The good: This is a very sturdy and attractive cat tree. I appreciate that it is easy to clean every part of it. The bad: The sizing is off. This is really for kittens and small cats. If you have a normal to large cat, it might not work. Even the sisal supports are too thin for my cat to scratch. I had to take the top perch off because it was too low to the box for my cat to get on the tree. He loves being on top of the box now that he has enough room, but that's the only part of the tree he will use.
