You would need to measure the kicks quite carefully then. I mean damn, if I don't get a blood diamond every time then I'll be upset.

Also, what kind of temperament does this cat have? Is it a cat that doesn't mind being kicked pretty hard or does it cower and squeal in pain? If it's the latter then the guilt factor could play a big part.

Also, can we provide the cat with padding to minimise damage yet still have maximum productivity?
