The Pet Marvel cat water fountain is a cordless, battery-operated device that offers great convenience. With a 120-day long-lasting rechargeable battery, it can be placed anywhere without the need for a nearby outlet. An automatic motion sensor activates the water flow when a cat approaches, optimizing energy use. Its water-and-electricity-separation design guarantees safety. A high-filtration system provides clean drinking water, and the quiet pump ensures a peaceful environment. The large 2.5L capacity reduces refilling frequency, making it an ideal choice for pet owners seeking a hassle-free, safe, and cat-friendly water-providing solution.
