My cats love this tree! It's very heavy and stable. My only complaint is that the carpeting sheds like crazy (as you can see on the floor in the attached photo). I can vacuum every day and there is still more to clean up. The carpet is quite thick and plush, so I'm not concerned about the tree being bare. The constant loss of carpet fibers is a pain to try and keep clean. I thought the problem would go away after a week or so, but it's been over a month and there doesn't seem to be any sign of stopping. Still, my kitties are very happy with their new perch and I'm sure it will last for years to come.
