You have probably heard about Koko the gorilla. She is known for understanding and communicating through the sign language. Unfortunately, the friendly animal cannot have “kids”, so her carers came up with a funky idea – how about adopting one? She was shown a few pets and she chose two kittens.
Before this choice, Koko signed that she wanted a cat, but she received a toy one. She was unsatisfied with it though. Now, after 20 years, she is finally allowed to have a few pet and take care of lively animals. Koko is 44 years old and understands over 2,000 signs and words.
