Sorry to go on about this but I dont think I can cope. My two 15 week old mini lops are CONSTANTLY mounting each other. They are brothers and I know its natural but its at the stage they just wont leave each other alone and I think its going to lead to them falling out. I planned to get them castrated in ten days time but am considering bringing it forward, if it would help. Will having them done calm them down? I dont mind it happening a bit but they are not playing or running about in the house as they are on top of each other. Please advise- I love them but dont have space to get them both a girlfriend.
