Clean and gut the squirrel.

Place the squirrel into the pressure cooker whole, or cut into manageable pieces.  

Add one cup of stock and seal the pressure cooker according to the manufacturer's instructions.

Allow the pressure cooker to come up to 10 pounds pressure (high pressure in an instant pot) and cook for 10 minutes.

Once the cooking time has elapsed, allow the pressure cooker to depressurize naturally.

When the pot is completely depressurized, release the vent and open the pressure cooker.

Remove the meat from the bones and use the pressure cooked squirrel meat as you would any braised squirrel meat, adding it to soups, stews or pot pie.
