CatDog is an American animated television series created by Peter Hannan for Nickelodeon. The series follows the life of yellow conjoined brothers of different species, with one half of the resultant animal being a cat and the other a dog. Although they are best friends and brothers, they have very different personalities. Cat is very cultured, while Dog is very fun-loving. Dog enjoys chasing garbage trucks, cars, and exploring many things that Cat does not want to be involved with. Dog enjoys eating at fast-food restaurants (such as Taco Depot), whereas Cat does not. The series takes place in Nearburg, a town dominated by anthropomorphic animals and the occasional humanoid.
