Petey TheCat, better known as Petey the Cat, is one of the two deuteragonists (alongside his younger clone and son Li'l Petey) of the Dog Man franchise.
He is an evil anthropomorphic cat with a tragic past in which his abusive father betrayed him and his dying mother Grace when he was just a kitten. Since then, he becomes an incredibly intelligent inventor, who creates all sorts of technology to commit crimes. However, thanks to his son Li'l Petey, he had a change of heart and became a helpful ally to the heroes. He is the former arch-nemesis of Dog Man before turning good and the current arch-nemesis of both his childhood friend, Piggy, and his father.
He was played by Jamie LaVerdiere in Dog Man: The Musical. In the 2025 film adaptation, he was voiced by Pete Davidson, who also played Blackguard in The Suicide Squad.
Personality[]
When Petey was first introduced, he comes off as a one-dimensional villain who loves causing trouble just for his own amusement. He shows no care for others and only treats his clone/son Lil' Petey as disposable and tried to turn him into the same evil cat as himself. He is extremely intelligent and cunning, being able to build many large and complicated robots such as 80-HD. Petey also gets very easily annoyed when others such as his inmate Big Jim and his clone try to get into a friendly conversation with him.
He is also shown to be nasty and teasing. Often in his debut, Super Diaper Baby 2: The Invasion of the Potty Snatchers, he teased Dr. Dilbert and made fun of his plans (and breath). He then betrayed him because of how badly Dilbert treated him and tried to destroy the world using Dilbert's robot Mecha-Kitty. He also disliked Dog Man, a reference to the cat-dog rivalry. When Super Diaper Baby and Diaper Dog take him to jail, he's excited at first (due to the cat litter craze), but whenever he's arrested thanks to Dog Man, he almost always ends up saying “Rats!"
However, as Book 5 would reveal, a part of Petey's turn to evil stemmed from the fact that he was betrayed by his friends and fellow Critter Scouts when they were little. After Petey accidentally broke Piggy's glasses and started a fire, the scouts blamed him when the scout teacher caught them. After this, Petey's scout badges and goods deeds were removed and he was kicked out of the scout group. This made Petey believe that doing good was for nothing and nobody would care if he did good.
In the same book, Lil' Petey would reach out to his father and encourage him to do good by helping Dog Man defeat the FLEAS (Petey's former childhood scout friends). From that book and moving forward, Petey would become a better cat due the living representation of his mother's love (his son) believing in him and never giving up on him despite all his past misdeeds. Despite his redemption, he still gets easily annoyed when his son and Molly the Tadpole disturb him, and is still somewhat nihilistic about the world. But he still believes in good virtues such as love and forgiveness, such as when he forgives his abusive father.
As the series progresses, more of Petey's past life is shown, revealing that he is a traumatic cat, with his friends betraying him in the Critter Scouts as said above, as well as his mother dying of an illness not much longer after his abusive father betrayed the both of them. This shows why we went into the path of villainy: to release his anger of his own past onto the world.
In the movie, Petey retained most of his personality in the books, as DogMan’s old foe. He is a villain who only cares about defeating DogMan and trying to take over the world. Although mostly a villain, he deeply cared for his son, Lil’ Petey, as shown when Lil Petey would draw his father and him. He is also shown to be protective since when Flippy tried to hypnotize Lil’ Petey, Petey yelled at Flippy to leave his son alone. Petey is also shown to be remorseful and honest, as seen when he tells Lil’ Petey his villainy is a result of the abuse he endured from his father as a kitten.
Appearance[]

Petey's general appearance before the events of A Tale of Two Kitties, where he plucks out one of his right whiskers.
Petey resembles an orange tabby cat with horizontal black stripes across his body. For an unknown reason in his first appearance, he was shown significantly shorter than what he is in the Dog Man series. He has a flat tail for an unknown reason, though it is very likely the faulting of his father. Unlike other cats in the series, he has five whiskers after plucking one of his right whiskers off to create Li'l Petey.

(from left to right) P.T. Duckhat, Miss Suspiscionflame, and Dr. Katz.
Excluding his main design, Petey has had some other appearances, exclusively in the disguises he makes. His first ever disguise, under the alias of "P.T. Duckhat", showed him as a clown with white makeup and red cheeks. As the name suggests, he wears a hat resembling a duck. His second disguise in the series, titled Miss Suspiscionflame, disguises Petey as an old lady with white makeup and a grey hairdo. "She" is also seen with a purple umbrella usually and wears green attire and high heels. "She" can also be seen with clear glasses on. His final disguise, titled Dr. Katz, disguises Petey to not be a tabby cat but rather a dark grey cat with a light grey mustache and glasses. The outfit also makes him portray as slightly overweight, wearing a white labcoat.
Despite appearing as an adult throughout the series, as his flashbacks would reveal, his younger self would appear exactly like that of Li'l Petey, with a round head with a slightly curved chin. In his times as a Critter Scout, he is shown wearing a blue and yellow hat with the Critter Scouts logo printed on it, as well as a yellow sash with countless of badges going through his blue collar. Later in his life, Petey would continue to look like Li'l Petey, however he would appear with a white badnage on the tip of his tail, and eventually, have his iconic flat-tip tail.
During his teenage years, Petey is shown to have grown the height he did in his first appearance. However, he still has the curved chin, though the chin is shown to be smaller than when he was a young child, showing the process cats have in the universe to have a completely round head.
In the film's adaption, he looks the exact the same in the comic books, though his fur has more details and has green color under his eyes.

Trivia[]
- Despite only appearing in the Dog Man comics, Petey is considered one of the most popular and recurring antagonists in the Captain Underpants universe.
- Despite being generally considered as the deuteragonist of the Dog Man books, in recent ones he is shown to have more page time and character development than Dog Man.
- He was briefly forced to return to being evil in the twelfth book of Dog Man, The Scarlet Shedder by Dr. Scum.
- While it is not confirmed and Petey may still be alive, it is implied that he created a robot doppelgänger of him that murdered him sometime before the events of Dog Man: The Bark Knight Cometh, as when Chief sees the doppelgänger, believing it to be Petey, he exclaims that he thought he was dead.
- Out of every book (excluding the Cat Kid Comic Club series), Big Jim Begins is the only one since his debut that he does not appear in.
- Pete Davidson's casting as the voice of Petey in the 2025 film adaptation of Dog Man is interesting, given the fact that he and Petey have similar given names.
