Cat is the main protagonist of the Nickelodeon animated series CatDog. He often devises plans to trick Dog into getting what he wants, such as making Dog smarter in an attempt to have more in common with him, or having him win a dog sledding contest by training him in a very hard and militaristic manner, and usually, as a result of his greediness and selfishness, these schemes all blow up in his face. The character is the underdog of the two. Life has been hard for the both of them, as they have been shunned by society due to their awkward appearance, but Cat always seems to get the short end of the stick in the situations, especially faced with the Greaser Dogs. With his brains and constant ridiculing from the rest of the characters, he is the more defensive and short tempered of the two. Despite his quirks and spats with Dog, he loves his brother with his whole heart. He cares so deeply that he ends up helping Dog in the end once his guilty conscience gets to him.
