Today I was just searching the web and i just had a thought. How am I supposed to measure the temperature in the cage? On every article I read it just says that you have to maintain the temp. at 72 degrees to 80.It never mentions how to moniter it. Do you get one of those sticker thermometers in the cage or a lizard thermometer or a suction cup thermometer???? So what do you use and what do you think'll be the best??? THANKS!!!!!
