Bought this to give shelter to a stray cat that adopted us a couple of months ago. The flaps are smaller than they look in the pictures, he is normal size but has to squish himself through and does not like the door at all. I agree with another reviewer in that the flaps should open both ways, the cat won’t push through so we had to tape one open which defeats the purpose of buying an insulated house. The house in general is sturdy and seems nice and toasty with an added heating pad. That being said, he won’t actually stay in there unless it’s raining and prefers the softer canvas heated house we got him. It is smaller inside than I had anticipated, perhaps he feels a bit too confined in there. The hinged roof is a plus, makes cleaning the bedding a lot easier. Overall I’m glad we purchased it, it’s more weatherproof than the canvas house.
