Our cats really like the tree but the house and perch are a little small. Neither of our cats would be considered a big cat, but they both spill over the sides! They still really like it and take turns sleeping on the top perch, but I'd recommend making the house and perch slightly larger. They hang their heads off the side and it doesn't seem very comfortable, kind of looks like they are choking themselves! Also, the beds are very hard as others have mentioned, I ended up putting little IKEA cushions on them. If you have a big kitty this might not work. It's a little wobbly when they jump up to the top perch but other than that it's good quality, easy to put together, and much nicer looking than the typical cat trees/condos!
