We bought this new for a stray cat that stays on our porch but it refuses to use it, she won't even go near it. She has not been in it at all. It does have a few light dirt spots on the outside as we left it laying in the garage and something was laid on top of it but does not affect it in any way. We tested the heating pad and it works fine. We didn't put the legs on it but they are with the house. I no longer have the original box it came in. Smoke free. Measurements in the pictures.
