If your pet spends time outside in the winter, this is a cold weather necessity. Now you can make sure your pet always has access to drinkable water all winter long with a Thermal Bowl. The Thermal Bowl will keep your dog's (or cat's) outdoor water bowl free from ice all fall, winter, and spring down to temperatures to 20 degrees below zero Fahrenheit. But, it uses less electricity than a 30-watt light bulb! The electronics are safely sealed inside the bowl, and the cord is steel wrapped to ensure your pet's safety. It is MET listed in both the US and Canada.
