Cattle in General Terán, Nuevo León, Mexico

Alternative forms[edit]


Possibly from the fact that cattle let out to pasture may be expected to return for milking the next morning; thus, for example, a party that goes on “until the cows come home” is a very long one.

Alternatively, assuming a Scottish origin, the phrase may derive from the fact that cattle in the Highlands are put out to graze on the common where grass is plentiful. They stay out for months before scarcity of food causes them to find their way home in the autumn for feeding.

Reportedly, the first attestation is from The Times (Scotland):[1]

  • 1829, The Times:
    If the Duke will but do what he unquestionably can do, and propose a Catholic Bill with securities, he may be Minister, as they say in Scotland “until the cows come home.”
