is an original animated show from Nickelodeon. It was created by Peter Hannan.
The show revolves around Cat and Dog who share the same body, and although they are best friends/brothers, they have very different personalities. Cat is into Opera, cleanliness, money, and anything else that will please him. Dog is very fun loving and loves eating, chasing cars, exploring, and just about anything else a dog would love.
They live in house that is in shape of a fish and bone with their roommate Winslow, a smart mouth blue rat who loves giving CatDog grief. In the city of Nearburg, the two inadvertently cause problems for the residents that live there. The Greaser Dogs, a gang of bullies whose names are Cliff, Shriek, and Lube, always bullying Cat and Dog, but mostly Cat. So as you can see, CatDog lives a tough life with a lot of tough people out to get them. But at least they're never bored.
