So I would really love to let my rabbit have free roam of my little apartment, but he has a weird chewing issue. On our first test run, I left the room for just a minute and when I came back he was chewing on the lining of the wall! I still let him out, but he can only play under constant supervision, lest he do some redecorating that could cost a security deposit or more importantly his well-being. Do you guys have any advice on discouraging chewing where he isn't supposed to? I've tried toys and cardboard tubes to distract him but he still goes for the wall.
