CatDog was a Nicktoon created in 1998, and marked a change in Nickelodeon. The show starred the hyperactive, slobby Dog and his suave, neat freak, attached friend Cat, in an Odd Couple-themed show. Cat and Dog live in a house shaped like half a bone and half a fish. The show has been criticized for marking the beginning of a change in Nickelodeon's style along with SpongeBob SquarePants.
