I gave it a nice long soak in warm water, seeing as how its eyes have turned blue, hopefully the shed goes smoothly and isn't too much trouble. After drying the snake, I put some diluted betadine on its problem areas, along the ventral scales. It looks like there MAY be some discoloration around the underside of its jaw and behind the head, I carefully applied some there, though I didn't want to get too close to the mouth. I'll keep updating on the progress though! I want to keep this well documented, if I find a vet then I can take everything in to them, or if I want to file a formal complaint against petco (not that I believe that it'll make a difference, but ya never know) then I have proof, and all the pics on my phone have timestamps so they can't accuse me of being at fault.
