Yahoo News is reporting that the rat population in Tehran is growing, and not just numerically. Local rat catchers are bringing in rats up to 11 pounds in weight and impressively long. The one in the picture at the link is either covered in debris or is growing scales or something.
With shortages of everything in Iran, this could prove to be a new and important source of meat for the locals. How do you say "beef" in Farsi?
This would help prevent things like the discovery in Iceland that beef pies not only contained no beef, they contained no meat of any sort.
