This cat tree has pretty decent construction, but I wish the sisal rope went all the way up and down the posts instead of just covering part of the posts. I have a 6-year-old rescue cat named Fifi whom I bought this for. She weighs 13.6 pounds, and it just didn't seem quite big enough for her. She also never uses the perches on cat trees, which doesn't help. I ended up re-selling this to a friend of mine who has a much smaller (2-year-old) cat named Gatsby this is working out really well for him.
