Can female bunnies live together?

Okay, so what you have heard about females being fixed is true. If you want your bunny to have a friend, you have to get her, AND her companion spayed. Spaying is pretty safe with rabbits, she is not likely to get hurt especially if it is an experienced vet. Also, I discourage you from wanting to breed her someday. Breeding is a big responsibility, and many problems can occur, with much much higher risks than spaying, ESPECIALLY for older rabbits (most breeders don't breed their does once they get past 2 years) and especially for a first time mother. If you bred her, you would be asking for problems. So, getting her a friend is a great idea, and she would love a companion, but her and her friend must be spayed. It usually doesn't cost too much. If you don't want to spay her, then she will have to stay solitary. God luck, and remember as much as she would like a friend, she will be okay without one too. Rabbits are not like rats that need companionship from other ratties, they can get all the love they need from their owner.
