This cat tree was an instant hit! My kitten was all over it before I had even built the 2nd tier! It's very sturdy, heavy material (not plywood) and I'm confident that even as an adult this will hold up well. Something I noticed just now was that my perches are fluffy around the edges, like they have stuffing in them! I don't mind because kitty loves them. The directions look complicated at first, but once you see what they're getting at it's really easy. Definitely worth the money!
