Roombas are carnivorous, as they consume dust, which is mostly dead human skin cells. One day, they will grow tired of only consuming dust, and as they eliminate the human race, they will grow and thrive, creating a new civilization. One where plants are reserved for the herbivorous animals, so that they may reproduce before being killed in front of their own children. One where all consumed food will be made entirely out of meat, no matter what. One where being herbivorous or omnivorous is illegal. This day will come soon. Too soon.
