In 2003, Sutton found inspiration from the internet "where apparently people say that every time you masturbate God kills a kitten". From that statement, he developed a comic piece about "a young man's emotions and feelings, from the moment he's a baby tugging at his cock onwards." In August 2003, he performed the one-man Killing Kittens show at Edinburgh's Underbelly. Sutton followed up Killing Kittens with a second autobiographical show Pandora's Lunchbox in 2006. Following an acclaimed performance as william Blake in Peter Ackroyd's BBC television series The Romantics, Sutton joined the cast of Albion Rising at St. Giles in the Fields Church, London, in April 2007.
