I completely agree about UTH needing a thermostat. I can't believe that they don't have one built in. If it's marketed for reptiles, and every reptile has different needs, why is it not built in? If it's not included for personalization why do the pet stores, and their care sheets not carry/note it? I live in the Kansas City area and called 12 pet stores. 2 had thermostats and neither of them were exact temps (low, med, high). Our family is new to snakes and I'm livid as to the horrible information pet stores give out.
