interesting.... my two little darlings followed the same pattern. When we first got it they showed some interest in the leather couch, but responded quite appropriately and leave it alone now. The dining room chairs otoh (woven, but not by me) are irresistible...
Fortunately they also like cardboard flat scratchers and my girl likes tearing up a cat tree. (oh and they are diligently attempting to knock down the house by using a support post in the basement as a scratching post, but I think the post will win)
