Get the black plastic heat pad it's amazing and will save your pet from the brutal cold.
                    NOTE: I NEVER Use the Fleece Pad EVER because it takes away from the heat. The pet
                    Should lay directly on the heat source because they stay much warmer in the winter.
                    I have used these for many years for outdoor rescue cats. They stay warm to just their
                    Body temp but never too warm. They are amazing!
                    The black plastic one stays warm always while plugged in the soft grey one does not.
                    The soft grey one goes back to being cold once the pets gets off & has to warm back up when the pet gets back on it which will be uncomfortable.
                    Put the heat pad inside of a dog or cat house that is waterproof.
                    The pets will be very relieved & grateful for this to help them live
                    Through the winter.
