This tree is adorable. It is perfect for tiny kittens just learning to climb. The rattles in the balls are great. The sticks for the balls are too close together. We had a kitten get stuck between them. The platform for sitting is not very strong. It bends a lot when any of my cats sit on it (they all way 5 to 7 lbs). I would not recommend this product for a cat heavier than 8 lbs.
