She took the stage name Catz after discovering there was already another actress of the same name, and was inspired by seeing graffiti of cats in a phone box - although, ironically, she is allergic to them.

Her first significant TV role was in All Quiet on the Preston Front, the BBC comedy drama about a Territorial Army division, where one of her fellow cast members was Stephen Tompkinson, who she later starred alongside in DCI Banks.

It was while working on The Bill that she met her husband, fellow actor Michael Higgs. They have two children.

After The Bill, she played PC Cheryl Hutchins in all five series of The Vice, alongside the likes of David Harewood, Ken Stott and Tim Pigott-Smith, before sharing top billing with Lisa Faulkner in Murder in Suburbia, her third police role.

Whilst also making appearances in series such as Hotel Babylon and Agatha Christie's Marple, and being one of the lead characters in ITV's DCI Banks, it was her role in Doc Martin, as his wife Louisa Ellingham, that established her as one of the most frequently seen faces on British TV screens.

Away from acting, she is a keen musician, singing with a band called Sapphire.
