I love this cat tree and my cats are getting acquainted with it too and seem to like it.  It comes up to the window sill of the room it's in so they can see out. The top beds are big enough for my 14.5 pound cat and the large middle space is fun for them to stretch out on! They haven't found the sisal scratching posts yet, but I"m sure they will enjoy them as will I!!  since they might keep the chair from getting scratched. A great buy.
