To all the lurkers out there and new people looking for information on a set up for your new snake that happened to come across this thread, and watched in awe the picture of this poor snake... let this be a lesson. DO NOT avoid spending the extra $30 - $80 on a thermostat because this will definitely happen, sooner or later your baby snake will get burned and the Vet bill will be 10 times the price of a thermostat.
Everyone here says it to new people "get that UTH on a thermostat", but some just don't believe it. Well, here is proof of that. Be smart, be responsible and be compassionate to the helpless animal in your care.
