That sure is a beautiful cat tree. I'm glad that they're getting more used to it and using it more too. When I first adopted Sky, I don't think he had ever seen a cat tree before because he seemed very scared of the large ones I have out in the living room. He finally got used to them and would sit on the bottom or second level. Now he loves them and will sit any where except for the highest perch. I'm sure that in time you won't be able to look at the tree without at least one cat being on it.
