My small orphaned baby bunny won't drink kitten milk replacer.

Lowfat cow's milk does not have the appropriate nutrition profile for baby mammals. I recommend kitten milk replacer. If you do not have access to kitten formula, you can make a homemade formula: 1/2 cup whole milk 1 egg yolk 1 drop pet multi-vitamin 3 crushed Tums (antacid) Mix in a blender and replace every 2-3 days. This homemade formula should only be used until a balanced pet formula can be obtained.

Kitten milk replacer (KMR) or goat milk should be fed to nursing kits (baby rabbits​). Feed twice daily. Be aware that bunnies can be very difficult to hand raise. Follow the link for more information. http://rabbit.org/faq-orphaned-baby

1/2 Cup evaperated milk 1/2 Cup water 1 egg yolk 1 Tablespoon Corn syrup Kits should be fed every 6 hours for the first 2 weeks, then every eight hours the third week, and every 12 hours on the fourth week. After that the kits should be eating a good amount of solid food, and they should be drinking water. If they seem to be doing well on pelleted food, discontinue the formula. Otherwise, feed once a day until they are six weeks old, or until they to well on solid food. Feed a good quality grass hay starting at four weeks, and do not feed any moist foods such as fruits or veggies.

If this is a wild rabbit it needs to be returned to where you found it or call a wildlife rehabilitator. Wild rabbits typically die in captivity. http://www.2ndchance.info/bunnies.htm If a domestic rabbit here is more info on raising. http://www.bio.miami.edu/hare/orphan.html Much depends on how old the rabbit is. Babies are only nursed twice a day and are usually weaned by 4 weeks old.

You will need to add some heavy whipping cream to that milk for it to be suitable for rabbits. I suggest you refer to this article on how to care for baby rabbits. ( https://www.mybunny.org/info/caring-for-newborn-baby-rabbits/ )

It would be helpful to know how old the rabbits are. Can you please post again with more information? Human powdered milk is not a good substitute for kitten milk replacer. I suggest you try to find the kitten milk from either another shop or order it online. Many vets have this on hand in their office so you could always call a local vet and ask to buy some. Feeding the incorrect nutrition can be deadly to baby rabbits. In a pinch you can use goat's milk but get them back on kitten milk as soon as you can. Here is a link about how to care for baby rabbits that may answer more of your questions. ( https://rabbit.org/caring-for-orphans/ ) Hope this helps. Best wishes.

This diet is not good for your baby rabbit, she might not survive because her gut flora might change for the worse. i would recommend feeding her kitten milk replacer only, you can find it in any pet store.
