Santa bought this for three black kitties. All three of them have played, scratched, climbed and slept on this. Didn't have to put catnip on it to entice them either!
It shipped quickly and wasn't too difficult to put together. But then again I drank wine and watched my husband put it together. 
We had a bad screw on the middle section and when I contacted Wayfair, they sent out a replacement for the entire section including hardware! Great customer service! So on behalf of Murphy, Porter and Arthur Guinness, it is purrfect. The picture attached shows Arthur G as king of the mountain, Porter (big 15 plus pound boy) on second tier (Murphy was using the litterbox during the photo shoot)
