I know people use vinager if the bunny is peeing and pooing in one spot instead of the litter box but I'm not sure about for not chewing. I know there is something else but I just can't remember what it's called. I know a few people on my rabbit forum that have there bunnies as free roam of the whole house all day!! I wanted to do it before but my parents wouldn't let me. lol I would hope she can't jump that high either, she'd be super bunny!
