I read somewhere ... can't remember where (hehe) .... that when a cat bites, he expects you to pull back on your hand ... just as prey would. That is why cat's teeth curve inward ... so that the pulling-back motion actually sinks his teeth in DEEPER! You are actually supposed to shove your fist, hand, etc. in further into his mouth to take him by surprise, and thus release his grip on you.

NOW.... I can say this... I "ain't never tried it myself... GOOD LUCK"
