The cat cave easily accommodates our two kittens! It's their favorite hang out spot. Our "older" cat  (3 years) most often chooses to sit on top of the cave. We have 2 large cat trees (both bought from Wayfair) but this one is their favorite. They utilize the multiple perches and scratching posts. It went together pretty easily. Of the two cat trees we have it seems my guys spend most their time on this one.
