#             <info>Molly came from a place where an old, ill man had too many animals.
#                       The animals were seldom fed and rats would eat the newborn piglets.
#                       When Molly was found at one week old, she was the only piglet of
#                       her siblings who did not get stepped on by a cow. She is a sweet,
#                       friendly pig who likes to hang out on Cathy's porch on the lounge
#                       pad.
