Lost me there. I don't know about you, but I have no more or less problem with rats than with squirrels. What's wrong with rats? Depends what they eat, of course -- I don't want sewer/trash rats. But rats fattened for a week or two on corn and bread and good things, what's wrong with that? My problem is killing the suckers. Birds are nothing to me -- louse-ridden overrated horrors. Mammals, that's different.....
Of all game, squirrels seem to be the most controversial. Friend Wife, for instance, thinks of them as rats that live in trees, and won’t go near them.
All the ones you listed are extremely good meat. Anything in the deer family will be much leaner than beef, and also more flavorful in my opinion. I grew up hunting deer, elk, and the like, but my favorite wild meat is caribou. My father killed one about 15 years ago on the north slope of Alaska. It was absolutely fantastic.Hmmmm...I've never eaten squirrel. I would like to try it some day. I have had buffalo and venison and elk a number of times. Elk meat is especially delicious. I feel like I've been very lucky to have had elk hunted by my stepfather and cooked by my mother.
I've heard moose meat is delicious too - that's another one I would like to try some day.
