Cultural note from the author

The book is based on real-life, about my father and the two rescued cats.  The story was written by my mother, and all the photographs were also taken by her. You can see from the photos, how much these two cats are loved and spoiled by them.  In fact, the cats are ruling their house, aren’t they!  Among the many mischiefs they get up to, the best one is destroying the shoji paper completely. Only cats in Japan can enjoy doing such a thing!
