Koko rose to fame for her love of cats and her ability to sign language. Koko reportedly knows over 1,000 signs and understands around 2,000 words of spoken English, and is one of the very few non-humans that have kept pets.
According to The Gorilla Foundation’s website, “Koko was thrilled by the mellow sounds and a jamming session followed with Koko strumming on Flea’s bass!”
