Designed with multiple pets in mind, the PetSafe Drinkwell 360 Drink Fountain gives pet owners the ability to customize their fountain with five interchangeable spout rings to change the fountain from one fresh stream of water to five. The 360 Fountain uses the same filtration technology as the other Drinkwell Fountains, with the addition of a submersible pump for nearly silent operation. This fountain weighs only 4 lbs., holds 128 ounces of water, has an adjustable flow control, and features rubber feet to prevent sliding. The receiving ramp reduces the splash made by the falling water. The 360 Fountain uses a replaceable charcoal filter to eliminate bacteria, stagnant tastes, and odors. Made by Drinkwell, a veterinarian developed product line and the only fountain line with a Free-Falling stream of water. Perfect for both cats and dogs. Why use a pet drinking fountain? Moving water is much fresher than stagnant water, and in nature animals are drawn to moving water by instinct. The movement of water draws oxygen from the air into the water keeping the water cleaner and tasting better. All Drinkwell Pet Fountains filter and aerate the water by keeping it moving, which keeps it much fresher than standing bowl water. By continuously circulating the water, the amount of saliva found in the bowl is reduced and bacteria growth is inhibited. A charcoal filter helps remove bad tastes and odors, making the water taste fresher and more desirable to pets. Drinkwell Pet Fountains are veterinarian designed and recommended by vet urinary specialists, and are especially beneficial for pets with kidney or urinary tract diseases. Lower Urinary Tract Disease is the #1 cat illness, and staying hydrated helps support kidney function and prevent crystal formation and obstructions that lead to Acute Renal Failure. Additionally, it helps keep cats off counters and out of sinks in search of dripping faucets.
