I have had rescue cats for 13 years, and my own. They all love these trees and Armarkat is so much more reasonable price than buying at a pet store. They even sell replacement parts if some of the rope eventually wears down. I have ordered for others, cats love them. These have a lip around the edge of the towers so kitty won't fall off. I cover the sleeping spots with fabric (I buy used baby swaddlers at the thrift store) so I can wash them every couple of weeks. You can clean the hair from the fabric if needed, by using a soft cat wire bristle brush, works like a charm. I have three of these, and they last and last.
