Bella loves her new cat tree and her favorite perch, naturally, is the highest. This tree is not quite as stable as I would have hoped for though. When she runs and bounces off the cantilevered shelves, the tree rocks (it's sitting on carpet) and I'm afraid one day she might pull it down. Also, the faux fur covering the wood is thin and doesn't give her much to grab on to when she's playing/running. This tree would be better for a smaller cat (less than 10 lbs). A wider base would prevent the instability.
