What does cathouse mean?
Cathouse is an informal noun referring to a brothel, or house of prostitution. The word is formed transparently from 'cat' plus 'house,' though its connection to cats is figurative rather than literal — it belongs to a family of slang terms in which 'cat' carries connotations of licentiousness. Most strongly associated with American English, it evokes the saloons and red-light districts of the nineteenth-century American West and appears frequently in historical fiction, Westerns, and accounts of frontier towns. Its register is colloquial and mildly coarse: less clinical than 'brothel' and less vulgar than some alternatives, making it a common choice for writers seeking period color without explicit language. Although a literal sense meaning a shelter or house for cats occasionally surfaces, this reading is rare and generally considered a humorous or mistaken interpretation. Today the word is encountered mostly in historical or literary contexts rather than everyday speech.
A house of prostitution; a brothel.
"The sheriff claimed he was raiding saloons that night, but everyone knew he was really headed for the cathouse."
Informal and chiefly North American; common in Western and historical contexts.
Rarely, a house or enclosure for keeping cats.
"She converted the garden shed into a cathouse for her growing clowder of rescues."
Literal sense; much rarer than the slang sense and often used playfully.
Regular plural formation.
"By the turn of the century, several cathouses operated openly on the edge of town."
Despite sounding like a shelter for kittens, a cathouse is actually an old American slang term for a brothel — one reason Victorian euphemism and frontier slang make English so treacherous.
