Researchers worked with farmers in Botswana, Africa, who painted cattle in 14 herds suffering from regular lion attacks.
The scientists painted one-third of each herd with an eye design on the cows’ bottoms, one-third with simple cross marks, and the rest of the cows were left without any markings.
They found that cattle painted with fake eyes were significantly more likely to survive than unpainted or cross-painted control cattle within the same herd during the four-year study.
