The Pet Bed warmer has dual thermostats and is designed to warm to your pet's normal body temperature of 102°F when he/she lies on the bed. The surface of the bed that contains the Pet Bed Warmer will be about 15°F above ambient air temperature until the pet lies on the bed. Then it will warm to about 102°F. The surface temperature depends on how much padding is on the pet bed. If there is a lot of padding, it will be cooler. If the padding is thinner, the surface will be warmer.
