Unitized animal food system product

Abstract

A simultaneously compacted, shaped, molded and unitized, self-contained, unit-integral, chew-resistant animal food system product containing animal food and structure-supporting fibers, preferably in a fibrous form, in an amount sufficient to make said product chew-resistant, self-contained and unit-integral and to enable it to be and remain in its compacted, shaped and molded form. The product contains sufficient structure-supporting fibers to yield a chew-resistant product. The structure-supporting fibers are animal safely digestible structure-supporting fibers, such as collagen, animal safely indigestible structure-supporting fibers, such as cellulosic materials, or a mixture of animal safely digestible structure-supporting fibers and animal safely indigestible structure-supporting fibers, such as a mixture of collagen and cellulosic materials. Illustrative food components are those animal foods currently used and known and are preferably in a dry, shelf-stable form such as dried meats, dried fish, fish meal, fish flour, cereals, fruits, etc., with or without food additives or supplements such as vitamins, minerals, medicinals, etc., for example chemicals, enzymes, etc., capable of removing plaque or tartar from the animal's teeth, etc. Sufficient structure-supporting fibers are mixed with the basic food components, the collagen thereof being preferably derived from animal skins or hides preferably in a fibrous form, and the structure-supporting fibers are capable of binding the food into the unitized chew-resistant product. Collagen, preferably derived from animal skins, is the preferred fiber. Also within the scope of this invention is a simultaneously compacted, shaped, molded and unitized, self-contained, unit-integral, chew-resistant multilayer animal food system product containing at least one chew-resistant layer and at least one lesser or non-chew-resistant layer, wherein the chew-resistance of said layers is primarily controlled or varied by the relative presence or absence of structure-supporting fibers incorporated into the particular layer of food components, as aforesaid, prior to contacting, said structure-supporting fibers being as aforesaid.
