The cat is out of the bag!  There are a couple of theories as to the origin of this idiom.  One is from the high seas where disobedient sailors were beaten with a whip called a cat o-nine tail.  A leather strap with nine knots tied in it.  It was kept in a bag to keep it from drying out in the sea air.  If the cat came out of the bag, someone was in trouble.  The other theory is from someone buying a pig in a bag, but the seller would switch the pig for a cat and the unsuspecting purchaser wouldn’t know until he got home and let the cat out of the bag.  Both of these are a bit far fetched, especially the second one.  And neither one explains how letting the cat out of the bag is related to revealing a secret, which is what the idiom has come to mean.
