My cat doesnt like it. He only goes in the cubby at the bottom. I put him at the top and he seemed to like it but then hit his paw on the edge of one of the platforms while leaping off it. He doesnt know how to climb it or come down from it. Maybe hes not too smart He does have a small head. Also it was missing 4 toggle bolts so I suggest an inventory of the hardware before building it. It was easy to put together.
