Cheerble Pumpless Cat Water Fountain Wireless Pet Fountain, Battery Operated, 2L/67oz E1+ Automatic Cat Water Dispenser MagDrive™ Technology with Stainless Steel Tray Water fountain has no traditional pump which makes it much easier to keep clean. This pump comes with 6 Cheerble replacement filters. Has worked great for my senior cat, but he now lays down to drink due to osteoarthritis, so we're back to the classic bowl🥹☺️
