I have a pet mini-lop. Two years ago, I noticed his front bottom teeth were growing over his top ones. So I regularly clipped them.(ick). Last year, they seemed to be growing OK, so I patted myself on the back for having corrected the problem. Today I took a good look at him and sure enough the teeth are messed up again. And on top of that, there are more teeth growing in in back of the top ones! Can I do anything to get these teeth to get gnawed down? Other than a daily carrot, would anything else help to keep them in shape?
