I have 3 cats (1 about 2 yo and 2 about 8 yo) and they have never had a cat tree before. The youngest feels like he is 'king of the castle' when he is on it the two older ones are still adjusting to it but they will get the gist of it. It is the perfect size not too big and not too small and it is sturdy.
Picture isn't that great sorry about that.

Pros: sturdy perfect size good price
