Petra, 2004


Petra was not quite 2 years old when she had her first surgical procedure-an amputation due to a finger caught in a cage. In 9 nine years Ch-560 was used in only 2 studies. The first gave her a fever for a week that was left untreated. Shortly thereafter she was found to be chewing the paint off the wall, suffering from diarrhea and lack of appetite. Despite her involvement in only 2 studies, she endured 185 knockdowns and 7 punch liver biopsies. Maybe this is why she spent her days circling her cage like a hamster in an exercise wheel, aggressively plucking most of her chest and arms bare of hair and rocking nervously in a constant state of stress and agitation.
