This is a nice puzzle for children that I picked from the book “Moscow Puzzles” (Puzzle #88).
See the figure below: Cat has decided to take a nap. He dreams he is encircled by 13 mice: 12 gray and 1 white. The cat hears his owner saying “Cat, you are to eat each 13th mouse, keeping the same direction. The last mouse you eat must be a white one.” which mouse should the cat start from?

Happy mice eating!
