Scientists scan lion's body for clues

How many men does it take to tame a lion? Fafa, a lioness that is nearly 18-year-old, received a CT scan at the veterinary clinic in Brasilia August 7, 2012. Fafa has been living in Brasilia Zoo since her birth and had undergone surgery this year to remove both its ovaries and uterus. Fafa endured a 3-hour-long session of CT scans to her chest, skull and abdomen in order to diagnose the source of the mysterious health problems she's been experiencing.
