It looks like Sammy suffered a bit of a wound on the crown of his head. No blood and nothing opened. It’s scarcely worth noticing. It looks like a tiny dark crack where there should be gray fur. I probably would not be mentioning it, except that it brings images of Willy to mind. As Sammy’s wound looks just similar enough to bring Willy to mind. It’s much smaller than anything Willy had, though. I wonder if a bird paid Sammy back. It can look like a beak-peck.
