In order to help you we'll need to know more...
What type/size enclosure is the snake in?
Is the enclosure in a high traffic area?
How are you heating the enclosure?
What are your temps? How are you measuring temps?
Are your heat sources regulated by a THERMOSTAT???
Are there at least two proper hides offered?

What size prey are you offering? How often?
The more you tell us, the better we can help you and your snake...
