FOUNTAIN FOR DOGS AND CATS: this fountain improves the hydration of animals and thus helps reduce kidney problems. ADJUSTABLE FLOW: The Cascading Water Jet system oxygenates the water, encouraging animals to drink more. NEARLY SILENT OPERATION: This fountain has a submersible pump which makes it virtually silent. ANTIBACTERIAL FILTER: The activated carbon filter is made from coconut shell and retains odors, bad tastes and bacteria. The water stays fresh thanks to the pre-filter which retains hair, debris and pet food left in the water. NON-SLIP: Rubber feet prevent slipping. In addition, the landing ramp reduces splashing caused by the waterfall. WARRANTY: The Drinkwell Pet Fountain Facilitating temperature regulation and fat metabolism
