Sighted a cat that was at least quite similar this evening. Watched me but retreated when I approached. I met the cat at 60 Pearson on the Pearson side; the cat went behind the house and re-emerged at the Kidder driveway of that house, then after hanging out there a while went back to Pearson and vanished behind 47 Pearson.

That whole natural camouflage thing then took over -- no way to stalk a dark grey cat in the dusk, I'm afraid.
