Kathleen "Kat" Moon (née Slater) is a fictional character from the BBC soap opera EastEnders, played by Jessie Wallace. She was also played by Kate Peck in a flashback in 2001. Kat is the daughter of Viv and Charlie Slater (Derek Martin), and arrived with her sisters Lynne Hobbs (Elaine Lordan) and Little Mo (Kacey Ainsworth). Her daughter Zoe Slater (Michelle Ryan) is initially believed to be her sister as well until Kat reveals she was raped by her uncle Harry Slater (Michael Elphick) as a child. She later marries Alfie Moon (Shane Richie). She appeared in the show from September 2000 to November 2004, then returned in May 2005. She left again on 25 December 2005, and returned on 17 September 2010. Wallace was written out of EastEnders temporarily in January 2012 for a three-month period and the character will return on 7 June 2012.
Kat is described as "a bit of a floozy", "a bitch" and "very lazy". The EastEnders website says that as soon as Kat arrived in Walford with her "fake tan, heavy make-up and hoop earrings", viewers would know that Kat would bring a dose of "Viagra to the men of Albert Square". Richie revealed in an interview with This Morning that Kat and Alfie would be involved in an ongoing storyline, which he said is "going to be the biggest soap story in probably the history of soaps." At the end of 2010, Kat and Ronnie both give birth on the same day, but Ronnie's baby, James, dies and while Kat is in hospital and her baby, Tommy, is unattended, Ronnie swaps the infants. The storyline received over 6,000 complaints, making it the second most complained about EastEnders storyline. It was then decided to end the storyline earlier than originally planned.
