Forget Ratatouille, this is the real thing: an estimated 2 billion field mice are on the run in the areas surrounding Dongting Lake (洞庭湖) in Hunan province. The mass migration was caused by the flooding of the Yangtze River in late June. Since then, as you can see from the news report in the video, people have been busy trying to control the mice by both erecting walls and barriers and also by trying to kill them. However, according to reports they’ve only managed to exterminate 2.25 million of them (or 90 tons of mice), a mere 1/1000 of the total.
You can see lots of news reports and follow-ups (in Chinese) here.
The great irony, of course, is that while there are 2 billion mice on the loose, people are still capturing and eating cats. Check out the video, people are using shovels to kill mice—but why not let some of those captured cats help out? Cats can see in the dark, whereas humans need electricity to power lights so that they can see where they are aiming their shovels, and also because being surrounded by millions of mice in the dark would probably scare most of us shitless.
