ABSTRACT:
A laboratory animal controlled access feeder has a reservoir or hopper from which feed falls into a feed tray. The hopper is completely covered and access to the feed tray is limited to a small circular opening in order to mitigate the potential for contamination of the feed. The opening in the feed tray cover has a collar which extends downward to mitigate spillage of feed from the feed tray. Compaction of powder or granular feeds is substantially eliminated via a rake which is attached to the loosely attached lid of the feed tray and thus moves back and forth through the feed as the animal eats, thus continuously manipulating the feed and preventing compaction thereof.
