Awwww, the lovely Jarv...
Bella (aka Queen B - there really should be a smiley with a crown on this site) loves raw eggs but does not deign to eat the shellsas she is a lady of discerning tastes.
Zorro (aka canine dustbin) eats the egg plus shell and then eats Bella's shell as well. In fact if I'm making scrambled egg I give him the shells as a yummy (not sure why, I can't think of anything more revolting than chewing up an eggshell myself!
) treat.
