I love the baby blue color! My 10lb cat is too fat to get into the circle thing so I just might remove it. Also the very top level is too small for him to fully lay on so all he can do is sit up there...He has to lay on the lower levels. He loves scratching and holding onto the posts like a little monkey lol I love that he enjoys it so much. I just wish it had more dangling toys. The unit is sturdy and nice quality. It was a tad tricky to put together but I was able to do it myself. My cat and I are happy with this purchase
