The K&H Thermo-Kitty Bed features super soft, extra thick, orthopedic foam base with a built-in dual thermostat, 4-watt heating unit. When in use, this warms the surface 10-15° above the ambient air to match your cat's normal body temperature.
The surface of the bed will be about 15°F above ambient air temperature until the pet lies on it. Then it will warm to about 102°F, which is the natural body temperature of dogs and cats. Indoor use only; for garages, an outdoor heated product is recommended as it will be better suited to handle much colder temperatures. This bed does not include an on/off switch, and is always on when plugged in.
Washing Instructions: Remove the Pet Bed Warmer from inside the cushion. Remove the foam ring from inside the cover. Wash the cover and cushion on the gentle cycle with cold water. Line dry or use the no-heat cycle on your dryer.
