Cheeta the Chimp's "autobiography" nominated for Booker Prize

Chimp's memoir among contenders for Booker Prize:

"The purported autobiography of a movie-star chimpanzee is among the contenders for Britain's most prestigious literary award."

Wait. It's an autobiography, and the prize is only available to people from Britain, Ireland or the commonwealth. That means Cheeta was British? A win here could get him knighted as Sir Cheetah.
