I have a rabbit (my favorite) that I keep in the kitchen. This morning I came downstairs to find six little babies on her cage floor. I didn't even know she was pregnant! I will sometimes let her out of the cage for exercise and to let her socialize with my dog and two indoor cats. She likes the cats but the dog is too playful for her. One time, my male rabbit got out of his cage but with all the commotion, I didn't think he could have mated with her. She was born in September so I wasn't planning to breed her until the end of January.
