The Automatic Pet Feeder and Waterer Dispenser Set is a complete feeding and watering solution for your pet. With a natural gravity supply system, this set does not require any electricity to operate. Made of food-grade plastic material, this set is 100% recyclable and durable. The set includes one waterer with a gallon capacity and two feeders with capacities of 3.8 liters each. The waterer has a spring valve that prevents large amounts of water leakage after tipping over. The non-skid rubber feet provide a secure placement for the waterer. The feeders can be split for easy cleaning. The set also includes customer service if you have any problems with your order.
