Once upon a time, there was an evil robotic feline-like scientist. This feline wanted to take over the world by making humans stupid and eventually turning them into cute yet dangerous felines.
So, one day, he succeded in making a wonderful machine to make a feline. He breathed into the felines’ nose and annouced “Youz be kalled kitty kat, for youz be perfekt. Youz take over da world by kutiness.” He released the feline onto the world, and that’s how this all started.
