Con Slobodchikoff says that humans don't have the monopoly on thought or structured language.
An animal behaviourist and Professor Emeritus at Northern Arizona University, Con has shown that some animals do have their own vocabulary, the ability to describe what they see - and what they can't.
His next project is a type of animal translator which Con hopes will revolutionise the way we see, interact and communicate with, the animals that share our world.
He joins Anna from Arizona to explain.
