I have 4 cats...but so far only 2 have been able to see it and use it, they like it. But when i opened the box, everything was good, until I saw the size of the top 3 platforms, WAY TOO SMALL!! Only 10 inches across, they can only sit on it. if they lie down or nap they'd fall right off. but they're having fun napping and playing together in the other compartments. They only sit on top to look out the window. SO I give it 3 1/2 stars! 

I got the brown and tan.
