"The Duel" is a poem by American humorist and children's writer Eugene Field. It shares subject matter with the poem, a limerick in some versions and a seven-line extended limerick in others, "There Once Were Two Cats from Kilkenny."
Field claimed that the calico cat in the poem was inspired by the Ithaca Kitty.
It inspired the 1993 album and its title track, The Gingham Dog and the Calico Cat, by Chet Atkins and Amy Grant.
