While my little Shiro has a gigantic heart, she also has a stomache to match its size. Sadly, she has been on a diet for the majority of her life, but the poor little critter's metabolism just can't burn away the chubbiness. Needless to say, the prime point of annoyance employed by the munchkin is based around her desire for food. Her perpetual state of hunger, coupled with her insatiable desire to vocalize every trivial, little desire is a recipe for my insanity. Fortunately, I've found a way to counter the effects of madness by employing concept number two: Extreme Disappointment.
Simply wait until one of the victim's meal times, preferably when they are actually indicating a desire for food. Take out the source of sustenance (whether it be a bag, pouch or tupperware container), open it, feign excitement so as to increase the animal's own zeal, and give them one piece of food. Just one. The expression on Vesuvius's face is priceless when I employ this tactic, a mix of disbelief, desperation and utter contempt all mixed into one. Of course, I only let this go on for about a minute, but that's all that is necessary. This speaks a message to your cat: "I'm the food master, and if you don't like it, go eat a rodent." (If only they'd care...sigh)
