I bought this for my cat, Junior so he had a perch to look out my kitchen window. He seems to really enjoy it. I initially hid cat treats in it, so it became a positive experience for him. 
It was very easy to put together. I did it after working a 12 hour evening shift, and it took less than a hour, with his "help" of course!
Kudos to Go Pet Club and Wayfair. Com for this quality product!
