Hobbes visibly pouts. I have no way to 'splain it...just that she moves off a few feet, looks at me with slightly closed eyes and then looks away and switches her tail. At that point, nothing else moves but her ears, and unless I pick her up and apologize, she stays that way...for hours.
I was lamenting my luck with the opposite sex one day, and made the mistake of saying it in front of my [then] cat.
What did I say?
"I wish I had a grilfriend who lived nearby."* said in 1992
My cat, Mimi, snaps her head around, howls this tortured and hurt "MWOWM" (muh-wow-m) and then takes off.
She wouldn't 'talk' to me for two weeks.
