The "house" and top are too small for my 11 & 12 lb cats but I kept it because when I got the bottom put together without the house one of the cats jumped up and went to sleep. In fact she's asleep on it now as I write this. The house with the top bed is beside it but neither cat uses it to sleep on or in. I should probably just give that part to a rescue because I'm sure smaller cats or kittens would love it.
