This self-warming crate pad uses material that captures and radiates your pet's body heat for a cozy resting spot. The design features a soft microfleece top with a thin plush polyester fill for comfort and a non-slip bottom for stability. Designed with corner slits for a perfect fit in pet crates, this pad can also be used as a stand-alone bed. It is lightweight for easy travel and is machine washable for simple maintenance.
