A fox therian is a therian (shortened from the word therianthrope) that has one or more theriotypes (polytherian) of a fox and other animals, or just different types of foxes in general (pluritherian).
(Background info on a therian)
A therian is a person who emotionally, psychologically, and/or spiritually connects to one or more animals, but knows that they are a human being physically. Most therians are NOT zoophiles and a lot of therians are not furries so don’teven start complaining about that, please. Therians may also do quads (quadrobics) but they don’t have too, and may experience shifts but not always.
Luna is an Arctic fox therian! She loves to do quadrobics and lay in the snow. She only experiences shifts occasionally.
Nox is a swift fox therian, but doesn’t do quadrobics. However, she does in fact experience shifts quite often.
Briar is a red fox therian that never experienced shifts.
Sam is a fox pluritherian while Bea is a polytherian with one of her theriotypes being a fox.
An anti-therian is somebody who just like anti-furries, hates on therians. Some people think therians think they are an animal, but we don’t. That’s lycanthropy.
Example:
Nia: “My bestie just came out to me as a therian!”
Kayla: “that’s nasty, she needs to know she’s not an animal.”
