not being mean or any thing but y do I need a thermostat for my snake for any under tank heater? i thought snakes have a built in thermostat? as long as you heat the item be for you put it in... that way they don't lay on it and the body temp raises with it and they get burnt. Oh and I love my snake but shes no prize snake so little marks are not a big thing. any was, I just don't have a lot of money, the eggs are do 2 weeks after my baby is due. and I AM NOT going into WHY I WAS TRYING TO HAVE EGGS AT THE SAME TIME IF I DID NOT HAVE THE MONEY FOR THEM. so lets not go there. as for the holes in foam its my only way to keep the temp down or it would be 110 degree in there. I will be waking up every 2 hours to check the temp.
