This self-warming pet mat provides cozy warmth without electricity, cords, or batteries. The carbon-infused cover absorbs and reflects your pet's body heat to create a naturally warm resting spot. Soft, fluffy fabric offers a comfortable surface for napping, while the noiseless design avoids the crinkle sounds that can disturb anxious pets. Works indoors on floors, sofas, carriers, and window sills, or outdoors in shelters, garages, and porches for community cats. The removable zippered cover is machine washable and dryer safe for easy cleaning. Non-slip bottom keeps the mat in place. Measures 24x18 inches and suits kittens, cats, puppies, and small dogs up to 25 pounds. Also ideal for aging, recovering, or arthritic pets who benefit from extra warmth.
