Abstract: Pet feeding apparatus including a plurality of food-containing tubes, each of which is opened at spaced time intervals by a trap door held closed by the retractable plunger of an electrical relay connected in electrical series to an electrical timer. Upon receiving a signal from the timer, the plunger of the relay is retracted to allow the trap door to open by gravity to dispense pet food in one of the food tubes. Simultaneously, a solenoid valve is opened for a fixed time interval to drain water from a water tank to mix with the pet food and to supply drinking water for the pet.
