Roy-L-Heat Calf Warmer
Brand: Smucker Manufacturing
The Roy-L-Heat Animal Warmer helps you save hypothermic calves and lambs. The box is made of tough, high-density polyethylene. Its interior size provides adequate space for calves to lie down and to stand up. Opposite the heater is a rubber "head boot" which permits the animal to breathe outside air when desired, yet holds the warm air in at all times. The "attic vent" allows excess moisture to escape.
