I offer all my snakes food while in shed, some eat, some dont, and sometimes they do what they feel like. If you want to offer food, offer, if you don't then dont.
This is true, sheds can cause whistling, what you want to look for is any fluid or bubbling in the mouth, that is a sure sign of an RI and a vet visit and culture of fluid would be needed. Bumping up temps to the mid 90's wouldnt hurt just in case it is the begining of an RI.
