CatDog is an American animated television series, hence the name of this character. The show aired for 3 seasons between 1998 and 2005 on Nickelodeon. The series depicts the life of conjoined brothers, with one half being a Cat and the other a Dog. Nickelodeon at first ordered 66 episodes and planned to debut it. 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 currently played at TeenNick's "The '90s Are All That". The series is produced by Peter Hannan Productions and Nicktoons.
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.
CatDog is known as "Gatoskylo" in Greece and "Kattehund" in Norway.
CatDog was also a playable character in Nicktoons Racing.
