Abstract: An animal feeder constructed of an open top feed bin with a bumper secured to the top edge of the bin. The bumper has a wide rounded or beveled top edge to discourage animals from chewing on it. A horizontal slot in the side of the bumper is provided to admit an open work panel to be inserted through the slot and into the open top of the bin. Once within the bin, the panel rest on the feed contained within the bin. Openings provided with the panel allow an animal to access the feed. The openings can be custom sized. The panel can be removed from the bin via the slot so that the bin can be refilled with feed. An optional cover can be attached to the top of the bumper to protect the feed from the weather or to prevent access to the feed by animals.
