My cats love the cat tree it's very well made and easy to put together I did make the modification as recommended by another reviewer because I also thought it would be hard for my cats to reach the top level but once it was up my cats climbed right up the side all the way to the top! customer service is great I did not recieve the cat tree the first go round due to it being delivered to the wrong address but when I called they immediately sent a replacement I would definitely recommend this company
