The device for supplying the pellet includes: a body part having a fixed hole, through which a feed is discharged, in a bottom surface of an inner space in which the feed having the form of the pellet is stored; a rotation plate part disposed in the inner space and having one or more rotation holes, the rotation plate part rotating so that, when the rotation holes rotate, the pellet feed seated in each of the rotation holes is discharged through the fixed hole from a discharge position at which the rotation hole and the fixed hole meet each other; and a rotation plate driving part rotating the rotation plate part. Therefore, the feed may be supplied in the form of the pellet so that the pet sufficiently chews the feed to help the digestion of the pet.
