Minor modifications of a commercially available food cup permit automatic recording of a rat's contacts with common dry food. It is thus possible to measure the frequency and duration of the "meals" that rats take over extended periods of time, and, in conjunction with existing devices for measuring drinking, to record contingencies between eating and drinking.
