You will need money for tailored clothes, alterations to your vehicle (because humans designed the seats for tailless bottoms), a good veterinarian (this is not a joke, I'm serious, GOOD vets cost ALOT), a lawyer to protect you from humans who hate the sight of you, new ID cards (driver's license, health cards, that sort of thing), change of name documentation, and other mundane but necessary things like dog toothpaste (because human toothpaste has detergents that cause animals to froth at the mouth), pin brushes, pet nail clippers, medieval swords, that kind of thing."
