Koko's Kitten -- a classic kids' book

[Heartbreaking video link] I really like Burgin Streetman's blog called Vintage Kids' Books My Kid Loves. Today, Burgin wrote about Koko's Kitten.
Any child of the 70s and 80s knows the story of Koko, the orphaned gorilla child who was taught to speak sign language and communicate with humans... This is the sweet, but heartbreaking tale of Koko and her pet kitten, All Ball (Koko named it herself). The joy she feels upon receiving it as a gift and the grief when the animal is inadvertently run over by a car. If nothing else, this story illustrates how closely linked we as human beings are to these incredible creatures.
