Boil squirrel until cooked through and pull from bone (3-4 hours on high in a crock pot does well too). Meanwhile, soften cream cheese to room temperature. Mix squirrel, cream cheese, buffalo sauce, shredded mozzarella & cheddar. Line an 8 x 8 pan with wax paper. Spread mixture evenly into pan and freeze for 1 hour. Lift frozen mixture from pan and slice into sticks. Set up 3 separate bowls (one with a cup of flour, one with a beaten egg, and one with a mixture of the bread crumbs and ranch seasoning). Roll each stick in flour, then in the beaten egg, then in the bread crumb mixture. Deep fry at 370 degrees for 30-60 seconds or until golden brown. Dip in blue cheese or ranch dressing if desired.
