Former Price Is Right television host Bob Barker donated $500,000 to rescue and build a new habitat for five HIV- and hepatitis-infected chimpanzees, according to a Chimp Haven statement. The chimps were subjected to biomedical research, and they range in age from 37 to 41 years old. Last week, they moved into their new home in Keithville, Louisiana. Barker stepped in to help the animals after he heard they were stranded at a bankrupt Texas facility and had been denied housing because of their illnesses.
