When I was a starving undergraduate, a chum of mine was doing graduate work on Western squirrels. Sadly, he was required to trap and kill them, to remove one bit of them for study and to discard the rest. This seemed a terrible waste and so we took numerous frozen squirrel carcasses from him and learned to cook them. I haven't tasted squirrel since I was an undergraduate but, if memory serves, it was pretty good.
