Yes, I get Christmas gifts for the cats. Two assembly-incompetent adults were able to put together in about an hour with one Philips screwdriver. The hardest part was the first step - attaching the stairs to the left side. Loved the  screws necessary for each step were in letter-coded plastic bags.
Turned out beautifully. It is now on the deck overlooking the snow; and the cats are in the nice warm house. Just wait for summer.
