I just got my other female bunny (she's not neutered yet) and I wanted to see how well they can get along with my other male rabbit (he is neutered). We put them in an other room and my male bun started chasing the female bun while trying to mount her (i think?). They were doing this for a while and I noticed that the male bun was clinging onto the female (on her back). I don't think he injured her, I think he was just biting the fur. After that I put them in their separate cages, and the female is pretty still, she hasn't moved. I doubt that she's hurt, she isn't grinding teeth or struggling to move. She was thumping for a while so maybe she was a bit traumatized? Does this mean my rabbits don't like eachother or is this natural in bonding?
