Does it heat or cool? Actually, it does both, and it's called "Heat-Shift" technology. One side of the mat has cooling crystals and the other side, a soct cusion of memory foam. Body heat is drawn into the crystals, turing them into a gel-like substance that cools your pet. No refrigeration or wetting needed! Flip the pad over when it gets chilly and the super soft visco-elastic foam will keep them warm.
