Squirrel stew is excellent. Check a few recipes on line. Simmer for hours with veggies. Squirrels are hard to skin however so check out the proper technique.
I might add that young groundhogs (some call them woodchucks) are also excellent meat.
I guess that depends on where you are. I can field strip a local tree rat in about 2 minutes, ready for the frying pan.
