King Uros II of Serbia believed that he was cursed by the Devil with lycanthropy, and thought that he became an animal by the light of the full moon. But unlike the more common ideas of werewolves, he believed that he was a weregoat. He had periods where he would think that he was a goat. During these times, he refused to wear clothing, and would only bleat. His courtiers eventually learned that the easiest way to deal with him at these times was to lock him in a room with a bucket of kitchen scraps and a bowl of water. After several days he would recover. Unfortunately, this indirectly led to his death in 1161 when he ate a bunch of eggshells while thinking he was a goat. He died from salmonella.

Since 1900, the incidence of fangs among herbivorous mammals has increased 700%. There have been well-documented cases of fangs in cows, goats, yaks, sheep, deer and camels. It has been suggested that environmental pressures have been selecting for herbivores who supplement their diet with small animals. One scientist interviewed on the matter said that the "most frightening thing he had ever seen" was a small island in the Caspian Sea that seems to be the base for a population of carnivorous, and in some cases, cannibalistic goats.
