Aliens took over the planet long ago and now see humans as pets. The aliens have made shots and other medical practices to bring humans back to their primal and raw instincts. Some humans are considered more prettier “breeds” then others and are in higher demand. Most humans live as pets for aliens but some get special jobs that help aliens and others are just breeders. The breeder humans are carefully taken care of in a huge spaceship that has rooms that look exactly like their habitats.
