I have five cats ranging in age from 3 to 13 yrs., including a long-haired cat who weighs 18 lbs., and they all love this cat tree.  I have it near a window so they have a great view of the bird feeders, but they like to nap on the upper levels and in the cubby.  The neutral color blends in with the room, and we have fun watching them play on it and try to jockey for the top level.  Great product!
