KandH Self-Warming Crate Pads are available in 6 different sizes and 3 colors. 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 microfleece while the bottom has a “stay pet” 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.
