This invention generally relates to animal feeders, an animal feeding monitor and a method of training an animal to use a feeder. An animal feeder may have a housing comprising an aperture for a food bowl and having a door for covering the aperture, wherein the door is movable between an open position and a closed position, the feeder comprising a door mechanism to control movement of the door over the aperture to open and close the door, wherein the feeder comprises a sensor to detect when an animal has moved away from the aperture, and the feeder has a training mode wherein the door mechanism controls the door to move towards the closed position to cover a portion of the aperture in response to a said detection and responds to one or more later said detections by controlling the door to move towards the closed position to cover a portion of the aperture larger than the preceding said portion thereby to train the animal in how to use the feeder.
