I was excited about this piece, to really start catifying our home with four cats. So far they haven't used it much, and we are going to work on extending the wall path so there is a second exit. Anyway, it is well made and easy to hang up. It is very sturdy on the wall and holds the cats securely. My husband doesn't like the white carpet, especially on the large cave-like box. Personally, I wish this cave-box had 1/2 or 2/3 of the face cut away so you could see if a cat was in there and so there would be less carpet. My husband also wished there were more color options.
