We had a dark grey cat (Norfolk bred, very Norfolk in character) called Tom. He was reserved, domineering, voluptuous — much as I imagine Tiber to be. When he was middle-aged he gave up nocturnal prowlings and slept on my bed, against my feet. One evening I was reading in bed when I became aware that Tom was staring at me. I put down my book, said nothing, watched. Slowly, with a look of intense concentration, he got up and advanced on me, like Tarquin with ravishing strides, poised himself, put out a front paw, and stroked my cheek as I used to stroke his chops. A human caress from a cat. I felt very meagre and ill-educated that I could not purr. It had never occurred to me that their furry love develops from what was shown them as kittens.
