Jerry,
I am not trying to be a jerk I can be abrupt sometimes I am sorry for that. I felt since I remembered someone having that rare issue and have read about it from reliable sources it was worth mentioning. Nothing more, I didn't really want to argue with you I know we have butted heads but I hope that you feel as I do that it is not malicious or for arguments sake, but just a disagreement of minds.

OP if you choose to feed during shed feeding somewhat light would likely by pass the whole thing. In my case I don't bother offering mostly because only few of mine are likely to feed during shed anyway, it would likely just be a waste of a rat.
