I agree with Jodan. Your snake sounds hungry. But that's based on the limited info at hand.
-What type/size enclosure is the snake in?
-Was he moved recently? To another enclosure or room?
-What are your temps? Humidity?
- How are you heating the enclosure?
- ARE YOUR HEAT SOURCES REGULATED BY A THERMOSTAT???
-How are you measuring temps? And where?
The more you tell us the better we can help.
