A traditional Welsh belief is that a lone fox spotted indicates that good luck is sure to follow in a short amount of time, yet if the fox then chooses to cross your path the reverse is true.
A fox bite was once thought to be fatal in rural folklore as the animal, also thought to be vermin, was associated with the Devil and witchcraft. Perhaps this is one reason why the hunting of foxes began, to chase the Devil across open land, and to catch and kill him to rid him from troubling the community. According to some beliefs ripping apart a witch was a successful way to kill a witch and protect the land by providing a sign to any others interested in troubling the area.
The appearance of sun and rain on the same day was believed to be a sign that a fox was enjoying himself, and getting married!
