A Centaur has a man-stomach and a horse-stomach. And of course both want breakfast. So first of all he has porridge and pavenders and kidneys and bacon and omlette and cold ham and toast and marmalade and coffee and beer. And after that he tends to the horse part of himself by grazing for an hour or so and finishing up with a hot mash, some oats, and a bag of sugar. That's why it's such a serious thing to ask a Centaur to stay for the weeekend. A very serious thing indeed.
