My 6 month old kitten seems to have this routine where he climbs on to my chest and meows in my face before plopping down and kneading and licking my arm particularly where my arm folds. He only does it in this place on this arm and no where else he seems so happy and content when he does it and I love it I've never heard a kitten purr so loud I'm just genuinely curious as to why he does it so regularly too!
