The house is easy to put together but the screws don't really line up that well. I am using this in my outdoor Catio. I had to staple the flaps on as they don't really stick. I put a Sunbeam handwarmer inside, under a cat bed, and plugged it in so that the cats can go inside to snooze in warmth. Of course they can come back inside the house but like to stay out in the shelter. This house is reasonably priced, just be aware you have to make small adjustments to it.
