This elevated cat house keeps outdoor and feral cats warm through winter with an 18-watt waterproof heating pad that raises the interior temperature by about 20°F, and a built-in smart thermostat with over-temperature and over-current protection keeps it running safely day and night. Inside, layers of aluminum foil and pearl cotton trap warmth against the cushion, and a soft blanket keeps your cat's belly cozy even on the coldest nights. The shell is made from 900D Oxford cloth with a dual-layer PVC waterproof coating, so rain and cold air stay outside while your cat stays dry inside. Five support legs, reinforced with PP support pipes, keep the shelter steady even when the wind picks up, and the interior measures about 12 x 15.4 inches, sized for a small to medium cat, with a 5.9 x 7 inch door curtain for easy in-and-out access. At just under 5 pounds and foldable for storage, this heated cat house is an easy way to give a backyard or feral cat a warm, private place to shelter during cold weather.
