Here's one that I use:

Cut the squirrel into pieces and then brown the pieces in oil in a fry pan, but don't cook through. Load up a crockpot with squirrel pieces, veggies (I usually use potatoes, carrots, onion and celery), add a clove or two of garlic, a can of cream of whatever soup (mushroom is the best, but chicken or broccoli or whatever is good too) and a half a can of milk or water. Cook on low for at least 8 hours. I usually do this when I have to work all day and I've cooked in the crockpot for as long as 12-14 hours.

Then remove the squirrel pieces which will be really hard because they are so tender they fall apart. Discard the bone pieces and add the meat back to the crockpot. Serve over biscuits or mashed potatoes or noodles. Yummy!!!!!
