this wasn't always the case.
When we lived in Brooklyn, Winky was NOT a "lap cat," much to Mom's regret. Not that he
wasn't affectionate; he'd sit next to us, kiss us, forehead-rub us, nuzzle us, (all of which he
still does) but he never curled up on our laps.
That changed when we moved.
Maybe Winky decided that a change of location called for a change in his routine.
