I bought this when a close friend raved about how much her cats loved theirs. I have nothing negative to say about the product itself, per say. It seems pretty sturdy and well-built, but my cat just didn't ever seem interested in the "race track" part of the toy. I tried rolling the ball around while he watched, and he not only didn't play with it, but walked away immediately. If the cat could shrug, he would have. Despite my several attempts to encourage him, he never did show any interest in it at all. Except, that is, as a scratching post. In that capacity, he did enjoy this toy. Maybe a little TOO much. He tore the cardboard to shreds with his teeth and left quite a mess in his wake. While I appreciate that he was interested in the scratching surface, I have purchased much less expensive "scratchers" for him that he used and seemed to enjoy just as much. I suspect that a kitten or younger cat (my cat is 8) might be more inclined to play with this in the way that it was intended.
