We lost our 21 lb,.17 yr. old Siamese last month and found an energetic 18 month old Maine Coon at the Humane Society. He immediately started climbing my bookcases, and everything else in sight. Sometimes the only way we could find him was to listen for the crash of something falling down and breaking. We ordered this 68" Cat Tree and he fell in love with it. He's up and down on it all day long and sleeps on the top perch. He even uses the scratching poles instead of my furniture. It was very easy to assemble (if I can do it, anyone can). It was also dedlvered in only a few days. I would give it a five star rating but as they say, nothing's perfect. It wiggles a little when he (Tuxsey) runs up it and the little toy that's suppose to hang from the top shelf only lasted 2 minutes. We love our cat tree and would recommend it to anyone.
