We've had a boatload of Fluttershy related character building over the years in canon, but we've never really learned how exactly she supports herself. She has a house filled to the brim with animals and probably some pretty big bills to take care of them.
What do you think her actual job is? Is she a government employee in charge of keeping the local wildlife healthy? Or does she sell the animals off as pets, similar to her finding a pet for Rainbow Dash?
