There is an infestation of rodents in the neighborhood. The karate master wants to make sure that no rodents defile his dojo, and so he brings a cat into the dojo to keep guard. The cat is able to keep most of the mice out of the place -- but there is one particular mouse who is different from all the rest.Just a short, short story to entertain you -- and to remind you that martial arts are accessible to everybody. There is a short glossary of Japanese terms used in the story, at the end.
