My two cats always followed me into the bathroom, and either sat there staring at me, or rubbing their faces up against the cabinet. As soon as I headed to bed, they'd be up there too. One loved to have his belly rubbed, and would lay on his back so I could do that. Whenever I stopped, he'd put his paw on my hand which was his way of telling me to keep doing it.
Big cat will lie there in ecstasy for as long as you are willing to rub his tummy and give you the sad eyes when you stop.
