Do any snakes eat their own skin after shedding/moulting?

A post was split to a new topic: Reply to Chronos with too much Info

I imagine it’s for the same reason most human mothers don’t eat the birth placenta. Snakes have their own taboos.

I wonder if the skin, A.got balled up B, became rat scented ? I’ve been collecting, breeding, etc. all manner of herps since 1968, never saw a skin dinner. Btw I trained my F3 pink and white licorice stick black rat to eat chicken dog food out of the can. I’ll try for a pic.
