I bought this cat tree because I foster abandoned/unwanted kittens.  It is a perfect size for them. The kittens absolutely LOVE the hammock.  It is also great because the top shelf is the same height as window sill, so they can sit on there an look outside instead of the window sill.  
It is a tiny bit uneven, and I've checked again and again and have the parts together correctly, but not so much that I wouldn't buy it again.   It is nice and soft, has sissel rope to scratch, a rope to play with, a comfy hammock, and a hidy place.   Perfect combination of things for any kitten to love.  My kittens thank you!
