I ordered a couple of these for 2 people that took cat's I rescued. After seeing their cat's in them, I ordered 2 more for my cats. They love it. The Hammock part is ideal for lounging.  The lower part is bigger than most cubby holes. Price was real good, easy to put together. I will continue to order these for those that take rescued cat's. And will be ordering another for my 3rd cat. 

Pros: Easy to assemble. Cats love it. 
Cons: None
