My mom was saying that she thinks Benji is lonely, and could use a friend. He is out of his cage for a couple hours a day, but because of the dogs he can't be out all the time.

I've been reading articles and can't seem to find an answer. Should rabbits have the company of other rabbits, or would they be better alone?

Benjamin seems pretty solitary to me - he doesn't like my friend's rabbit much, and their both neutered. But does that mean he doesn't want any bunny friends, or just not that bunny?

And I read that guinea pigs and rabbits sometimes make better friends than rabbits and rabbits... but I had read before that a rabbit can accidently kill a guinea pig if they are housed together.

Any advice from other rabbit owners?
