The present invention presents a dual-textured pet food as well as a multi-orifice coextrusion apparatus and method for the use of the multi-orifice coextrusion apparatus for preparing the dual-textured pet food of the invention. The multi-orifice coextrusion apparatus of the present invention feeds a first extruded material through a plurality of inner openings, and a second extruded material through a plurality of outer, annular openings, the inner openings and the annular openings converging to enable formation of a center-filled extrudate at a plurality of extrusion orifices. The present invention also presents a means of configuring the orifices to maintain substantially uniform distribution and volumetric flow of the second extruded material about the first extruded material across the cross section of the orifices.
