We've basically given up on training this cat. Nothing works, unfortunately. He's smart enough that he just waits until you leave the room to start clawing. He is also the most destructive cat we've ever had, and has a thing for shoes. If you leave a pair on the floor where he can get to them, they will get shredded. And, after he ruins something, he loses interest in it completely. If we get another cat when he is gone, it will be declawed. We asked the vet about having him done, but we didn't know that it should be done when they are a kitten or it would be painful and expensive, so we just let it go.
