After spending a week with a dog in the house, my youngest learned many new skills. At the end of a meal, she now joins her sisters in a chorus of "Done". She also politely tosses her surplus off the edge of her tray. Poor Sammy is probably going to have a tummy ache after all the childrens bits they fed him "accidentally" and his job cleaning up thier usual surplus left in the high chairs.
The real problem comes in differentiation though. If Nanis pet loves leftovers then our pet must as well. Our cat Bombay views small chunks of chicken hurled at her not as a blessing, but as lava fire balls from hell.
