More Practical 2 In 1 Design: You no longer need to prepare multiple cat food dispensers, which are both wasteful of space and hard to dump! This automatic cat feeder functions as both a cat water dispenser, it can hold 4/5 gallons of dry cat food and 1/5 gallon of water for cats or small dogs. Safer for Pets: This cat food and water dispenser set uses the latest gravity automatic drip technology, which automatically stops when the food and water levels reach a predetermined location. The cat food dispenser doesn't need to be connected to a power source, it has the added safety and flexibility to be used indoors or on decks without outlets. Continuous Cleanliness and Hygiene: The floating plate inside the water bowl prevents wetting the cat's fur. The height of the cat gravity water bowl is higher than the food dispenser, so you don't have to worry about food falling into the water and affecting its cleanliness.
