Only recently I have known that this silent and nicely disquieting black cat is called Elvis.
I had been used to find him roaming over my home, coming from his mysterious abode through the roof.
He didn’t disturb, he simply came in, from the window, took a tour around with the wonderful imperturbable disdainful look which only cat have, occasionally, if he was particularly in friendly mood, approached to sniff at my hand , but obviously he could not tell me his name , which probably he ignored too.
Then once, while I was looking at him, all absorbed in his phlegmatic and noble solitary walks on the roof tiles, a neighbour told me
“Does Elvis come also inside your home?”
So he’s Elvis.
