I agree, I don't handle my snakes when they aren't eating, other than to clean the tub and take weights. Wether we like it or not, snakes can get stressed from handling.

Do you happen to have a picture of your setup? Also, are you using a thermostat with your heat sources? What kind of thermometers are you using?

Sorry for being so nit picky, but these details could mean the difference between your snake eating and not.

Is your snake fairly active? What kind of hides do you have? Is the snake in the hides more often than not?
