Study documents first flexible tool use in a cow: full analysis

A Swiss Brown cow named Veronika is forcing a rethink of what scientists, and perhaps the wider animal-health field, assume about cattle cognition. In a January 19, 2026 paper in Current Biology, researchers reported the first documented case of flexible tool use in cattle after observing Veronika use a deck brush in different ways to scratch different parts of her body. The case later drew broader attention through a March 26 ScienceDaily write-up and follow-on coverage in Nature, National Geographic, and other outlets. (sciencedirect.com)

The background matters here. Tool use has long been treated as a marker of advanced cognition, first in humans, then in a relatively small set of other species. According to the study authors, cattle cognition research has remained sparse despite millennia of domestication, and much of it has focused on applied questions tied to productivity or welfare rather than broader cognitive capacities. Veronika’s case came to researchers’ attention after her caregiver, Austrian organic farmer and baker Witgar Wiegele, recorded her repeatedly picking up sticks and brush-like objects to scratch herself. That prompted Alice Auersperg and Antonio Osuna-Mascaró of the University of Veterinary Medicine Vienna to conduct systematic observations. (sciencedirect.com)

The key finding wasn’t simply that Veronika manipulated an object. It was that she appeared to use the same object flexibly. In the researchers’ tests, the cow used the brush end for broader, scrubbing contact on upper-body areas, while the wooden handle was used more precisely on lower-body or more sensitive regions. Coverage of the paper notes that the behavior was repeated across many trials, and that researchers initially thought use of the handle might be accidental before concluding it was functionally distinct. That distinction is important because multi-purpose use of a single tool is considered especially rare in the animal kingdom. (sciencedirect.com)

The university press materials framed the report as a challenge to longstanding assumptions about livestock intelligence. Auersperg said the findings suggest that what looks like limited cognition in farm species may partly reflect limited opportunity for observation and expression. In outside commentary, animal behaviorist Lindsay Matthews of the University of Auckland, who was not involved in the work, said the case underscores how readily people accept intelligence in some species while overlooking it in others. Other coverage also pointed to anecdotal reports of branch use in cattle, suggesting Veronika may not be unique so much as unusually well documented. (sciencedaily.com)

Why it matters: For veterinary professionals, this is less about whether cows will routinely join the short list of canonical tool users and more about what the case says regarding cognition, welfare, and clinical observation. If cattle can show more flexible problem-solving than commonly assumed, then housing, enrichment, handling, and pain or discomfort assessment may all benefit from a more behaviorally informed lens. Animals with greater environmental agency may reveal needs, preferences, and coping strategies that are easy to miss in highly standardized systems. The study does not prove that tool use is widespread in cattle, but it does strengthen the argument that underestimation of bovine cognition can shape both research priorities and everyday care.

There are also practical limits to keep in view. Veronika is a single companion cow living in an unusually enriched setting, not a representative sample of commercial cattle populations. That means the report should be read as a proof of capacity, not prevalence. Still, for clinicians and behavior-minded veterinary teams, single-animal observations often matter when they open a new line of inquiry, especially in species that have historically received less cognitive research attention than dogs, horses, parrots, or primates.

What to watch: The next phase will likely involve efforts to identify similar cases, test cattle with different objects or enrichment setups, and determine whether flexible tool use is rare, underreported, or simply overlooked in conventional management environments. If more cases emerge, this paper could become a reference point in broader discussions about cattle welfare standards and the behavioral needs of animals in both companion and production settings.
