Wolves aren’t renewable… Are they?
What’s your playstyle? Do you not raid cities and houses? There’s plenty of food in them, virtually endless amounts. If you want pure renewable, then you would farm or fish. Farming requires seeds, though, so you’d have to get them first… Foraging is an option, too. Examine bushes. Sometimes they yield cooking ingredients. There are also strawberry bushes, apple trees and such, but you’ll have to wait for summer or autumn before they have any fruit. Then it becomes a matter of preserving them.
