(Mr.) CatDog is an American animated television series, hence the name of this character, which premiered on April 4, 1998 and ended on June 15, 2005. The series was created for Nickelodeon by Peter Hannan. The cartoon "Winslow's Documentary" was also shown in theaters with The Rugrats Movie. The series depicts the life of conjoined brothers, with one half being a Cat and the other a Dog. Nickelodeon at first ordered 40 episodes and planned to debut it in spring 1998. Nick produced the series from Burbank, California, United States.
Towards the end of the series run, a made-for-TV film was released, titled CatDog: The Great Parent Mystery. Reruns are played on Nicktoons. The series is produced by Nickelodeon Animation Studio and Peter Hannan Productions and is currently being released on DVD.
The series follows the adventures of CatDog, a conjoined twin hybrid of a cat and dog with two heads (one at either end of its single body) and no tail or hind legs.
The series, created by Peter Hannan, was developed as the next Nicktoons production and produced from Nickelodeon animation studio in Burbank, California. Hannan served as executive producer. This was part of Nickelodeon's $350 million investment in original animation over the next five years after the series' inception.Albie Hecht, Nickelodeon's senior vice president of worldwide productions, said that the creators planned for the series to "really play off of kids' sympathies" by portraying the characters as experiencing "the worst of both worlds".
Hannan said he was inspired by CatDog by watching neighborhood cats and dogs occasionally fight each other, and thought that it would be great to make conjoined twinned Cat and Dog to see how both of the animals would fare against other things. The idea of them being conjoined twins came from Hannan watching several news stories on TV about conjoined twins living a normal life conjoined together. Both aspects he claimed, initially developed the idea of CatDog.
The series revolves around Cat and Dog, who share the same body, and although they are best friends and brothers, they have very different personalities, similar to The Odd Couple mixed with elements of Laurel and Hardy and Abbott and Costello. Cat is very cultured while Dog is very fun-loving and enjoys chasing garbage trucks, chasing cars, and exploring many things in which Cat does not want to take part. Dog enjoys eating at fast food restaurants (such as Taco Depot),whereas cat does not.
The series was followed by the television film "The Great Parent Mystery," which premiered in 2001.
CatDog is known as "Gatoskylo" in Greece and "Kattehund" in Norway.
Catdog was also a playble character in Nicktoons Racing.
