It's no secret that many cats prefer running water for drinking. Automatic water dispensers are a must for cats whose owners work long hours, to ensure fresh water at all times. These are the best, in my opinion, among those I've researched, and I personally have used one of each brand for my cats. It should be noted that all automatic pet fountains require regular cleaning and replenishing of water in order to continue running properly.
Drinkwell Platinum Pet Fountain
Petmate Fresh Flow Purifying Pet Fountain
This fountain is remarkably quiet while delivering a continuous flow of fresh water, filtered through charcoal for purity. The self-contained unit holds a 50-oz. supply of water and is attractive as well as functional. Like all automatic water dispensers, it is extremely important to regularly clean the unit, and replace the filter as directed.Original Drinkwell Pet Fountain
The Drinkwell Pet Fountain features a flow rate control knob and reusable filter. The self-contained unit holds about six cups of water, and an optional reservoir doubles that capacity. If your cats love running water, the trickling effect will attract them.Cat It Fountain
Drinkwell 360 Water Fountain for Pets
The Drinkwell 360 brings a whole new concept to automatic pet fountains. The water reservoir, which holds one gallon, is concealed under the bowl. A central fountain allows from one to five individual streams of fresh water to flow into the bowl, giving more drinking room for multiple cats.
This product is so new that I haven't yet tested it on my own cats, but if the quality is as good as the Drinkwell Platinum, it promises to be a popular choice.
