Abstract: An animal feeder is provided which has a bin portion for storing feed and a trough portion. The two portions have mating ribs and grooves forming a fluted joint which when used with a suitable adhesive agent bonds the two portions together. Located in the lower end of the bin portion is a flow passageway communicating with the trough portion and having a dispensing opening through which the feed is dispensed into the trough portion. The flow of feed is controlled by a variable gate positioned so as to regulate the size of the dispensing opening. The size of the opening, distance of the top of the opening from the trough, and a vertical rib positioned within the trough portion which circumscribes the dispensing opening and acts as a dam, cooperate so as to limit the amount of undisturbed feed in the trough position. The feeder is designed to mate with a hanger therefor to allow simple and quick mounting of the feeder to a fixed structure.
