Should food not be offered when in blue?

[Bogertophis]

... I've had bad sheds when I've missed them being in blue or about to shed...

Same here, over the years, so if I notice first, I just don't offer a meal.

...he took a a warmed up rat one day ( whilst in shed ) but didn’t bother to eat it .... unbeknown to me of course !!! ...The smell after a few days was absolutely disgusting !!!! ...

And that right there is "the" cure!
