PRODUCT DETAIL: Product use note: Feeders and drinkers will always produce water and food when they are turned on. When pets eat, turn on the feeder and water dispenser by rotating the bottle. After the pet has finished eating, turn off the feeder and water dispenser by rotating the bottle again to prevent food and water from overflowing. This product is designed to make it easier for us to add food outside the cage and secure the pet bowl to prevent it from being knocked over by pets.
