Our cats love it! One 16 pounds and one kitten. It is sturdy and stable when they both are on it. Bigger cat can fit comfortably on the top perch, but is really too big for the condo on the bottom. Kitten doesn't seem interested in the condo, but maybe she will when she gets older. All she wants to do now is run and play. Both cats use the scratching posts and seem to like them. I like how it looks...so much nicer than a carpet tree.
