K&H Gray Self Warming Crate PadK&H Gray Self Warming Crate Pads are perfect for dogs who need a little extra warmth and owners who shy away from electric pet products. The self-warming pad makes a great dog bed or crate pad and will capture your dog's body heat and radiate back the warmth to the source. The 4 corners are slit to allow the pad to fit many different edges. The adjustable size makes this pad fit into many different crates. The topside of the crate pad is made from soft, inviting micro fleece while the bottom has a non-slip fabric to keep the pad from bunching up in the crate. Simply throw the whole pad in the wash for easy cleaning and care.
