Rougarou or Loup Garou (loup meaning wolf, and garou meaning a man who turns into an animal) is a shape-shifting monster that lives in the swamps of Lousiana. Rougarou is actually the Michif word for werewolf. It is like a werewolf, but it can turn into wolf form any time. This is what makes the Rougarou much more dangerous. Cajun folklore says that it stalks the swamps of Acadiana and Greater New Orleans. It is often used by parents to get their children to behave.
Catholics have their own version as well. They say that the Rougarou is a monster that will stalk and murder Catholics that do not obey the rules of Lent. Some people say that the curse (or blessing, for evil people) only lasts for 101 days. The curse is then transferred to the last person bitten.
This shape-shifter can turn into a werewolf whenever it wants. It is slightly more muscular and powerful though, because it has to cross the dense swamps. It looks a lot like a werewolf, but has some differences. Cajun lore claims that a rougarou possess the body of a man, but the head of a wolf or dog with glowing red eyes. If anyone managed to look into its red glowing eyes or gets bitten by one, they would become a rougarou themselves in a manner very akin to a typical lycanthrope.
Cow mutilations have been reported with no blood left in the body. This aspect is very similar to various chupacabra sightings. Some daring cryptozoologists have attempted to approach the Rougarou, but all attempts have failed.
