He’ll come running , head butt you and plop over on to his side, wanting his belly rubbed.
I got adopted by a Norwegian Forest Cat too. I think he must have been someone’s pet then abandoned out here in the wilderness, because he has impeccable manners inside; always asks permission to jump up on furniture or lap, and doesn’t get into things. Comes when I whistle. The Bridge Over the River Kwai theme (Colonel Bogey March) is his favorite tune. He doesn’t like anyone but me. Does that headbutting thing, but prefers his head and chin scratched to a belly rub.
He was a good hunter and a fearless fighter, and ranged wide, only coming in for dinner and a nap... until he went to fight the dang coyotes too many times. Got hurt from that a few times, and the last time was one too many; he mostly stays inside or nearby these days.
