Treat your pet to a warm and cozy rest on a FurHaven ThermapNAP™ Self-Warming Pet Mat. Perfectly sized for your feline friend or small canine companion, the ThermaNAP Self-Warming Mat works without electricity to build up natural warmth while they rest. The inner self-warming technology works by capturing your pet's body heat and radiating their warmth back to them using insulating polyester fiber batting core. Its lightweight, portable design makes the ThermaNAP Self-Warming Mat great for traveling to ensure your pet stays comfortable and warm wherever you go! Snuggly-soft and oh-so-comfy plush sleep surface is soft on noses and paws and is available in 6 stylish colors. The self-warming mat is machine washable for easy cleaning so you can keep your pet's bed fresh.
