The housing parts are very big. Big enough for a very large cat or even 2 cats, large and small. Colour is great so is the fabric. The housing part is already assembled so you only have to put in the support poles. Very easy to put together. I had it up in 20 minutes and I am disabled. My cats love the big space in the housing and the soft pillowy platforms. They are almost an inch thich in the middle. GREAT PRODUCT!!
