Petey is the former main antagonist of the Dog Man series, until Lord of the Fleas, where he redeems himself and gets replaced with grandpa. He first appeared in the Super Diaper Baby series. Recently, he's been a protagonist of the series, and he seems to have replaced Dog Man as the main focus.

Official Description (can be found in Mothering Heights)

Once known as the World's Most Evilest Cat, Petey is now working on becoming a better version of himself.

STRENGTH: Intelligence

WEAKNESS: Easily Annoyed



Petey is an anthropomorphic ginger cat with black stripes from his shoulders to his tail. As of the book A Tale of Two Kitties, his right cheek only has two whiskers compared to the three whiskers on his left. Like every other character Dav Pilkey has drawn, Petey‘s eyes are simple black lines. The tip of his long tail is flat at the end for an unknown reason. However, Grampa knows what happened to his tail.


Petey is a stereotypical "grumpy" cat, generally having a short temper. He is very clever, as he is capable of making machines and robots.

In earlier books, Petey only really cared about himself and his inventions. He also had a bit of an arrogant side as well, evidenced by how it would annoy him when someone else (i.e. the Mayor) tried to do evil in his self-proclaimed city because he felt that he was the only one allowed to be evil in his city.

Deep down, however, Petey has a good side, which Li'l Petey was able to bring out. He becomes a good guy again starting in Dog Man: Lord of the Fleas when the F.L.E.A.S. arrive to destroy Li'l Petey.

This is due to Li'l Petey's compassionate and loving ways towards him. When Petey was controlling his robot, Li'l Petey told Petey his own motivational quote, which proved right.

Petey has stopped being evil since Dog Man: Lord of the FLEAS. He finds a strong bond with Dog Man, Li'l Petey, and all of his friends, as he now feels like part of the team.

Not a lot is known about Petey's kitten life, but we do know that he had a dark life back then. He joined the Critter Scouts, and had lived with his mother and father, until he was banned from the Critter Scouts after his friends Piggy, Crunky, and Bub blamed him for causing trouble. This ignited the fire for Petey to later become evil. The Critter Scouts was later closed down shortly after Petey called the Animal Rights Union, and protests started against the organization, shutting it down within a week!

Shortly after Petey's father left, he and his mom moved to Happy Home Shelter. They did not have much food or money that Petey said but they did have love and hope.

Additionally, Petey's mother got sick, and later died. This left Petey an orphan, and not much is known from that point. It is unknown how he got a flat tail, but his father almost exposed how this happened in For Whom the Ball Rolls. He somehow was acquired by Dr. Dilbert Dinkle and became his pet cat. He is no longer owned by him since he is now on Uranus. Petey's first jail was Jail 4 Cats. Finally when he was free, no one liked him, never letting him forget who he previously was.


Petey resides mostly in his lab (formerly called Petey's Secret Lab, which is now called Petey & Son). The building contains his secret library, a bathroom, and, of course, his very huge lab, where he makes new inventions every day. He has many secret rooms in his lab, which he mentioned in Dog Man: For Whom the Ball Rolls. In Mothering Heights, it is destroyed by the Sippy Cups, and he now temporarily resides with Dog Man.


  • Petey is based on Dav Pilkey, the author and illustrator of Dog Man. He had reading and behavioral problems in his childhood, and his mom, Barbara (which loosely inspired the character Li'l Petey) helped him, like going to the library to let him choose whatever books he was interested in, and letting him focus on his good behavior.
  • According to Dav Pilkey, he takes the role of Sydney Carton, a character in A Tale of Two Cities, the book in which A Tale of Two Kitties is based upon. Therefore, he says quotes that Sydney Carton says in said novel.

    • Petey was first featured in Super Diaper Baby 2, which was released before Dog Man. While the real Petey appears as one of the villains, he doesn't play a huge role in the entire story. Therefore, his paper counterpart is the main antagonist in Dog Man: Unleashed.

      • Petey's top left whisker hasn't regrown since.

  • Li'l Petey: Since he is now a father, he is protective of him and doesn't want him put in danger. He will do anything to keep him safe, and loves him more than anything.
  • 80-HD: In A Tale of Two Kitties, he used the former to retrieve Li'l Petey. In Grime and Punishment, 80-HD breaks three walls and the door of Petey and Son, prompting Petey to make him fix it in the next book.
  • Chief: Chief always thought Petey had a hidden good side somewhere, and he was proven right in Lord of the FLEAS.

  • Zuzu: They are somewhat friends, but sometimes they don't understand each other.
  • Flippy: Ever since the events of A Tale of Two Kitties, Petey wasn't very fond of Flippy, calling him a 'crazy fish'. He has grown to accept the latter since the end of Fetch-22.

  • Piggy, Crunky, and Bub: Before Petey closed down the Critter Scouts, they seemed to be good friends. However, after the events of Lord of the FLEAS, they are now mutual enemies.
