It turns out that rehab is not for celebrities anymore: ‘Monkey rehab’ is the playful way that many describe the work of the ‘Great Ape Project.’

Located in Brazil, the Great Ape Project rescues non-human great apes like chimpanzees, gorillas, orangotans, and bonobos from dangerous and abusive zoos, research labs, homes, and circuses.

The Great Ape Project offers animals a sanctuary and a second chance. View the pictures above to see some of the clientele, and check out another video on the Great Ape Project here.
