Cover the pan and allow the cardboard pieces to soak in the reserved bacon fat overnight at room temperature. By the next morning the cardboard should have soaked up most of the bacon fat. If there is any bacon fat left in the pan, grease a cookie sheet with it. If not, corn oil will be sufficient to lubricate the cookie sheet. For an extra special touch, you can coat the cookie sheet with some cornmeal.
Corn is a rich source of Omega Fatty Acids.
Put the cardboard pieces in the bag and shake well. Remove the cardboard pieces with a slotted spoon and spread on your greased cookie sheet. Bake for 40 minutes or until well browned. This homemade cat food will last at least nine months if kept tightly sealed. Because cats enjoy having constant access to food, keep a food bowl full of this healthy homemade food throughout the day.
