We have 2 cats - both 15 years old.  The boy cat was impressed, but the girl cat behaves as if it was just what she was wanting!  She has been sitting on the top perch keeping her eye on everything going on in the apartment!  She rolled all over the soft rug covering and has already sunk her claws into the posts - which is why we purchased it. We are really happy with the purchase!  

Pros: The box it comes in isn't too heavy and it was easy to put together.
