It’s one of those stories that’s heartbreaking enough to bring a tear to your eye, and it all centers around a chimpanzee named Foxie. Born in 1976, Foxie has spent much of her life in a laboratory, subjected to research on hepatitis to vaccines. Eventually, she gave birth four separate times to four healthy chimps, each of them taken from her and relocated. Foxie’s temperament changed over the years as a result of having her babies taken, and when she finally retired in 2008 to a chimpanzee sanctuary, her caregivers from the lab warned that she couldn’t be trusted. However, the kind folks in the lab had some ideas for how to make Foxie happy, and what they did will warm your heart despite this poor animal’s tragic circumstances.
