It does sound a bit excessive (even for a kitten) but maybe the cat tree will help. Could you maybe buy a small sample square of carpet and rub catnip or something on it to at least confine the scritch scratching to one small area? She scratches walls too?? She's just too cute to get mad at but it really sounds like you're doing all you possibly can. What does Tito think of all this? Wish I had better advise. Good luck.
