My bunny bites me when I clean his cage, too, but that’s only because he’s not neutered. Now I close the room door whenever I clean his cage. When he does bite me, I pick him up and say “No!” very firmly. It has no effect.

I don’t know if there would be any difference if I didn’t scold him. Maybe you should try spraying your rabbit with water. I’ve heard that works – but I don’t have a spray bottle, so I can’t! Plus, I wouldn’t have the heart to spray my little bunny. He can get so sulky, and even though it’s funny, it’s not very fun to have a sulky bunny! 

I have been told to let out a little high pitched scream like “eeee!!!” when my bunny bites or nibbles as if he has hurt me (usually when I’m in his way and I didn’t respond to his nose bonk fast enough). He looks at me seriously when I do this and then gives me a little nudge or kiss to say sorry(at least that’s what I think he’s doing) and then he doesn’t bite again.

I also have been told that disciplining a rabbit like a dog is NOT the way to go. They don’t react the same way. I think you did fine, Pinky. You have to clean his cage, just keep him separate when you do it. and then when you let him back in maybe give him a little treat to thank him for allowing you do clean. If he gets upset, just leave him be until he calms down. I doubt it will last very long.
