A compact, animal-operated animal feeder is disclosed in which the feeder housing has a pair of foldable doors mounted over a feed opening and latched in a closed position. The doors can be unlatched by the animal, which carries a latch release device about its neck, and the natural tendency of the animal to push toward the feed will fold the doors laterally to an open position permitting access to food inside the feeder. A magnetic latch release assembly in which a plurality of permanent magnets are arranged in an array to provide a key for release of a latch having correspondingly arranged magnets is also disclosed. A compound door including a magnetically releasable latch assembly is also disclosed.
