Horse owner paints her stallion to look like a zebra to ward off hungry horseflies. The non-toxic cattle-paint is in fact a ruse to prevent horseflies from biting the horse. She came up with the trick after learning that zebras never get bitten. Scientists have found black and white stripes are unappetizing to horseflies. Horseflies hate how stripes reflect light and prefer 'flat' light of dark coats. Neat!
