The Classic Pet Fountain drinking fountain provides small dogs and cats with fresh and filtered water throughout the day. It promotes your pet’s fluid intake with two selectable water outlets – tap or waterfall spout. Quiet and easy to use, the bowl can be conveniently cleaned in the dishwasher. Equipped with an adjustable water flow and powered by a 12-volt power supply, this cat fountain includes an activated carbon filter, which can be changed monthly to ensure permanently clean water.
