I've had these two little mini-rex bunnies since christmas eve 2010. I have a girl and a boy. i'm not exactly sure how old they are, but i think it's a little young. They are " supposevly" brother and sister and they have shared a cage since christmas eve. they are inside bunnies until it gets warmer. i was wondering since they've been in a cage for so long if the female could possibly be pregnant? please help! Thanks
