Do any individual apes stand out in your mind as particularly interesting cases?
I remember one chimpanzee who…was held in captivity in a garage by a private person. And he was in a cage that was two by two by two meters. He was fed human food—fast food and so forth. And when he came to the sanctuary, he was really, really a big person, overweight.
He wasn’t a real chimp anymore. He tried to walk on two legs—he didn’t know how to walk like a chimpanzee. He always wanted a straw to drink from bottles. That was really a terrible observation. But he received some medication temporarily, and he’s a lot better now.
