The Outdoor Heated Kitty Pad is the cold weather necessity for the 30,000,000 cats that have outdoor access. The thermostatically controlled unit is designed to stay within a cat's body temperature and is perfect for cats that spend time in garages, barns, sheds or outdoor porches and patios. Veterinarians also recommend this pad for therapeutic post-surgery convalescence and to comfort older and arthritic cats. Its ABS waterproof plastic construction makes it both durable and easy to clean. The 12 1/2 in. x 18 1/2 in. pad uses only 40 watts, has 5 1/2' steel wrapped cord and a limited one-year warranty. Comes with a Free Cover.
