I've thought about things like this. What if humans could be kept by aliens as pets? What would that be like? Can any extremely bored writer reading this come up with something?
Funny, I actually have a running story in my head like this. People kept in little cages like hamsters, aliens choosing breeding pairs, or training them to fight each other. Some aliens would be debating the ethics of it all while others go, “Humans are much stupider than we are, so it’s okay to treat them like this.”
