This cow uses tools like a primate—and scientists are stunned

In 1982, cartoonist Gary Larson created a Far Side comic called Cow Tools. It showed a cow with strange, useless objects labeled as tools. The joke was that cows were not smart enough to use tools.

Now, a real cow named Veronika is challenging that idea. A study in Current Biology reports the first time a pet cow has been seen using tools. This suggests cows might be much smarter than we thought.

Alice Auersperg, a cognitive biologist, said that assumptions about livestock intelligence might come from not observing them enough.

Meet Veronika, the Tool-Using Cow

Veronika is a Swiss Brown cow. She lives as aion animal with organic farmer Witgar Wiegele, who treats her like family.

Over ten years ago, Wiegele noticed Veronika picking up sticks to scratch herself. This behavior was later filmed and shared with scientists.

Auersperg immediately saw that this was not an accident. She said it was a clear example of tool use in a species rarely studied for its intelligence.

Testing Tool Use

Researchers set up tests to understand Veronika's behavior. They placed a deck brush in different spots and watched her.

Veronika consistently chose specific parts of the brush based on where she wanted to scratch. Her choices were not random. They matched the needs of different body parts.

Antonio Osuna-Mascaró explained that Veronika uses different parts of the same tool for different reasons. She also changes her technique depending on the tool and the body area.

Flexible Tool Use

Veronika showed clear patterns in how she used the brush. For large, firm areas like her back, she used the bristled side. For more sensitive areas on her lower body, she used the smoother handle.

She also changed her movements. She used broader, stronger motions for her upper body. For lower areas, her movements were slower and more precise.

Tool use means using an outside object to reach a goal. Veronika's actions fit this definition. Her behavior is considered flexible, multi-purpose tool use. This means she uses different parts of an object for different results.

This kind of behavior is very rare. It has only been clearly seen in chimpanzees among non-human species.

Overcoming Physical Challenges

Veronika uses tools on her own body, which is called egocentric tool use. While this is often seen as less complex than using tools on other objects, it still has challenges.

Cows do not have hands, so Veronika uses her mouth to handle tools. Despite this, she shows careful control. She seems to know what her actions will do. She adjusts her grip and movements to get the result she wants.

Why This Behavior Might Be Rare

Researchers think Veronika's unique living situation helped her develop this behavior. Unlike most cows, she has lived a long life in a rich and stimulating environment. She interacts with humans daily and has many objects to play with.

These factors likely gave her chances to explore and innovate. These opportunities are rare for most cows.

The researchers noted that Veronika did not make tools like the cow in the cartoon. But she chose, adjusted, and used one with great skill and flexibility. They suggest that thinking a tool-using cow could never exist might be the real absurdity.

Rethinking Animal Intelligence

This discovery is the first confirmed case of tool use in cattle. It adds to the list of species known to use tools. It also suggests that similar behaviors might exist but have not been noticed.

The research team is now studying what environmental and social conditions help such behaviors develop. They also ask others to report similar observations.

Osuna-Mascaró believes this ability might be more common than we know. He invites anyone who has seen cows or bulls using sticks or other objects for specific actions to contact them.
