Cows
Cows can use tools. Dairy still takes the calf away.
305MCows killed in 2024 (FAO)
About 305 million cows were killed in 2024 — about 835,000 every day. A cow named Veronika uses a broom as a tool — the bristled end for most of her body, the stick end for softer spots. Mothers and calves recognize each other’s voices; in dairy, that bond is broken within hours so the milk can be sold. Heifers who solved a puzzle showed higher heart rates and more ear movement at success than cows who got the same treats without having to figure anything out — they noticed when they got it right. We do not have to harm or eat animals at all.

Cows killed for food in 2024 (FAO)
About 835,000 cows every day — mothers, calves, and dairy cows whose calves were taken first.
Who they are
The main points first. Every claim is tied to a source below.
Tool use in a cow
Veronika, a pet cow in Austria, uses a deck brush to scratch herself — the bristled end for most of her body, the stick end for softer spots. Current Biology (2026) described this as flexible, multi-purpose tool use, which is rarely seen outside primates. It is one cow, but it is enough to retire the idea that cows are dumb.
Mothers and calves recognize each other's voices
In playback experiments, a cow answers her own calf's call, and the calf answers hers — looking, turning, walking toward the speaker. In dairy systems, that calf is usually taken within hours so the milk can be sold.
They notice when they figure something out
Heifers given a puzzle they could solve showed higher heart rates and more ear movement when they got it right than cows who got the same treats without having to solve anything. They seemed to care that they had figured it out.
They form friendships
Cows form preferred social partners. Reviews of cow psychology describe personality, play, and stress when a companion is gone. Beef cows live short lives. Dairy cows live longer ones with the same ending — and a calf taken in between.

Flexible use of a multi-purpose tool by a cow
Veronika preferred the bristled end of a broom but switched to the stick end for softer lower-body areas — adaptive deployment of one object for different functions. First scientific report of tool use in cows. Single animal: a demonstration, not a herd survey.

Do cows use tools? This one does.
News write-up of the Veronika study: cows have not been celebrated for their smarts; flexible tooling is rare; the authors argue farm-animal cognition needs a reassessment.

Mother–offspring recognition via contact calls in cattle
Cows were more likely to look, turn, or walk toward playbacks of their own calf than of an unfamiliar calf. Recognition is bidirectional.

Emotional reactions to learning in cattle
Holstein-Friesian heifers who learned an operant task showed greater heart-rate and behavioral responses at success than cows who received the same rewards without having to learn — evidence they evaluate their own learning.

The psychology of cows
Review: cows show personality, social complexity, learning, and emotion. They are someone. The paper was written because the science was already there and the public picture was not.

Global slaughter — cows
FAOSTAT 2024: about 305 million cows slaughtered. Faunalytics' full land-animal total for 2024 is 87.9 billion. Cows are a minority of bodies and a majority of the land and climate bill.
