I’m just worried, there’s been an outbreak of cryptosporidium serpentis in my area around reptile shows so it is the first thing that I thought of. If you haven’t had any new reptiles or haven’t had the snake exposed to any reptiles that might have it it’s probably not. But I would have the stool checked. There are a number of other parasites that it could be that can be taken care of with drugs. It could also be husbandry issues. I would clean everything really well make sure everything is correct like temp and get the stool checked. I hope everything turns out for the best good luck.
