Preheat oven to 350 degrees. In a small glass bowl, mash up either, canned tuna, mackerel, cooked chicken or cooked liver and set aside.
In a medium glass bowl, mix all dry ingredients together well. Add egg, oil and chicken stock and mix well. Add meat mixture and blend together well to form a sticky dough.
On a floured surface, pour out dough onto it and knead dough well to get a smooth texture. You may want to add more flour to achieve this.
Use a spoon or your fingers and form dime-sized balls of dough. Place onto a greased cookie sheet. I like to use PAM. Press with a spoon to flatten, you want to keep these treats small so that cat will enjoy.
Bake for 15 to 20 minutes depending on the cooking time of your oven, until golden brown, turn treats once. Let treats cool for at least 20 minutes before giving to cat.
Store extra treats in foil for three days. After three days, place remaining cat treats in an airtight container and store in the freezer for no more that two weeks. Makes up to 70 treats.
NOTE: If you do not wish to purchase the Wheat Germ, you may substitute rolled oats (uncooked oatmeal) instead. If you do not wish to purchase the Brewers Yeast you may substitute ¼ tps. Garlic powder instead.
