Using your K&H Thermo Kitty Mat is super easy. Just place it indoors where your cat likes to rest. Plug it in, and it'll start working right away. As your cat lies on it, the mat will adjust to your cat's body temperature. Remember, this mat is for indoor use only. When it's time to clean the mat, you can easily remove the cover. Wash it on a gentle cycle with cold water and let it air dry. The mat consumes only 6 watts, so it's energy - efficient. Also, it's MET Listed, which means it meets safety standards. Keep an eye on the room temperature, as the mat will stay 12 to 15 degrees warmer than the room even when your cat isn't on it.
