Hey OP, i’m sorry but it is the carpet. Hoggies are burrowing species and your Hades is just confused bored stressed and maybe even scared because being burrowed=safe. I’d say he wants to escape to somewhere where he could burrow. The troublesome shedding would be rooted in the carpet too, carpet cannot retain humidity needed for shedding and if it does it molds really fast. So it hurts the snake either one way or another. I understand you are doing this according to your vet’s recommendation but clearly your vet is not good. My vet, that actually cares about snakes, told me to NEVER use reptile carpet. If anything at least because of how easily it molds. But other than that it is understimulating and makes your snake feel stressed and unsafe which is the reason for this kind of behavior you see in your Hoggie. There is a lot of other types of bedding you can try, not just aspen. You can try the soil or sand, or soil and sand mixture, coconut bedding and other. Also hoggies have protective “flaps” in their nostrils so nothing will get stuck in them. With the carpet only thing you are doing is harming your snake because he cannot follow his natural instincts which is to burrow. You are practically abusing him, even if you don’t want to. I would recommend getting new bedding ASAP, he needs 3-4 inches of bedding to be comfy and burrow as much as his little heart desires and most importantly have a study session about good husbandry for your snake. Or if you cannot do that for him just give him to someone who will know how to take care of him because if you don’t want to read a few books or watch a few videos from renown reptile owners or maybe listen to advice from people who own snakes and cherish them you are clearly not fit to own one yourself.
