PROBLEM TO BE SOLVED: To provide an apparatus for automatically measuring the amount of feeding capable of easily measuring the body weight of an experimental small animal and capable of controlling or measuring the daily amount of feeding. SOLUTION: The apparatus has a cage 44 to house a small animal therein, and a feed box 40 furnished adjacently to the cage 44 and having a feeding port 42 communicating with the cage 44 and serving as an opening through which the small animal's head is insertable. This apparatus is also equipped with a feed weight sensor 30 placed with the feed box 40 and functioning to sense the total weight of the feed box 40 and feed 84 therein. Further, this apparatus is equipped with a shutter 46 capable of opening/closing the feeding port 42, a shutter-driving unit 50 for opening/closing the shutter 46, and a microcomputer 68 as a control unit functioning to process signals from the sensor 30 and control the shutter 46's opening/closing by the shutter-driving unit 50.
