Rats are various medium-sized, long-tailed rodents of the superfamily Muroidea. "True rats" are members of the genus Rattus, the most important of which to humans are the black rat, Rattus rattus, and the brown rat, Rattus norvegicus. Many members of other rodent genera and families are also referred to as rats, and share many characteristics with true rats.

Rats are typically distinguished from mice by their size; rats are generally large muroid rodents, while mice are generally small muroid rodents. The muroid family is very large and complex, and the common terms rat and mouse are not taxonomically specific. Generally, when someone discovers a large muroid, its common name includes the term rat, while if it is small, the name includes the term mouse. Scientifically, the terms are not confined to members of the Rattus and Mus genera, for example, the pack rat and cotton mouse.

Famous quotes containing the word rat:

    Everybody gets pinched but you did it right. You told them nothing and they got nothing. You learned the two greatest things in life: Never rat on your friends and always keep your mouth shut.
    Nicholas Pileggi, U.S. screenwriter, and Martin Scorsese. Jimmy Conway (Robert DeNiro)

    A rat crept softly through the vegetation
    Dragging its slimy belly on the bank
    While I was fishing in the dull canal
    On a winter evening round behind the gashouse
    Musing upon the king my brother’s wreck
    And on the king my father’s death before him.
    —T.S. (Thomas Stearns)

    When a rat crosses a street, everyone shouts and beats it.
    Chinese proverb.
