This would be great for kittens or small cats, but if you have a chunky cat, he's going to be disappointed and embarrassed that the upper posts struggle to support his weight. Also, there's not chance he'll ever fit in the hole, so it ends up being more in the way than functional. He also managed to check through the strings holding the balls pretty quickly. It was decent for the price, but I might just spend a little more and get a sturdier one next time.
