Both of my adult cats can fit on the larger shelf, at the Same Time, to eat! We needed something to keep the kitty food up & out of the dog's reach. And they use the scratch-y posts, too! I almost gave it 4 stars (instead of 5) because it is just a little bit wobbly, but since that is the only thing I could find wrong with it, and they can get from platform to shelf without knocking anything over, I think it deserves the 5 Stars.
