Iβm less interested in knowing who let the cat *out* of the bag than knowing what crazy person thought it was a good idea to put a cat *in* a bag in the first place.
You made me curious:)
Merchants would sell customers live π and, after putting a pig in a sack for easier transport, would sometimes swap the π·for a π when the customer looked away. The buyer wouldn't discover they'd been cheated until they gotπ and literally let the cat out..
