You just stated the obvious Lee, except no one, including me, has ever stated it...and that's about 27 years of my life.
I have an unusual spiritual connection with cats. Nero's just the latest. As I just PM'd someone, Nero had this settled fr when I fostered him for a weekend in mid-Sep. He settled in on my bed, fell asleep either against my face or spooning (I just woke up and there he'd be). When I've been down he's more than once planted himself on the adjacent pillow and rested a large paw on my hand or arm and snoozed off.
Put another way, it was already settled four months ago even as I was unsettled.
