  • Patent number: 4185588
    Abstract: A pet feeding apparatus is provided which comprises a box enclosing a feeding space, and openable and closable door means to provide access thereto. The door is spring biased in the open position, while a latch member is adapted to retain the door means in the closed position. Timer means may be set to release the latch member to permit the door means to open at a preset time. The box is attached to an enlarged, flat platform of a length and width larger than the box so that a pet, eating food from the feeding space, normally stands on the platform, and thus cannot accidentally tip or move it while feeding. Also, sound generating means such as a bell may be actuated by the opening door to attract the pet. A novel timer-actuated electrical circuit system may be used to disengage the latch member to open the door.
