We were a little worried at first, but after day 3, she jumped up on the third level to get a better view of the yard. The top level is a little "tippy," but the cat doesn't seem to mind. She hasn't tried the "kitty cave" yet. It probably reminds her of the pet carrier. She loves scratching her claws on the sisal posts, so as far as I'm concerned, it's a win-win!
