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:

    It is restful, tragedy, because one knows that there is no more lousy hope left. You know you’re caught, caught at last like a rat with all the world on its back. And the only thing left to do is shout—not moan, or complain, but yell out at the top of your voice whatever it was you had to say. What you’ve never said before. What perhaps you don’t even know till now.
    Jean Anouilh (1910–1987)

    I am ashamed to see what a shallow village tale our so-called History is. How many times must we say Rome, and Paris, and Constantinople! What does Rome know of rat and lizard? What are Olympiads and Consulates to these neighboring systems of being? Nay, what food or experience or succor have they for the Esquimaux seal-hunter, or the Kanaka in his canoe, for the fisherman, the stevedore, the porter?
    Ralph Waldo Emerson (1803–1882)

    Your rat tail is all the fashion now. I prefer a bushy plume, carried straight up. You are Siamese and your ancestors lived in trees. Mine lived in palaces. It has been suggested to me that I am a bit of a snob. How true! I prefer to be.
    Raymond Chandler (1888–1959)
