Here's a photo from three weeks ago when I'd just returned from having had a haircut, there being a much greater quantity of chin-hair than that on top:-
And here's my two co-residents, Patchie (12 years old) and Blackso (actually Blackso II), age and owner unknown to me. though he's clearly an adult. He seems to have decided to move in, sleeping and taking his eats here - and, much to Patchie's evident displeasure, has established himself as the dominant one, having taken over the kitchen where Patchie will now no longer go. Unfortunately Blackso's been drinking a lot of water daily, a worrying sign.
I'll give them both a pat and gentle strokes from all you many cat-lovers out there.
