I had two baby male bunnies socializing with him through a divider, like three weeks old maybe, and he kept breaking through to mount them, then I got a different male named Oreo who was significantly bigger then him and oreo would mount him to the point where Yves was terrified so I got rid of him and now Yves doesn’t like male rabbits… I’ve never noticed Yves spraying or anything like that, he only uses his chin to mark elephants tail. If he won’t need a mate I’ll leave it be but I don’t want his life becoming shorter… maybe a female will just find him, we have a few in the neighborhood but they don’t stay in one place long
