pussy (1) Look up pussy at Dictionary.com
"cat," 1726, dim. of puss (1), also used of a rabbit (1715). As a term of endearment for a girl or woman, from 1583 (also used of effeminate men). Pussy willow is from 1869, on notion of "soft and furry;" pussyfoot (v.) is from 1903, originally the nickname of stealthy Oklahoma prohibition agent W.E. Johnson (1862-1945).
pussy (2) Look up pussy at Dictionary.com
slang for "cunt," 1879, but probably older; perhaps from O.N. puss "pocket, pouch" (cf. Low Ger. puse "vulva"), but perhaps instead from the cat word (see pussy (1)) on notion of "soft, warm, furry thing;" cf. Fr. le chat, which also has a double meaning, feline and genital. Earlier uses are difficult to distinguish from pussy (1), e.g.:
"The word pussie is now used of a woman" [Philip Stubbes, "The Anatomie of Abuses," 1583]
But the use of pussy as a term of endearment argues against the vaginal sense being generally known before late 19c., e.g.:
" 'What do you think, pussy?' said her father to Eva." [Harriet Beecher Stowe, "Uncle Tom's Cabin," 1852]
Pussy-whipped first attested 1956.
