Healthy Material and Easy to Clean: The Tritone Cat Water Fountain is crafted from high-quality natural ceramic, making it eco-friendly and easy to clean. It's a superior choice compared to plastic fountains. Dual Filtration System: The mechanical filtration with a foam filter surrounds the pump to prevent pet hair and debris from entering the tank.
