When I brought this in the house from the delivery both of my cats were smelling it. Then after that they both jump on the top then the other cat went inside the tunnel. The one on top was hitting at the one in the tunnel then they both started chasing each other. They seem to enjoy the kitty cat condo. It is so cute. It seem to be sturdy so I put it in the living room next to the sofa. It looks very nice there. I am glad that wayfair have nice items for the cats.  Pros: Its a good value      Cons: can't think of any.
