She is very stubborn, which is why it is hard for scientists to demonstrate her intelligence. Koko did demonstrate her intelligence though, without even realizing it. She had requested that, "Visit Love Tiger Cat". A caregiver brought Koko kittens, Koko picked a gray tabby that had been born with no tail and named it All Ball.
