I got my bunny, Floyd, in mid-June last summer. He’s always been fairly aloof and doesn’t like to be petted. Any attempt to do so results in him scurrying away. He used to be afraid of people even walking by him, but now he doesn’t have that problem. He’s never been an affectionate mini lop, and I’ve just come to accept it. The only time he would let me pet him is when I was feeding him at his cage entrance.
However, I got him neutered about 3 weeks ago. Since then, his aggression and territorial tendencies have increased even more. He fervently chews on his cage bars at all hours of the night (despite having plenty of space and toys), constantly is trying to flip his litter box, growls at me when I’m scooping his food into his bowl, and growls/claws at the cage bars angrily if I poke at his nose trying to get him to stop chewing on the cage bars. He won’t let me pet him anymore, either.
What could be causing this and what can I do? This is very frustrating, and I don’t know what to do to get him to trust me again after getting him fixed, or to lessen his aggressive/unsociable behavior. Please help!
