Whole chicken patties contain the entire bird except the head, feet, feathers, stomach, crops, and intestines. All the bones are grindable so bone content in poultry is higher than in patties made from larger animals.
Pork patties contain the whole animal except the heads, hides, bladder, large intestine (manure) and feet. Non-edible bones are not used as these would not be consumed in nature due to their density. Organs make up approximately 8 to 10 % of the patties - this includes lungs, liver, heart and kidneys.
