Features : Self-heating Technology : Our pet mat is designed with advanced aluminum foil insulation, which enables self-heating without the need for electricity, wires, or plugs, ensuring energy efficiency and safety. The aluminum foil's heat conductivity, when combined with the insulation cotton, creates a heat reflection effect. This effect helps to maintain the pet's body temperature, providing warmth and protection against the cold. 5-Layer Construction : The self-heating pet mat is crafted with a 5-layer structure for optimal comfort and functionality: Top Layer : Super soft fluff for a comfortable surface. Middle Layers : Flannel insulation cotton and a heat-preserving aluminum foil for effective temperature retention. Bottom Layer : Anti-slip epoxy oxford cloth to prevent the mat from moving and to protect against bacterial growth. Additional Features : The insulation fluff is designed to be durable, resisting shedding and fading. Non-slip and Leak-proof Design : The underside of the mat is treated with waterproof epoxy, offering a non-slip and leak-proof surface. This design is particularly useful for preventing the spread of pet urine, ensuring cleanliness. The mat's dimensions of 50 70CM (19.7 27.5 inches) accommodate pets of various sizes, from small to large. Durable Quality : The mat features a 4-side hand-stitched edging process, enhancing its durability and preventing fraying. The 5-layer structure is reinforced with high-frequency anti-pressure technology to ensure that the heat is securely retained. This makes the mat suitable for a wide range of applications, including pet nests, cages, car seats, sofas, beds, and other surfaces. Easy Care and Portability : The self-heating pad is easy to clean, with machine washable and hand washable options, allowing for repeated use. Its compact design makes it portable and convenient for storage.
