Lamb patties contain the whole animal except the head, hide, bladder and large intestine (manure), hooves, horns (if any). We do not use non-edible bones 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, kidneys and the tongue. On average, patties are composed of 66% muscle meat, 7% bone, 10% organs, 7% blood and 10% fat. Other than the vegetables and fruit in our dinners we DO NOT add anything to our diet patties.
