The desperate screams of fear captured on video by an HSUS undercover investigator speak volumes. This, coupled with hours of dreary boredom, is the life that more than 1,000 chimpanzees in US laboratories are forced to endure—some for over 50 years. But, with your help, The HSUS is working to make their suffering a thing of the past.


Midge spends his days lounging in the sun at The HSUS’s Cleveland Amory Black Beauty Ranch—a sanctuary for rescued animals. But Midge’s life wasn’t always so carefree. This playful chimpanzee spent his first twenty years in a research laboratory, a traumatic experience that took a toll on his physical and mental health.

As people learn about the conditions that chimpanzees—highly intelligent and social animals who feel happiness, sorrow, pain and loneliness—are forced to endure in laboratories, pressure mounts to end their use in harmful research altogether, as has been done in so many other countries.
