The German newspaper Bild yesterday reported that an inventor, Christian Koch, had developed a method to make bio-fuel out of dead cats. 20 cats would be enough to fill one gas tank. The story quickly spread to other media outlets, and animal-rights activists expressed concern: "The president of the German Society for the Protection of Animals, Wolfgang Apel, said using dead cats for fuel was illegal... 'We're going to keep an eye on this case,' Apel said." But it now turns out that Bild's story wasn't totally accurate. What they meant was that, in theory, one could use dead cats (or any other organic material) to produce the fuel. But the inventor insists he never mentioned the use of cats: "It’s an alternative fuel that is friendly for the environment. But it’s complete nonsense to suggest dead cats. I’ve never used cats and would never think of that. At most the odd toad may have jumped in." It seems that Bild got the idea for the use of cats from the name of Koch's company, Alphakat GmbH.
