1 pound liver, organs, or other meat
2 cups old-fashioned oatmeal
2 cups bran
1/4 cup cooking oil

Preheat oven to 250 degrees F.

Cover meat with cold water and bring to a boil. Immediately lower heat and simmer for 30 minutes. Remove meat from water and let cool; retain water.

When meat is completely cool, chop into 1-inch pieces and grind in food processor, chop in blender, or process through a meat grinder until it is finely ground. Mix ground meat, bran, oatmeal, and oil, adding the cooking water from the meat as necessary to make a thick dough. Avoid using any more liquid than needed to make a dough that is coarse and just wet enough to work with. Shape the dough into flattened balls or little bone shapes and arrange on an oiled baking sheet. Bake for 3 hours. Then, turn off the heat and let the biscuits cool in the oven to ensure they are hard and crunchy.

Let the biscuits air dry for 24 hours and store in an airtight container on the shelf for up to 4 weeks.

NOTE: When making this recipe for cats, shape the biscuits into tiny bits for easy chewing.

HINT: A good idea for getting the meat for this recipe is to save organs from chickens, turkeys, etc. in a plastic bag in the freezer until you have enough to make this yummy treat.
