Radiant Warming Insert

The patented Radiant Warming Inserts are designed for use with the Four Paws K-9 Keeper Sleepers.  The Insert works naturally with your pet's body heat by reflecting the heat directly back into the sleeper bed.  No microwaving or electricity is needed!   NASA space blanket technology soothes pets with orthopedic or arthritic problems or just keeps them warm during the winter.
