I have 4 large cats and all of them love this cat tree! The black cat has claimed the top perch and for reference he is a 15 month old norwegian forest cat. We also have a 15 month old siberian forest cat and 2 very large DSH cats. This 36 cat tree was a smart buy for us. I spent a lot of time comparison shopping and the price for this size simply could not be beat. I put it together by myself, it took me 37 minutes from start to finish (yes I timed my work) and I have ADHD, so I feel that is an awesome time, for someone who is constantly (and easily) distracted. We love this tree so much that I just purchased a second, albeit taller, cat tree from wayfair!
