Abstract: Provided is a pet food for easily removing dental calculus and plaque from teeth and gums of a pet by inducing active masticatory action of the pet. In the pet food, through-holes having various sectional shapes are formed at regular or irregular intervals through a body that is edible by the pet. Wrinkled portions (or screw threads) are longitudinally or transversely formed in the inner circumferential surface of the through-hole. Alternatively, one or more protrusion units protrude toward the longitudinal central axis of the through-hole from the inner circumferential surface of the through-hole, or protrude from the inner circumferential surface of the through hole so as to form a helical ridge.
