The Drinkwell pet fountain is the healthy way to give water to your pet. 3 cup reservoir is standard with filter to clean the water. As the water comes down hitting the bowl it is oxygenated. Plugs into 110 V outlet. This is especially attractive to cats. An additional reservoir is available to attach to it to make adding water a less frequent chore. Why animals love running water: In nature, moving water is much fresher than stagnant water. The movement constantly breaks the surface tension of the water and draws oxygen from the air into the water. This process is called aeration and it makes water more appealing to drink. Pets may be drawn by instinct to moving water for this reason. The DRINKWELL® PET FOUNTAIN filters and aerates continuously moving water to keep it much fresher than standing bowl water. It satisfies the urge for running water and so helps eliminate jumping on counters in search of dripping faucets. Even cats who don't jump on counters to drink from faucets may drink more water using the Fountain. Why is this important? As the veterinarian who created the Fountain for her own cats knows, many cats may not drink as much water as they should. This is one reason the urine becomes so concentrated and predisposes some cats to urinary tract disease. Cats with urinary tract or kidney disease have a critical need for water to support kidney function or prevent crystal formation and obstruction. The DRINKWELL® PET FOUNTAIN is veterinarian designed and recommended by vet urinary specialists. It encourages water intake and proper hydration in healthy cats, and is especially beneficial in cats with kidney or urinary tract disease. AND it discourages jumping on counters in search of dripping faucets!
