Will Koko make a good mom? We think so. Koko is the most loving surrogate mom to her baby dolls (human and other great ape) and kittens, and is very patient with those around her – for example, when they don”t know as much sign language as she does, and she has to repeat herself in many different ways. Will she be a mom soon? That will probably be Koko”s birthday wish this July 4th!
