If I could I'd give it 2 1/2 stars for the sisal (my previous cat scratcher was one of those catastrophic cardboard things that shed all over the place) and the sturdy construction. However, it is top-heavy, the cubbyholes are too small for larger cats to fit into, and WORST, the hardware is an unconscionable fail. The bed platform for the top comes with a bolt too short to reach through both layers of pressboard far enough for its threads to engage. I wound up assembling it with pegs made from broken chopsticks and hammered into the hole. Shameful.
