The Werefoxes or Alopecanthropes are individuals who can shape-shift into a fox or fox-like being. An alopecanthrope can transform between human form and that of a fox or a fox-like hybrid during the full moon. The female werefox is called Werevixen or Vixen.
A werefox that has just turned.
Werefoxes will not harm you if you don't mess with their babies. Werefoxes are (common) skinwalkers of Eastern folklore, but it's not (uncommon) in the myths of other lands. It is so stereotypically the prime shapeshifter of the East that the Japanese word for fox, "kitsune", has greater meaning now & is applied worldwide. Despite all kitsunes are alopecanthropes, kitsunes are yokai demons based on wild foxes that worship the goddess Inari.
Outside of myth & legend, these were-vixens are pretty common in the spiritual therianthropy subculture. I'd estimate that they are the most common species other than werewolves. Therefore, werefoxes & foxes in general are a pretty strong interest in the spiritual therianthropy subculture. It's interesting to note that foxes are probably the #1 animal in (furry) subculture, so this is one major area of intersection for the 2 communities.
The most easily noticable thing about werefox legends is that the werefox is an overwhelmingly female creature, males are rare. This fact has really influenced the view of werefoxes that has built up in the spiritual therianthropy subculture (the essences of foxes is viewed much the way it is depicted in furry culture: as a feminine, flirty vixen), however don't despair if you are a male werefox. Despite the gender skew in legend, there are quite a few male werefoxes running around the spiritual therianthropy subculture.
