Birch is pretty affectionate, as far as cats go. He likes to lie next to me (or sometimes in my lap, but only when he wants to, not if I put him there) and will generally submit to being picked up/cuddled/smooched for a few moments before he starts to struggle.
Last night, however, was unprecedented: he fell asleep with the side of his face literally mashed against my mouth and nose.
I was flattered, and his face smelled okay, so I let him remain there. He stayed for hours. It was epic.
