Designed with the multiple-pet household in mind, the Drinkwell 360 Fountain for Pets gives pet parents the ability to customize their fountain to best accommodate the hydration needs of their precious pets. This can be done using the five interchangeable spout rings that come included with each pet water fountain. Utilizing patented free-falling water streams in conjunction with the same filtration technology as the other Drinkwell dog and cat water fountains, the Drinkwell 360 pet fountain constantly circulates and filters your pet's drinking water. This constant filtration and movement not only helps to inhibit bacteria growth and to continually aerate your pet's drinking water, but it also helps to keep water tasting fresh, making it appealing to your precious pets! It also has a charcoal filter that removes bad tastes and odors along with a submersible pump that provides nearly silent operation. Ideal for households with multiple pets, this innovative pet fountain alleviates the need for pets to wait their turn as its remarkable 360-design allows multiple pets to drink simultaneously. Encourage your pets to stay hydrated by providing them with a fountain that keeps the water clean and tasting fresh. Each fountain includes one replaceable carbon filter.
