The Drinkwell hy-drate Filtration System for Cats is a healthy way to turn your cat,s ordinary water bowl into an automatic water fountain. Designed to fit in your cat's favorite bowl, it remains securely in place with small, powerful suction cups. Fresh water continuously circulates through the hy-drate, stimulating your cat's natural instinct to drink more. Small sediments, like fur and food particles, are trapped in the filter's mesh. Activated carbon filters the water to remove chlorine and odors for a cleaner, better taste. Hy-drate is a fun, affordable way to get your pets to drink more water to help improve their health!
