My cats like this condo a lot, although the internal cutouts don't really seem necessary since it's pretty short, and the cutouts make the floor space smaller. I have one large cat (15 lbs), and while he likes the top, the cubbies are a bit tight for him. My smaller cat (9 lbs) is perfectly happy with it, and it looks a lot better in my living room than the taped-together cardboard boxes I had for my cats before!
