The Contaminant-Abrasive Tactile Grinder was among the most delicate tools in the factory. Commonly called the "C.A.T. Grinder" for short, it was able to process blood platelets and other small cells to ensure smooth edges at a very high speed. But it was slightly too blunt an instrument for the bile cells, so the factory bought a smaller unit. Identical to the CAT Grinder but much smaller, the crew lovingly dubbed it "The Kitten Grinder".
It runs on a fuel of human baby fat and live puppies.
