Ball hasen't moved in 3 days..worried

[Bogertophis]

Seems like he really is shedding soon. My boyfriend said he has dulled quite a bit and has clowdy eyes now.
And he's still moving in the hide.
But it's still scary not seeing him out for almost a week.
I mean I know snakes don't drink much but how long can they really go without water.

Stop worrying- he's in shed. As for how long they can "really go without water"- how often does it rain? Some snakes live where there are virtually no bodies of water, only rain now & then.
That's why they don't waste water when they excrete waste products.
