Veronika’s improvised grooming device has caused great surprise – but that tells us more about humans than cows
I have a farmer friend who regularly regales me with colourful stories of her cattle. Take the time when a beef cow called Noisette used her tongue to pull back the catch on the door of her pen so she could steal cattle nuts from the nearby feed bin. Or the time when she did it again, not to let herself out, but seemingly to stand back and watch as her freed compatriots “mooched around and caused mayhem.”
Where others see a herd of cows standing around looking bored, my friend sees a soap opera, with characters and plot twists. Cows, she tells me, learn quickly, bore easily and have an indefatigable penchant for mischief.
