The nickname for a woman is more than 10 years younger than her man. Whether she is dating him, in a relationship, or married, a kitten is interested primarily in the emotional security, status and power that goes along with being with an older man. Unlike a trophy bride who is considered beautiful only on the exterior and interested primarily in financial security, a kitten is considered smart and independent in her own right and is interested in the security a father figure provides. Not to be confused with a cougar or a puma.
Celebrity examples include Catharine Zeta-Jones and Michael Douglas, Calista Flockhart and Harrison Ford, and Katie Holmes and Tom Cruise.
