Puree the bones and meat in a food processor. Blend or process the mixture until it can be gathered together into a ball. Cut into shapes with cookie cutters. Cooking stores have a selection of cutters that often includes a bone-shaped cutter. I also have a fireplug-shaped cutter.
Place biscuits onto a lightly greased cookie sheet.
Bake until firm to the touch. Another test is to drop one on the countertop and see if it has a brittle sound. When cooled, store in an airtight container. Makes about two dozen medium-sized bones. Grated bits of leftover cheese can be kneaded into the moistened mixture.
