My family is moving. I bought this kitty enclosure to aid in the transitional process. It arrived very quickly. It is very easy to put together. My 12 year old son put it together in a few hours entirely on his own, with a screw driver. It is very sturdy and looks nice, too. The kitties are thoroughly engrossed with being outdoors (but still safe). It is pretty easy to wheel around! All around a great enclosure, especially if you are looking for a quick and easy solution.
