A good use for cats?

[javasaurus]

It was rumored that a German engineer was turning dead cats into diesel fuel. Actually, he has found (and patented) a way to generate "bio-diesel" which he has used to power his car for over 100,000 miles, but he didn't use cats. (So there is still no good use for them, but they're cute anyway!)
