#   <herd name="Cathy">

# 	    <animal>
# 	        <name>Molly II</name>

# 			<gender spay-neuter="yes">F</gender>
# 			<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.
