The invention relates to a device which dispenses pellets when rolled by an animal. The inventive device consists of a central part (1) comprising two cylinders (2 and 3), one of which is nested inside the other, which are equipped with holes (4) of the same size. According to the invention, all or some of the holes in the two cylinders can be aligned more or less completely by manually rotating the external cylinder around the internal cylinder, such that a given number of pellets are released from the central part each time the device is rotated. The invention also comprises two wheels (7), one of which is equipped with a stopper (13).Said two wheels are fixed to the ends of the internal cylinder by means of screwing or gluing and with the aid of a double bayonet (8), and the cylinders are maintained in the selected relative position by a gear tooth system (11 and 12). The invention is particularly suitable for use as a toy, as a means of exercise and to slow down ingestion. |
