I have it positioned in a corner of the kitchen surrounded by windows, and there will usually be at least 1 or 2 of my furry critters on the ledges. I notice when it's cool or chilly, there will usually be one curled up in the little house section. I'm very happy to say that it's plenty big to hold larger cats, as I have several of those and they have plenty of room.  This isn't "kitten-sized", although obviously kittens would love it, too......and they don't stay kittens forever. Very happy with purchase.
