Valerie Brannigan was the wife of the Catkind Thomas Kincade Brannigan.
Valerie had travelled with her husband for twelve years, stuck on the New New York motorway in their car. Despite being of different species, they had several two-month-old children who looked like regular kittens. Later, when the Face of Boe released the cars into the city, Valerie sang “Abide With Me” as The Doctor told Martha about Gallifrey. (Gridlock)
When New Earth was invaded by the Judoon and Cybermen alliance, she was upgraded into a Cyberman and later died when The Doctor defeated them. (In-Flight Entertainment)
