A researcher on animal behaviour has told FRANCE 24 how he and his colleagues have been mind blown by the story of the cow that uses a broom to scratch its back. Veronika the cow has been shown to pick up and use a broom. She even chooses the soft end or the handle, depending on whether she wants to scratch her thicker or more sensitive skin areas. The researchers say her story significantly changes the way we should be thinking about cattle, and potentially about other animals as well. Antonio Osuna Mascaro, from the University of Veterinary Medicine in Vienna, spoke to us in Perspective.
