I do the crock pot thing too. When the meat comes off the bones get them out of there and the meat back in. In my case, I toss in egg noodles and make squirrel and noodles. Yum.
Pan fried squirrel is great, especially with gravy, but they are always a roll of the dice on how tough they might be. I've gotten to just pretty much erring on the side of squirrel and noodles every time.
Small immature Greys are fry-able. Everything else needs an hour and 20 minutes in boiling water. Or 15 minutes at 10# of pressure in a pressure cooker.
