Kimchee chewed up a big corner of my rented apartment wall when I went out for groceries. I put bitter apple and it worked. He never chew any wall anymore, now he is grown up, so no more problem for me.
I would suggest you to use an x-pen/playpen (in the kitchen, for example), so it will confine them and avoid them in contact with anything (eg. walls, wood cabinet, electric sockets, etc.).
Good luck! |
