The rigid exterior will hold up to any use. The extreme weather design keeps outdoor cats warm down to the lowest temperatures mother nature can throw at it. Half the floor is heated by a K&H Small Animal Heated Pad so the cat can choose to be on or off the warmth. Use in a barn, shed, porch, garage, under a deck or anywhere extreme temperatures exist. All KH heated beds and pads feature dual thermostats and are designed to warm to your pet's normal body temperature when he/she lies on the pad. When your pet is not on the pad, the heat will dissipate into the air and the surface temperature will vary according to the ambient air temperature. All KH heated products are thermostatically controlled to heat to 102° F, regardless of the size. Dual thermostat simply means there are two internal thermostats that will keep the surface of the bed at 10-15° F above ambient air temperature when your pet is not on the bed. When your pet lies on the bed, it will warm to about 102° F.
