Chris, I am sure you're not the only one. I think I accidently killed Imhotep about 10 years ago. He was a hatchling corn snake, and I didn't know that UTHs got too hot. He was given to me, with vivarium, UTH, etc, by someone who owned other snakes so I ~assumed~ the instructions that person gave me were correct. Mind you, Imhotep lived for several months & gobbled down pinkies, seemed active, was growing, shedding, pooping. Fed him. Next day he was fine, in his hide digesting, temp was probably OK in that hide (I didn't know about putting a thermometer on the glass but he was on the cool side & it was summer & apartment temps were about 75F & he was not in sunlight so unlikely to be higher), next day, gone, curled up in his hide.
