Parts of China have been invaded by plagues of rats caused by heavy rainfall. The unusually high rainfall has caused around two billion rats to leave their flooded holes and move into the surrounding farmland where they have caused havoc eating crops. Villagers at first tried to poison them but eventually some people came up with a better idea. They have been catching the rats and selling them on to restaurants. The rats are the used to make rat stew which is a traditional delicacy.
