I really love this cat condo. One thing that I would like better is if the sleep areas were just a bit bigger. I have three cats, 12 lbs, 10 lbs, and 5 lbs. The two larger cats won’t even attempt to sleep up in the nap areas. I suppose they think they wont fit. The kitten loves it and takes naps all the time. 
I had to being back my old tree with flat nap areas that were a bit larger so the bigger cats could feel safe to nap. 
I love the material and it is well built.
