My kitties received their cat tree very quickly, (as usual). I think they knew it was for them when I dragged the box through the door...they were more excited than usual. It didn't take to long to assemble. They are very good about sharing the little house. One prefers the round beds. I have 5 full grown cats and they're not little. This tree can hold them all no problem. It is a great item. I have it in a sunny room with sky lights above, so they're nice and comfy. Thanks O
