Sadly for all you cat haters out there - the part about using cats was a lie.

Christian Koch, an inventor and patent holder of the “KDV 500” that he said produces high quality fuel, said he can transform waste products such as paper, rubbish and plastic materials into fuel.
But Koch, 55, said there was no truth to stories published in Bild newspaper on Tuesday and Wednesday that suggested he used dead cats as part of the mix for his organic diesel fuel.
“I use paper, plastics, textiles and rubbish,” Koch told Reuters.
“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.”
