hey have an unusual double coat of hair. On the outside is the oily outer hair - the longest of any cattle breed - covering a downy undercoat.This makes them well suited to conditions in the Highlands, which have a high annual rainfall and sometimes very strong winds. Their skill in foraging for food allows them to survive in steep mountain areas where they both graze and eat plants that many other cattle avoid. They can dig through the snow with their horns to find buried plants.
