O.k while quizzes are cute familiars are an actual thing and I just want to quickly throw it out there that this is not how you discover who your familiar is.
A familiar is an animal that shares a deep spiritual connection with a practitioner and somehow assists in their practice. You'll often see black cats in drawings of witches, those cats are based on the concept of familiars. Of course black cats aren't the only possible form your familiar can take, they can come as a rat, owl, dog, horse, or anything living in the animal kingdom.
The way to find a familiar may differ. Sometimes you can attempt to use divination to bring you closer to them. You can also try meditating in an open area and wait for them. Of course you can also just choose your familiar and build that spiritual bond over time. It is never guaranteed that you finally acquire your familiar.
Something to keep in mind is that familiars are not pets nor are they spirit guides. They're an animal that naturally likes you and decides to help you with your work. Sometimes familiars can be wild and sometimes domestic, it really depends on when or where you find/meet them.
