Whatever you do, make sure that you don't leave foods at Stevie's fingertips or should I say paws? grapes can cause kidney failure, onions can cause anaemia.
And is it realistic to expect that one day Stevie (labxGR) will learn NOT to eat whatever is on the floor right in front of her???? We're trying, really!
Short of a miracle, NO, you could succeed in training Stevie to leave the food well alone whilst you are watching but you can bet your life that as soon as your back is turned, Stevie will show his unique talent at dish washing, lol.
