Sounds like he is turning into our old Lucky!
When I fostered, he would always come and investigate new young cats. He would do the "in my day" thing, I'm sure - though he probably told them
"In my day we didn't have this waitress service - Good Lord, no! * stops for swig of water* You young things these days want to be hand fed!! Why, wed go out nd bag a brace of bluetit at dawn, and be back for a hearty mouse breakfeast, before we had even thought about what the humands offered"
then, he would bat a catnip mouse around as if he was a kitten himself. When the kitten came to join in the game, Lucky would remember he was a very old man, sit down on the catnip mouse and have not 40 but more like 400 winks.
And if the kittens became too active and bounced all over them, he would pick them up and drop them beside the kitten pen, then look at me as if to say "Put away time now, Mum"
