3.5 stars. This is such a cute concept and our kittens love it. I will complain that the green carpeting is very thin and almost slippery, so it feels very cheap and is not soft. Our cats have gotten used to it. Overall, we decided to keep this because we already put it together and it is a different look than other cat trees and matching other cat items we have. If you don't mind that the green carpeting is super cheap and does shed, then get this.
