It's very important when buying a cat condo to make sure the measurements are correct. I read all the reviews and everyone said adult cats fit perfectly on this. My cat does not. He's not even a full grown adult yet and he's way too big for this. He knocks it over, its wobbly, and overall just way too small for him.
I'd recommend to anyone with kittens or a smaller breed of cat, then this would be perfect!
