K&H's Thermal-Bowl heated pet bowl keeps your outdoor pet's water from freezing, even in sub-zero temperatures. These bowls are thermostatically-controlled, so they only operate when necessary, using just 12-25 watts of electricity—which keeps those electric bills down. The electrical elements are concealed inside the bowl, and the 5.5-ft. cord is steel wrapped to prevent chewing and abrasion damage. Spill-resistant shape. Plastic bowls are heavy duty plastic. Could also be used for barn cats and other small animals.All come with K&H's one-year limited warranty, and are MET-listed.
