IMPORTANT NOTE this mange was originally created back in the 1990's, and back then what got published for the American market had the pages "flipped" so that they read like a typical American comic, from the upper left corner down to the lower right corner ............. BACKWARDS from the way manga normally reads .......... so if you try to read this like a normal manga it will be very confusing the original title of this when it came out in America was "Apocalypse Meow" and was 3 vols this version is much later (but still has the pages flipped) and it contains all of the original story, plus extras this story is about the Vietnam War that America was involved in, but it uses various anthropomorphic animals for the different nationalities that were involved in that war https://www.mangaupdates.com/series/yj3d984/cat-shit-one
