Neko No Mure – The Art of Herding Cats. Inspired by Japanese style ‘paper and pencil’ logic puzzles, Neko No Mure is an original puzzle and the first to be created by Windwhistle Designs. To complete each puzzle you must ‘herd’ fifteen cats into five distinct enclosures. Each enclosure must contain at least one cat and no enclosures can contain the same number of cats. Each book contains 56 puzzles, complete with answers.
