A 13-year-old brown Swiss cow named Veronika, who lives as a pet in a mountain village in southern Áustria, has developed the ability to use objects in the environment to precisely scratch herself. Pesquisadores of Universidade of Medicina Veterinária of Viena documented the behavior, classifying it as the first confirmed case of tool use in cattle. The study highlights the cow’s ability to adapt different parts of the same object depending on the region of the body.
Veronika resides in a pasture surrounded by forests and snow-covered mountains, in conditions that allow extensive interaction with the surroundings. Seu owner, a local baker, has kept the cow and its mother as pets for years. Essa freedom helped her perfect techniques over time.
The behavior gained scientific attention after the publication of a video showing the cow manipulating a rake. Especialistas visited the site and carried out controlled tests to validate the observations. The results indicate that Veronika does not just pick up objects, but uses them intentionally and mechanically to achieve specific goals.
Veronika’s idyllic life
Veronika spends her days in an environment rich in natural stimuli and objects available in the pasture. Gravetos, gardening tools and brushes are accessible, allowing for constant experimentation.
From the age of three, the cow began using sticks to relieve itching. Over time, he refined his movements, demonstrating progressive learning. The constant presence of blowflies in the summer intensifies the need for self-care, motivating the development of these skills.
The place where he lives, characterized by alpine landscapes, offers ample space to move around. Essa configuration differs from commercial farms, where animals face greater environmental restrictions.

Alice Auersperg, cognitive biologist, received mixed reports after releasing a book on the use of tools in animals. Most described common actions of domestic pets. One specific video, however, showed a cow manipulating a rake to scratch its back.
The team traveled to the property to observe Veronika directly. Antonio Osuna-Mascaró, postdoctoral researcher, attended the initial sessions. The recordings confirmed the precision of the movements, with the cow adjusting the position of the objects before application.
Subsequent tests involved placing a deck brush in random positions. Veronika demonstrated consistency in selecting and guiding the appropriate item for each situation.
Techniques observed by Veronika
Veronika begins the process by extending her tongue to roll the object and take it to her mouth. Then, fix it laterally between the teeth, ensuring stability during use.
It directs the chosen extremity to posterior regions of the body that are difficult to reach otherwise. Movements include dragging, pushing, and repositioning as needed.
- Use of bristles for upper areas, such as the lumbar and posterior areas, with intense friction actions.
- Use the smooth handle on sensitive lower regions, such as the udder and abdomen, with more delicate touches.
- Grip adjustments to reorient the object without letting go.
- Anticipate movements, repositioning before contact for greater efficiency.
These variations demonstrate adaptation to the physical properties of the object and the characteristics of the skin in each zone.
Applied definition of tool use
The adopted concept requires intentional manipulation of an external object to alter the environment or the body through a mechanical interface. Veronika meets the criteria by precisely controlling the functional end in relation to the target.
The observed flexibility includes exploring different properties of the same item. Essa multipurpose characteristic was known mainly in primates and some birds. The cow expanded the taxonomic scope to domestic ungulates.
Test statistics showed a significant association between the part of the object used and the target body region. The duration of the events remained similar regardless of the extremity used.
Tests carried out by researchers
The sessions involved 76 events recorded in seven rounds of ten trials each. The brush was positioned semi-randomly to avoid predictable patterns.
Veronika responded consistently, taking the object and applying it to posterior areas. Análises statistics confirmed a preference for bristles in upper regions and for handles in lower regions.
Slow-motion recordings revealed details of motor control. The tongue functioned as a right-handed element for initial positioning. Ajustes fines occurred during manipulation to optimize contact.
Implications for bovine cognition
The case of Veronika indicates latent capacities in cattle for physical problem solving. Condições Enriched environments favor the expression of these skills. In intensive breeding, spatial and object limitations reduce similar opportunities.
Previous research on cognition in livestock has focused on applied aspects such as productivity. Esse record expands understanding of technical flexibility in non-primate mammals.
Other domestic ungulates exhibit comparable behaviors in favorable contexts. The discovery suggests a need to reevaluate environments for production animals.
Context of tool use in animals
Several species employ external objects for specific purposes throughout evolution. Higher Primatas display complex variations, including item crafting. Aves how crows demonstrate planning in sequences of actions.
Elephants use branches to ward off insects or scratch inaccessible areas. Búfalos-water and goats have recorded isolated cases in natural environments. The behavior of Veronika represents advancement in showing hands-free multipurpose adaptation.
The domestication of cattle occurred more than 10 thousand years ago. Apesar from proximity to humans, records of advanced cognition remained scarce until now.
Details of the published study
The research appeared in the magazine Current Biology with detailed analysis of the events. Linear Modelos confirmed interactions between body region and type of extremity used. Testes exact of Fisher reinforced the significance of the associations.
Additional videos illustrated grip, anticipation and varied techniques. The observations took place in the field, preserving the cow’s natural conditions.
The authors emphasize that Veronika does not represent a unique exception among cattle. Fatores as available time and access to objects explain the manifestation of behavior.
Additional notes on motivation
The seasonal presence of insects acts as a main factor in the development of skills. Picadas generate persistent irritation in posterior areas. Veronika directs efforts exclusively to these zones.
Natural movements, such as rubbing against trees or fences, complement the use of portable objects. Preference for hand tools increases precision and reach.
Other cows on the property do not exhibit the same level of refinement. Veronika’s longevity and continued exposure contribute to the observed dominance.
Perspectives on animal welfare
Enriched environments allow expression of natural and cognitive behaviors. Escovas fixed mechanics are already used on some farms for hygiene. The case suggests potential for implementations that encourage active interaction.
Constraints in intensive systems limit similar manifestations. Aumentar variety of stimuli can benefit animals’ physical and mental health.
Future research could explore occurrence in other domestic contexts. Observações in different races and ages will help map prevalence.
