Imagine an owner who is very generous with food at first, allowing you large meals that lead to you becoming rather chubby. Eventually, they decide its time to reduce your food intake. They take away all the clocks, and delay mealtimes by just a few minutes every day, so that you don’t notice until... "Oops! it’s too late for dinner, pet~ We can’t have you eating just before bed, after all! You’ll just have to wait until breakfast. You can do that, can’t you? Good pet~" You’re forced to go to sleep on an empty stomach, and with your stomach being used to receiving such large portions, even missing just one meal makes your belly ravenous. You lay awake as your belly growls hungrily, finally falling asleep after a while, much later than usual. The next morning... "Sorry pet, but you slept right through breakfast! Don’t worry, I’ll feed you dinner when I get home later~" They leave for work, planning to have a long night out afterwards, leaving you alone in a quiet house, with nothing to distract you from the aching hunger in your empty, growling tummy~
