We got this for my Grand-Cat to visit me. He was a shelter cat and newly come to my kids' home, and then he had to make a trip. He is a little active and he needed a place that he could climb and explore. This was a great answer. It didn't seem as expensive as some of the others, especially considering its height.  It came very quickly , was very easy to put together and the cat loved it right away. There is nothing to complain about here.
