I agree Moh, for the most part.
One thing I would not recommend to the novice is mushrooms. I have no adversion to them, but I only know enough about them to get myself dead in the wilds. Some are so toxic on spore can kill you if ingested.
And yes, cats, dogs and rats are good when properly prepared
(sautee with butter and garlic).. Also in the survival situation, it is best to cook the food in a pot as a soup or stew rather than broil, bake of fry if possible. It conserves the vitamins into the broth. Perpetual soups: kept over the low fire all the time and added to daily with what is foraged.
Harlington? I guess I missed that. Could you explain?
