The story of the Ninja Cats is one of those very funny classic 2chan stories. A dude who believes he got attacked by ninja cats, bipedal cats wielding kunais and blades and the likes, that updates the story as he goes. I believe there was even an embedded picture of some blurry thing outside of the dude's supposed apartment believed to be one of the ninja cats. The 2chan story just ended the way this chapter does. The poster says he's fine, he's not satisfied and will look into things more, etc. A good 2chan story.
