I've noticed a weird spot last night on my ball pythons belly. It looked like some kind of a burn or something, i'm not entirely sure what it is because I've never seen a snake burnt before.. I used to keep my heating pad IN the plastic tub because it wouldn't stick from underneath but after seeing that belly, I took it off right away and put it from the outside. Here's a picture of it.. I've also noticed that the belly have turned it's colour to pinkish - beige, i'm not sure if it's about to shed because it shed around 2 months ago.. does this look like a burn or possibly a skin rot? And by the way it's a one year old female BP.
