I may be misunderstanding what you've written

 I may be misunderstanding what you've written. But it sounds like you have picked up on changes that occur in Caesar's body posture and language just before he attacks. If that’s so, you are halfway to solving the problem. It sounds like your cat is becoming overstimulated from being caressed and petted. That does happen with some cats. Sometimes overstimulation is simply a matter of time. Two minutes of cuddling may be fine and Caesar is his usual sweet self. But 2 minutes and 15 seconds crosses the line. Every single time. And Caesar bites. Stopping the cuddling at 2 minutes = no more bites.
