The method of producing a dry expanded pet food by extrusion cooking of a blended mixture of proteinaceous material slurry and dry farinaceous material. The proteinaceous material slurry is adjusted to have a fat content of at least 25%, is elevated to a temperature in the range of 150 DEG to 175 DEG F, and then homogenized to reduce particle size and distribute the fat content uniformly through the mixture. Farinaceous materials constituting an appropriate dried ground mix of cereals, vitamins, minerals, and preservatives are added to the proteinaceous slurry. Following the extrusion cooking step, which results in the expansion of the cooked material, the cooked material is dried to a water content of from 7% to 15%, resulting in a microbiologically stable, appetizing animal food.
