Hi! Poor bun, hope he/she gets better soon! Inside of toilet rolls stuffed with hay are a popular choice. Also I have found that cutting holes in old plastic coke bottles then stuffing with hay and treats is quite good. I know some people on here will disagree on this because of chewing plastic, but my lot are real chewers (they once ATE a plastic treat ball!) and they haven't even tried to nibble at it! :thumb:
