Treat your pet to a warm and cozy rest on a FurHaven ThermapNAP™ Self-Warming Pet Blanket. The ThermaNAP™ Self-Warming Mat works without electricity to build up your pet's natural warmth while they rest. The inner self-warming technology captures your pet's body heat and reflects their warmth back to them using a layer of reflective (space blanket) material and a layer of insulating polyester fiber batting core. Its lightweight, portable design makes the ThermaNAP™ Self-Warming Blanket great for traveling to ensure your pet stays comfortable and warm wherever you go! Snuggly-soft and oh-so-comfy plush velvet sleep surface is soft on noses and paws and is available in three sizes and four stylish colors so you can find the perfect match for your furry friend. The Self-Warming Mat is machine washable for easy cleaning so you can keep your pet's bed fresh.
