2.0 Upgraded double foil design: The classic self-warming cat bed has been improved with a second heat-reflecting foil layer and thicker insulation. The result is a more comfortable warmth that lasts longer – perfect for cold cats or older pets. Self-warming without electricity: Unlike electric heating beds, no cords or outlets are required. Two layers of thermal foil under the soft fleece fabric capture and reflect your pet's own body heat for natural heat retention. Soft fleece & non-slip bottom: The extra soft fleece top provides high comfort and retains warmth even on cold days. The non-slip bottom ensures the bed stays firmly on wooden or tiled floors. Removable & washable cover: The zippered cover can be easily removed and machine washed. Just remove the foil insert before washing. Easy cleaning keeps the bed fresh all year round. Versatile & pet-friendly: Suitable for both indoor and outdoor use – on the sofa, floor, in the cage or cat/dog house. The size 40×50 cm makes it ideal for cats, kittens and small dogs. A perfect warming bed for all your favorite places.
