Do you want to make dry food for your pets yourself? Here is Peter's recipe, tried out and tasted by himself this morning:
Mill equal amounts of oat, wheat, barley and maize. Add some eggs and lamb lard for the dogs, and pieces of lamb which you do not eat yourself for the cats (in this case, lots of lung). Add water and knead the mixture into a thick dough. Spread the dough on a cooking pan, and use a flat instrument (in this case, a thin piece of wood) to mark the surface into squares of appropriate size for the pet (about 2 centimeters wide for the cats, about four for the dogs). Bake in the oven until it's about dry. Take it out, let it cool down on a cooling rack, then brake the pieces apart. Store in a cool place in a plastic bag. It will keep for a few days.
How much of it to feed to your animal? Well, think of it in terms of weight, not volume. You should feed about the same weight of it as you would otherwise with the dry food which you buy - be aware that this one of your making will be much denser!
Your pets will love it!
