Review on 🏡 Rest-Eazzzy: Weatherproof Outdoor Cat House with Portable Handle, Eco-Friendly Materials, and High Platform - Perfect for Outdoor Cats, Dogs, and Small Animals by Tressy Rakowiecka

This should work well for keeping the cat warm on the back porch. Includes 5 wooden legs. One of the surviving legs was badly damaged by termites, but we managed to save it and everything should be fine. The legs are unfinished. It would probably be a good idea to put a watertight seal on them. I just sprayed them with WD-40. I'm not sure how long it will last in direct sunlight or harsh conditions, but it should last quite a while on a covered porch in inclement weather.
