So I am currently in school for Elementary Education and tomorrow I am going to my third grade classroom to observe like I do every week. Tomorrow is my day to introduce myself to the students so they can really start to know me. I asked the teacher of the classroom if I could bring in one of my critters. I decided I'd like to bring Squirt my corn snake in to show to the students. After all, tomorrow is Halloween. My question is this. I have a critter container to put him in but will he be ok in it for 3 hours without a heat source? I plan on keeping him in the critter cage inside a very nice travel bag that I have. The weather is getting cooler, so I just wanted to make sure he'd be ok for a few hours away from his heat source.
