This is a great cat tree! I have three cats and all have used it. They pretty much just stay on the top two floors and they all love the highest perch. The only negative I would say is that the fabric isn't like the real carpet I had on my other cat tree I purchased at Petsmart. I didn't think it would be as easy to climb on but my cats are still using their new house and don't seem to mind - carpet or no real carpet.
