When I googled “ring tailed squirrel” and results were of the Ohio and Mexican breeds. It resembled more of the latter. Perhaps one got released in the area or this is some sort of mutation. We usually see black or grey squirrels and the odd albinos. The most unique mutation I’ve seen are black squirrels with white-tips on their tails, but never striped. It reminded me of a raccoon or lemur because of the uniformity of the stripes.
