Great for bigger cats, sturdy. Only complaint is there’s a hole in the first platform so the cats can get from the floor to the platform but the second platform is just as big as the first so there is no real way for them to jump up there unless they are young and still jumping high. My elderly cat can only use the bottom part of this tree. If there was a hole or a staggered platform to reach the top it would be 5 out 5 stars
