During the late 1940s and early 1950s, Keith and Cathy Hayes
reared a baby chimpanzee named Viki as if she were a human
child. In _The Chimpanzees of Gombe: Patterns of Behavior_,
Jane Goodall writes:
During the long battle to toilet train Viki she was
rewarded for successful performance with a candy.
The late Leonard Carmichael told me of an incident
that took place when he was visiting the Hayses.
Viki, on her way to the potty, paused to jump up on-
to the sideboard, where she took her reward from a
jar. Perhaps as a result of this delay, things did
not go as she (presumably) had anticipated. To her
visitor's amazement a subdued and damp-bottomed Viki
climbed up and returned the candy to its jar. He
was the only person in the room with her.
Cathy Hayes' own account of her experiences rearing Viki is
entitled _The Ape In Our House_. It's a superb read.
