All K&H 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 K&H 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.. Includes small K&H Pet Bed Warmer Removable heater uses only 4 watts Traps kitty dander and hair MET Listed
