Some rabbits chew all their life and sometimes as they get older the need to chew diminishes. It could be due to boredom as well. So maybe you could divert him to something different but he obviously enjoys chewing.

As for the biting, hopefully that was a one time incident. Rabbits do sometimes nip to get attention.

Well, chewing paper and cardboard is extremely normal – I would just try to keep these things away from him. I don’t leave anything on the floor or near the floor that I wouldn’t mind teeth marks in. That’s just part of having a bunny. They might learn that furniture and carpet are off limits, but they can’t understand why that book is not ok to chew while a phonebook is ok.

As for carpet, does he pick one spot? If there’s a specific place he goes, you can try covering it up with something appropriate, like a grass mat or cardboard that he is allowed to chew. Or just blocking him off from that spot.

For biting, I would try a high pitched yelp every time he nips. This is how bunnies tell each other that a bite is too hard. Otherwise, I’ve had success using the ignore technique – if he bites, turn away (or walk away) and don’t give him any attention. He probably doesn’t want you to leave, so he will think twice about biting.

I discovered thumping at Moose when he is being bad works too, he’s a sensitive boy, he doesn’t like any disapproval aimed his way

LOL, Monkey. I’m laughing imagining you thumping at your bunny. Do you do it with your foot, in true bunny style?

I’m also assuming this technique doesn’t work with Monkey. She doesn’t seem to feel shame

Nope, doesnt work with her majesty. She just glares and me and the turns and flicks at me.

Sometimes I do it with my foot. Depends on if im standing or not. If im on the floor, i usually use my hand
