I received the cat condo quickly, and I put it together at my office/warehouse in about 3 hours. I have a cat that was a throw-away animal by his first owner, and he lives in the warehouse and is a chunky little boy because he is afraid of being around other people, and doesn't like to be outside long. We put a few treats on the different levels when we leave and he sure likes that and he can see outside and get exercise. My only complaint is the stairs, they just lean on a metal thing, so fall a lot. Not a big deal, and I would recommend the condo as it is sturdy and nice looking.
