A Cow Just Used Tools in a Way Scientists Have Never Seen Before

In 1982, cartoonist Gary Larson published a Far Side comic called “Cow Tools.” It showed a cow standing proudly beside a collection of bizarre, useless objects. The joke was simple: cows are not intelligent enough to use tools. More than four decades later, a real cow named Veronika is making that punchline complicated.

A study published in the journal Current Biology in early 2026 describes the first documented case of flexible, multi-purpose tool use in cattle. Veronika, a Swiss Brown cow living in the Austrian village of Notsch im Gailtal, has been using a deck brush to scratch herself — and she does it with a level of deliberateness and adaptability that researchers say was previously documented outside of humans only in chimpanzees.

What Veronika Actually Does

The research was conducted by Antonio Osuna-Mascaro and Alice Auersperg of the University of Veterinary Medicine in Vienna, who traveled to meet Veronika after her owner, organic farmer Witgar Wiegele, shared video footage of her behavior. Wiegele had noticed Veronika picking up sticks to scratch herself roughly a decade ago. When cognitive biologist Auersperg saw the footage, she said it was immediately clear this was not accidental.

In controlled trials, the researchers placed a deck brush on the ground in front of Veronika in a random orientation. They recorded which end she selected and which part of her body she targeted. The results, replicated across dozens of sessions, showed consistent and functionally appropriate choices. For broad, firm areas like her back, she chose the bristled end. For softer, more sensitive regions of her lower body — the udder, belly flaps, and anal region — she switched to the smooth handle end. She also adjusted her movement technique, using stronger scrubbing motions on tougher skin and gentle pushes on delicate areas.

Why This Is Scientifically Significant

Tool use is defined as the manipulation of an external object to achieve a goal through physical interaction. Veronika’s behavior meets that definition — and exceeds it. What makes her case particularly notable is the multi-purpose dimension. She is not simply using a tool; she is using different features of the same tool for different outcomes, adjusting her approach based on context. According to the published study, this type of flexible, egocentric tool use has only previously been convincingly documented in chimpanzees among non-human species.

Veronika faces an additional physical constraint that makes her performance more impressive: she has no hands. According to the study published in Current Biology, she manipulates the brush entirely with her mouth, using her tongue to lift it and her teeth to hold it in place. Despite this, she anticipates outcomes, adjusts her grip, and controls the distal end of the tool with what the researchers describe as fine motor precision.

What It Says About Cows

The researchers are careful not to frame Veronika as an exceptionally gifted individual. Their interpretation runs in the opposite direction. Auersperg noted that assumptions about livestock intelligence may reflect gaps in observation rather than genuine cognitive limits. Cows are rarely studied in environments that would allow innovative behavior to emerge. Most are not given access to a variety of manipulable objects, do not live to Veronika’s age, and do not interact daily with humans in the way she does.

Wiegele’s approach to keeping Veronika — as a companion animal, not a production animal — appears to have created conditions that made this behavior possible. The researchers note that her long lifespan, daily human contact, and access to a physically rich environment were likely key factors. They now believe similar behaviors may exist in other cattle that have simply never been observed.

An Invitation to Look Again

The research team has put out a public call. Osuna-Mascaro and Auersperg are asking anyone who has observed cows or bulls using sticks or other objects for purposeful actions to contact them. They suspect that Veronika is not unique — only uniquely documented.

The Far Side comic got one thing right: cows and tools make for an unlikely combination. But the real absurdity, as the researchers write in their paper, may lie not in imagining a tool-using cow, but in assuming such a thing could never exist. Veronika has been proving otherwise, in a quiet barn in the Austrian countryside, for the better part of a decade.
