I have just had both my male rabbits "done", they are brothers and have never been seperated. One brother used to hump the other so we thought it best to go ahead with the operation on both. Its been less than 24 hours since the op and the roles seem to have been reversed, Bert is now humping Ernie. I also thought that it would stop Ernie biting, he started this about a month ago, and its getting to the point where he goes for me for no reason at all when I let him out. I let them out today, he was fine, he was by the side of me, I stroked him for a while, then he just went for me. Please help, Im really stuck with what to do next!
