Insulated tub made of strong plastic that can withstand great stress. The insulation keeps the water cool in the summer. Can be filled with temperate water in winter, which then stays frost-free longer. Can be supplemented with a lid to further extend the time the water remains frost-free. Handles in the tub facilitate transport and handling of the tub. Scales on the inside of the tub make it easy to determine how much the animals drank.
