The Petkit Eversweet is an innovative water fountain for dogs and cats, designed to ensure your pets always have access to clean and fresh water. Equipped with a 3-stage carbon filtration system, this fountain effectively filters harmful chemicals and impurities from the water, providing safe hydration. It includes a filter replacement reminder that flashes on the front of the device and a blue LED light that automatically illuminates when water levels are low, alerting you to the need to refill. Water levels are easily visible through the transparent acrylic chamber.
