Why Do Domestic Rabbits Bite? At BackyardBunnyNews, we help people who want to raise rabbits and bunnies by collating information about the hare-raising experience. If you have a domestic rabbit, it is likely that you are wondering, “Why do domestic rabbits bite?” Biting is surprisingly common in domestic rabbits, and it can be a sign of a few different things. For example, some rabbits may bite to protect their young, while others may bite out of fear or stress when fleeing a predator. These behaviors are often harmless and can be prevented if you keep your rabbit calm and teach it not to hurt you or other rabbits.
