I love the way this looks in the apartment (I am not a fan of those standard cat trees). My cat LOVES the bottom part, the platform, the pompom and the scratching post. He has only ever gotten into the ball part once. I think it's an awkward distance for him to jump, so I just store his toys in there. But he likes to jump on the top of it and watch me in the kitchen. At least he used to, before he got a bit too enthusiastic/ambitious and jumped from the cabinets to the tree and knocked the whole thing over. I think he's a little freaked out by it now. Docked a star because it was a little bit of a pain to get the legs attached, and for the fact that my cat was able to topple the thing (he really went for it though, haha). But otherwise I'm happy with the purchase.
