The Thermo Kitty Mat is a 12.5” X 25” heated sleeping mat. The 6-watt dual thermostat heater is buried beneath soft foam to make a comfortable area for cats or toy breed dogs. The surface of the bed will remain 12 to 15 degrees above ambient air temperature and warm to a wonderful 102 degrees when in use by the pet. The cover is made of plush faux lambskin and is removable for washing and the heater is removable for use as an unheated bed. Thermo Kitty Mat is UL and CUL listed and is recommended for indoor use.
