Fresh water, all day, without you refilling it every few hours. The Automatic Water Bowl uses UV sterilization and a built-in filter to keep the water clean and slime-free — because pets drink more when the water smells and tastes clean. USB-charged, sensor-activated, and smart enough to run without draining the battery. Designed for cats, dogs, and multi-pet households who deserve better than a stagnant bowl. Keep their water fresher longer with this smart pet water fountain.
