I have 4 cats in all different ages and at first only the kittens were interested, but the whole brood really enjoys it. I bought it at a super price and wasnt sure that it would be sturdy. It really is, even the heftier cats can be on any level and it doesnt wobble or anything. The fur is holding up well. The cats appreciate the rope on the poles too. This product is wonderful. Very pleased with my purchase. For anyone that is thinking of buying it say to, but what I find the cats really like is if you put it by an window. They like to all be able to comfortably be able to look out at the same time and they love the sun shining in on them while they sleep
