The Ren & Stimpy Show, often simply referred to as Ren & Stimpy, is an American animated television series, created by Canadian animator John Kricfalusi. The show premiered on August 11, 1991 on Nickelodeon as part of its Nicktoons block along with Rugrats and Doug. The series focuses on the titular characters: Ren Höek, a psychotic chihuahua, and Stimpson J. Cat, a good-natured, dimwitted cat. The show ran for five seasons on the network. The show was rated TV-Y7 on Nickelodeon/Nicktoons, TV-PG on the Spike repeats, and TV-G on TeenNick.
The show has received critical acclaim and developed a cult following during and after its run, while some critics credit it for leading the way for satirical animated shows like Beavis and Butt-head and South Park, and playing a significant role in television animation. Throughout its run, The Ren & Stimpy Showwas controversial for its off-color humor, sexual innuendo, and violence, each of which contributed to the production staff's altercations with Nickelodeon'sStandards and Practices department. A spin-off for adult audiences, Ren & Stimpy "Adult Party Cartoon", aired in 2003 on Spike, but was cancelled soon after its debut. It ran on Nicktoons from May 1, 2002 to August 27, 2011. The original Nickelodeon series aired on The '90s Are All That on TeenNick on December 27, 2011. The original Nickelodeon series returned to The '90s Are All That as part of its Saturday line-up from February 9, 2013, to March 2, 2013.
