I have a three year old spider ball python that has developed a pink belly from midway down to her tail. It showed up just as she was about to shed. It didn't go away when she shed and i am now very worried. I am using a UTH that i got a few years ago but it seems to be working right and isnt too hot to the touch when i feel the "hot/warm" side of the cage. when i have her out and i rub or touch the pink on her bell she doesn't react like it hurts. Please help me if you have any ideas.
