you can buy at pet stores, or sometimes even a local veterinarian’s office. Because rabbit milk is the most caloric of all mammals, we add in one tablespoon of 100% heavy whipping cream (no sugar) to each can of KMR. Most kits will not nurse from the baby animal bottles you can buy at stores. Instead, use a sterile oral syringe, which can be purchased at most pharmacies.
It is best to feed baby rabbits no more than twice a day, but sometimes it takes more feedings to get an adequate amount into them, especially at first.You may loosely wrap baby in a soft face cloth or hand towel and lay it on your lap or in the crook of your arm. If bunny will NOT eat this way, of course, do the best you can. It is ABSOLUTELY CRUCIAL to let the baby eat at it’s own pace—especially if it is not suckling from the syringe willingly. If you squirt the liquid in too quickly you can aspirate (get liquid in) the lungs and the rabbit will suffocate.Baby rabbit eyes open at about 10 days of age. You may start introducing them to hay and pellets at this point, but no veggies or fruits yet. Just leave some timothy or orchard and alfalfa hay and pellets in a corner of the box where the babies can easily get to them.
Hope this helps and best of luck to you and the rabbits.
