Drinkwell?360 was designed with the multiple pet household in mind, giving owners the ability to customize their fountain with the five interchangeable spout rings included with each fountain. Pets no longer have to wait their turn for a quick lap of water; they now can each have their own fresh flowing stream of water from any angle. Utilizing the same filtration technology as the other Drinkwell?Fountains, the Drinkwell?360 constantly circulates the water which inhibits bacteria growth, keeping the water tasting fresh and appealing to pets!
