When does CatDog return?

CatDog is an American animated television series created by Peter Hannan for Nickelodeon. The series follows the zany hijinks of golden-furred conjoined conjoined brothers of different species, with one half of the resultant animal being a cat and the other a dog. The first episode aired on April 4, 1998, following the 1998 Kids' Choice Awards, before the show officially premiered in October of that year. It ended on June 15, 2005, after a total of 66 aired episodes over seven years, plus two produced episodes never aired.
The series revolves around Cat and Dog, a golden-furred conjoined twin hybrid of a cat and a dog with two heads and shared body, with no tail or hind legs. The series takes place in Nearburg, a town dominated by anthropomorphic animals and the occasional humanoid.
