Don’t forget mouse traps and other ways of keeping them safe from vermin.
Urban pigeons and rats are definitely NOT a safe food. They’re full of chemical pollution that you can’t cook out, and probably more than a few diseases which you might also catch. It beats starving to death, but you should consider basically anything else, including boiling your (vegetable tanned) leather belts and shoes.
Pigeons are actually a domesticated animal that used to be bred for (among other things) food. So you re-domesticate a few of them, and then eat their offspring which you feed household scraps.
You might also save on heating in the winter by having larger cattle in your house and sleeping on a loft above them.
Ah fuck, I just threw a dead mouse away a couple weeks ago. I’m gonna be kicked out of the community for wasting food soon. 3 people could’ve ate with that.
