Glory
You will be rescuing helpless, tiny, sweet little muffin-faced doggies and kitties; you'll also be rescuing slightly-less-helpless, slightly-less-tiny, kind-of-looks-like-it-wants-to-eat-me wildlife. Whether it's a puppy or an owl, a doe or a coyote, a lost kitten or an enraged bear—you help them all.
You're a hero of the best and most pure sort: the kind whose reward lies in knowing that you're out there doing good every day. And, yeah, the people you bust for abusing animals will hate you and call you names. But do you think Superman stays up all night worrying about what Lex Luthor thinks of him?
