There's a gallery of variant versions of Cinderella from different countries, even China. In many of them she has an enchanted cow.

"If once a man indulges himself in murder, very soon he comes to think little of robbing; and from robbing he comes next to drinking and Sabbath-breaking, and from that to incivility and procrastination. Once begun upon this downward path, you never know where you are to stop. Many a man has dated his ruin from some murder or other that perhaps he thought little of at the time." -- Thomas De Quincey
