Cows Can Use Sophisticated Tools
Meet Veronika, the broom‑wielding cow igniting a “smart or hype?” stampede
TLDR: A pet cow named Veronika repeatedly used a broom to scratch specific spots, meeting scientists’ definition of tool use. Commenters are split between “cool finding” and “headline hype,” joking about Cow Tools, linking videos, and grumbling about trackers—turning one itchy cow into a full-on internet stampede.
Cows with tools? The internet’s barn doors flew open. A new study shows Veronika, a pet Brown Swiss cow, repeatedly grabbing a deck broom with her mouth and using the bristles for itchy hindquarters, then flipping to the handle for softer spots—checks the scientific box for “tool use.” Fans call it a moo-ment for animal smarts; skeptics roll their eyes at the headline. One critic snorts that calling this “sophisticated tools” is overcooked, arguing cows scratching with sticks isn’t rare. Another drops the classic Cow_tools meme, while a third goes full media watchdog: “Privacy Badger blocked 75 trackers.”
The drama hinges on expectation: the study frames this as rare outside primates, while the crowd wonders if we’re just rediscovering farm common sense. A commenter notes science always says animals are “more clever than we thought,” never the reverse. Meanwhile, the receipts exist—The Guardian posted video, fueling both awe and “okay, but it’s still scratching” energy. For non-scientists, the takeaway is simple: Veronika used a broom to help herself, not to change the world—think “self-care” tools, not cow MacGyver. But it’s a juicy reminder: maybe we’ve underestimated barnyard brains, and maybe the real battle is between cautious science and headline hype.
Key Points
- •A study in Current Biology documents a cow (Veronika) using a deck broom as a scratching tool, meeting the scientific definition of tool use.
- •Researchers ran 10 randomized trials, recording which end of the broom was chosen and how it was used.
- •Veronika gripped the broom with her mouth and consistently used the bristled end for hindquarters and the stick end for softer areas.
- •The behavior is classified as egocentric tool use and is framed as a notable cognitive feat in mammals outside primates.
- •Authors suggest cows’ cognitive abilities may be underestimated and that environment and prolonged human association may facilitate such learning.
