My cat Casey LOVES to eat. With 3 adults in the house (my mom, dad, and grandma) who each do stuff independently throughout the day, he goes around to each of them around meal times begging for food until one of them gives in. Sometimes (okay, a fair amount of times), after having already been fed by one of the adults, he will go to another and act like he hasn't eaten and get a second meal. He definitely knows how to beg.
