Have you heard of Veronika? The 13‑year‑old pet Swiss brown living in Austria has gone viral for being the first cow documented using tools intelligently and flexibly—a revelation that has stunned the scientific and global community. We’re honored to welcome Antonio J. Osuna-Mascaró from the University of Veterinary Medicine Vienna’s comparative cognition team, who led the study on Veronika. Antonio explains why his area of research is extremely picky about what constitutes tool use—it requires more than just interacting with an object. It’s about an animal handling an object to extend their own body’s capabilities to make the impossible possible. Tooling is a phenomenon that is extremely rare in nature, yet touches a wildly diverse list of species, from Goffin’s cockatoos to dolphins, elephants, chimpanzees, crows, and even digger wasps. Although Veronika started with sticks and rakes, the study team provided Veronika with a broom, observing that she was not only able to use it to extend her ability to scratch parts of her body she otherwise couldn’t reach, but also that she had awareness and sensitivity to the two parts of the broom: the stick end and the brush end. Veronika preferred the brush end for most scratches, but switched to the gentle handle end to deliberately and precisely reach sensitive areas like the base of her tail—a flexible tooling behavior that astounded Antonio and his team.

Matt and Antonio explore what about Veronika’s life in Austria might set her apart from other cows, what the team is studying next, and why their initial findings challenge long‑held assumptions about cow cognition. The two explore what they hope is the impact of these findings; that all scientists humbly reconsider the creatures we thought we already understood.
