Been seeing her around, she moves ok but something is real wrong. She's by herself a lot. The pic doesn't show how thin she is, you can count her ribs easily.
She might just be so old that her teeth are too worn to effectively grind acorns & woody browse anymore. The downward sloped hip and small ear : head ratio looks like an old deer to me. Young deer have humped hips and dumbo ears. My guess is that girl is ancient.
