ENVIRONMENTALLY FRIENDLY & INNOVATIVE: Unlike other heating pads, ours is environmentally friendly and innovative. Our self-heating blanket uses the latest aluminum foil technology, self-heating, plug-in-free, energy-saving, and safe. As long as your pet lies on it, the mat can keep them warm at a constant temperature. To test it, place your hand on the self-heating pad and you will feel warm in 10 seconds. 5-LAYER DESIGN: This pet heating mat features a 5-layer structure: super soft fluff on the surface, heat-retaining cotton flannel, heat-storing aluminum foil in the middle, warm wool cloth, and non-slip Oxford cloth on the bottom. The surface is soft and warm to protect your pet. The bottom is non-slip and convenient to use. WASHABLE & DURABLE: The self-heating pad is machine washable or hand washable and reusable. Pet pads get dirty easily, so it's important that they're easy to clean and durable. At the same time, they're foldable, easy to store, and carry. NON-SLIP & LEAK-PROOF: The bottom of our pet mat is waterproof to prevent pet urine from dripping onto the floor. Suitable for all your large or small dogs and cats. Colors: Gray; Sizes: L: 90 x 60 cm SUITABLE FOR ALL OCCASIONS: Handmade, exquisite and durable, this blanket retains temperature and keeps pets warm anytime, anywhere. Suitable for outdoor use, travel, camping, car seats, pet nests, pet cages, sofas, beds, floors, and more. It can also be used as a seat cushion or foot warmer to keep you warm in winter.
