I got my first ball python about a month ago. He's a male pastel coral glow yellow belly that was born 10/12/15 and last shed around Christmas before I got him, so I haven't experienced a shed yet. I thought I could detect a pink belly well over a week ago and then several days ago I thought I noticed a slight blue/gray hue to his eyes. But his eyes still have not turned that unmistakable cloudy blue. Now I'm wondering if he's in shed at all. Maybe his eyes were always just a little blue but I never noticed it before now?
Anyway, my question is will a snake's eyes always turn that opaque cloudy blue before shed or could it be a very slight blue/gray with no distinct cloudiness? Yes, I know, a snake will shed when it's ready, I'm just trying to detect if it is indeed in shed, for curiosity's sake.
Here's a picture of him from a few weeks ago when he was most definitely not in shed.
Thanks!
