My cats loved this product so much that I purchased 3 of these cat towers for my indoor/outdoor kitties and they just love the deep dish to hide, play or curl up and take a nap. The high walls make them feel safe and they fight to be on the top level. I had been looking for something that would offer protection from the outdoor elements and I think this tower is the ticket. 

Pros: Solid wood with household grade carpet
Cons: The top dish needs to be installed with a power drill
