Jane Goodall discovered half a century ago that chimps use tools. This week, scientists discovered a cow can do the same. This cow even learns to use the hard bristles on her tougher back skin and the smooth end for sensitive parts, like her udders. Watch this!

![Veronika, a Swiss Brown cow living on a farm in the Austrian Alps, has achieved something no cow has ever been documented doing before: she deliberately picked up a broom to scratch herself, demonstrating true tool use. For years, her owner had observed Veronika grabbing sticks and brushes with her mouth to relieve itches—an intriguing but seemingly quirky habit. When scientists decided to investigate, they put her behavior to the test. In controlled experiments, researchers placed a broom on the ground in front of her, sometimes with the handle facing her and sometimes with the bristles toward her. Veronika consistently chose the right approach: · To scratch her tough, thick-skinned back, she grasped the handle and used the bristly end. · To reach more sensitive spots—like her udder or navel—she flipped the broom and used the thinner handle end. She adjusted her grip, reoriented the tool, and even seemed to anticipate which body part she wanted to scratch before picking it up. This was no random or accidental action; it was purposeful, flexible, and goal-directed—clear evidence of tool use. Until now, tool use in animals was considered a hallmark of high intelligence and had only been reliably documented in a select group of species: chimpanzees, crows, elephants, dolphins, and a handful of others. Veronika has become the first cow ever recorded using a tool in this sophisticated way. Researchers suggest that her unique environment—as a cherished family pet with plenty of freedom to explore and interact with objects—likely encouraged this behavior. But her accomplishment hints at something more profound: cows may possess a greater cognitive capacity than we have long assumed, one that has simply gone unnoticed until now. [Osuna-Mascaró, A.
