By which I mean rabbits which prefer to be on their own. One of my male bunnies is really unhappy with other buns. He would take their submission as 'aggressive' and would mount the head or back of one of my neutered males. I would let him mount him (not his head) as I was told this helps them establish dominance. However he wouldn't stop to the point of annoying the other bunny who'd then get annoyed and then there would be scuffles. I hate the idea of having him Alone as there is so much said against this. Perhaps a female would be suitable. I just don't want to face having to rehome a bunny if he still doesn't get on with them. Funnily he gets on with my cats just fine and I often find him cuddled up with one of them! Surrogate bunny perhaps!
