Oggy's defining trait is arguably his laziness, enjoying watching television, eating, and, on a couple of instances, listening to music. As something of a neat freak, he feels compelled to have his residence clean and orderly and periodically performs household tasks. According to online descriptions, he is fond of the ideal home, game shows, listening to polka records, and eating chips in the bath. In addition, he is mentioned to fantasize about attaining a self-cleaning oven or a 12 gear vacuum on "The Wheel of Fortune". He also displays a love for gardening and board games.
Despite his slothful nature, Oggy is a diplomatic and easy-natured cat. He often displays kindness toward animals and often takes care of them. Indeed, he could not bring himself to kill an octopus in one episode. In spite of appearing to have a calm demeanor, Oggy will retaliate without hesitation when provoked (predominantly by the cockroaches).
In several episodes, Oggy has been shown to have five prime phobias: hydrophobia (fear of water), murophobia (fear of rats & mice), trypanophobia (fear of needles), acrophobia (fear of heights), and aviophobia (fear of flying). In Season 4, Oggy becomes a more outside and playful cat, as he is seen outside of his house in his yard for most Season 4 episodes.
Oggy has a blue overweight body, a red jellybean-like nose which can be removable at times, a pink tongue, a grey tummy with a squiggly belly-button, whiskers on three yellow circles, black pointy ears, white gloves, and white feet which has resembled to be shape of a teddy bear.
He also has an oblong shaped tail and whenever his gloves removed, his hands are barely blue. In "Little Tom Oggy", he can use his nose as a flashlight in dark places. He can't feel stuff when surprised. This is only shown in "Jealousy", "Fame & Glory", "Showtime!" and "Olivia." Oggy always wields a flyswatter in his hand which is always red, although in some episodes it's grey or yellow.
In Artsy Oggy, he wore a black barrete for painting.
Oggy owns an orange 1960-1970 Volkswagen Beetle that is mostly used in Season 4 but it can be seen in some episodes of Season 3. The car was originally Bob's. But apparently Bob owns a different car as seen in Grease-Monkey Oggy and To Serve and Protect. He is seen on other vehicles such as a Vespa Scooter in Hit the Road Oggy!, Saturday Black Fever, The Joker Joked and Control Freak. and a 1960 looking coupe seen in The Hiccup.
He also owns a 2004 Toyota Hiace Purple with a front end of a Hyundai Starex which was seen in episodes The Pumpkin that Pretended to be a Ferrari.
Jack is Oggy's cousin. Oggy and Jack almost act like life partners to each other. Jack almost always decides to help Oggy when he is in trouble, whether it be the Cockroaches, getting launched to space or getting trapped in the internet. However their relationship isn't perfect. At times, Jack will act more villainous and overall insane, this will always lead to Oggy trying to stop him from going any further.
The new girl next door neighbor. He falls in love with Olivia. in the episode "Olivia", he saved Olivia's life, making Jack and Bob jealous of him. She is a white cat. He is mostly nervous when he is with her, while Olivia doesn't feel nervous about the two liking each other and have feelings for each other. But, after a few episodes in Season 4, he doesn't seem to feel as nervous as before. In "Oggy Is Getting Married!", both Oggy and Olivia are married together. In almost every episode where they appear together, she kisses him on the cheek. Occasionally, they end up kissing each other on the lips.
Oggy holds an intense grudge against Dee Dee, Marky, and Joey, which goes back to even when he was a baby (revealed in the episode "It's a Small World" and "Itsy-Bitsy Oggy). Throughout the course of the series, Oggy has chased the insect trio innumerable times. While he has lost and fell victim to the cockroaches in quite a few episodes, he can reign victorious and defeats them (especially in later seasons). Occasionally, however, Oggy is forced to work together with them, especially when Jack is played out as the antagonist, like in: "The Dictator", "General Jack", "Life's a Beach", and "Oggy's Beach Club". Oggy will sometimes have sympathy towards the Cockroaches. In "Oggy and the Babies" and "Oggy and the Kittens" he pleads to Jack to spare their lives and in "Lost in Space", "Space Journey" he decides to rescue the Cockroaches from suffocating in space despite being a constant nuisance to him. In short, Oggy has a peculiar love/hate relationship with the cockroaches. In fact, he has also learnt that without them, his life would be very boring, this is proved in episode So Lonely and Alone at Last, where he gets rid of the roaches, but later he regret for them and realizes that his life isn't the same without them.
Oggy and Joey are usually enemies. At times however, they form a villainous friendship when they both end up in trouble. Episodes like "Virtual Voyage", "Cyber-Oggy", "Mission to Earth", "Welcome to Mars" and "Journey to the Center of the Earth" show them having to work together to save each other. In "Ugly, Dirty and Good" when Joey regresses back into a child, Oggy takes him under his care and is genuinely distraught when they go back to being enemies after finally he recovers. Glimmers of their positive relationship still stands however, in "For Real!" they hug after turning back into their real selves and in "Inspector Dee Dee", he is more than happy to give back Oggy's swatter after it was stolen by an octopus. Oggy and Joey's relationship is the most prominently shown as well as the most positive one out of the 3 Cockroaches.
The next door neighbor with anger management issues. He is an enemy of Oggy in many episodes. Every time Oggy destroys something that Bob owns he is almost always gets beaten/punched/kicked by Bob. However, on occasion, Bob will treat Oggy more like a friend. In "To Serve and Protect" Bob acts more friendly and even has respect to Oggy once he thinks that he'd make a good police officer. In "Steamed Out!" Bob actively wants to hang out with Oggy and Jack and tries to help them lose weight.
