Pets need fresh water daily. This is why many drink out of the toilet. Summer heat also encourages bacterial growth in plastic pet bowls. The Magisso Pet Bowl keeps water and food at ideal cool temperature for hours and limits bacterial contamination – without using any energy or chemicals. Just soak the Magisso Pet Bowl in water for 60 seconds to activate the natural cooling effect for several hours. The Magisso Cooling Ceramics material absorbs the water. Evaporating water cools the vessel and keeps the content fresh for several hours.
