i can't seem to make kitty understand that my bed and my desk chair are not scratching posts, and he's doing some real damage to them. my bed is fairly new, and he's trashing the box spring. he has scratching posts, the cardboard kind, which he totally ignores, and he has a whole chair that i don't care what happens to it. he doesn't pay much attention to the chair either. it seems he only scratches what i don't want him too! how can i get him to scratch only the appropriate things and leave my bed alone?
