This is the bowl that keeps a supply of water for a pet chilled all day long, encouraging dogs and cats to stay cool and hydrated. Unlike ice cubes that require frequent replenishing or fountains that require electricity or batteries, this bowl cools water using a removable insert lined with non-toxic gel. After as little as two hours in the freezer (gel changes color when frozen) the insert keeps water chilled well below room temperature for up to eight hours. The durable ABS plastic bowl cleans easily and has a rubber base that prevents sliding. Includes a second insert for use while the other one is chilling. Holds 24 ounces. 2 3/4" H x 10 1/2" diameter.
