Mostly people. And an android. I guess androids are people too unless they're not. I was talking to someone who said she was a former alien-hunter so who knows, we probably have aliens. Aaaand I may or may not have seen a talking cat walking around. Which I guess I shouldn't find that weird considering I used to know a super-intelligent horse, but he had people to do his talking for him.
