Not only do I love the cat tree but the kitties LOVE it too!! The only thing they don't really seem to use is the ball maze but other than that. They sleep in both houses they go up the ladder and play with all the little toys. Ruby takes a nap in it every afternoon and loves to sharpen her claws on it. I've been very happy to watch them play and enjoy this cat tree. Great deal for the price. Very easy to put together and sturdy enough for 2 cats to play on it. Love it.
