ABSTRACT OF THE DISCLOSURE An expanded pet food product having a moisture content of about 20%-30% by weight and a spongy, compressible cellular structure is made by combining a mix of dry ingred- ients containing farinaceous materials, proteinaceous materials and dry bacteriostatic materials with a blend of liquid ingredients containing an edible acid, a liquified fat or oil, a liquid bacteriostatic agent and water, and passing said admixture into an expander where it is subjected to mechanical work, shear, heat and pressure. The hot admixture is extruded through a die plate into a zone of lower pressure to cause the extrudate to expand. As the extrudate passes through the die plate it is cut into particles of desired length and promptly contacted with a water spray to reduce its temperature and control the amount of moisture loss from the particles. The cooled extrudate particles are coated first with an edible fat or oil and then with a solution containing an antimycotic, water and flavoring material. The thus coated product is then packaged.
