Sand boa help please!!

[Bogertophis]

For young snakes like yours, this sounds pretty normal to me. I've kept many kinds, not KSB specifically, but here's the thing: you said she's a good
feeder, and young & small snakes like sand boas can only eat small prey that's digested quickly, so they do a LOT of eating, which results in a lot of shedding, since
that's how they grow. It's normal for a snake to refuse food when they are in a shed cycle (often they start refusing before it's even obvious to us...somehow they
know) and what you're seeing right now (wrinkly) is normal, though you might want to offer a "humid hide" right now, while she's shedding, to help things along:
the fact that some old skin has already come off but not all at once (especially since her eyes are still cloudy) it suggests she is overly dry & may need a little help.

Does she have a water bowl? shedding requires extra moisture from the snake's body (they actually secrete some moisture between the old & new skin to help the
old skin come off) and guess what? digestion also requires hydration from the snake's body, so the fact that she ate a bigger meal recently is why she is now having
a bit of trouble with shedding. Some snakes will still accept food when going into a shed, but personally, if I know about it, they don't get fed, as I don't like to deal
with stuck sheds. So like I said, fix up a "humid hide" A.S.A.P.- even if it's just damp paper towels in a hide, rather than moist moss. Make sure after she sheds that
her eye caps shed OK, also check her tail tip...a few missed sheds left on a tail tip can result in the death of the tissue underneath (since the blood circulation is so
easily cut off by the tight skin) & they can lose part of their tail that way.
