The show centers on Oggy, a content and lazy, albeit very tender fat blue cat, who would usually spend his days watching TV and cooking - if it wasn't for the three roaches in the household: Joey, Dee Dee and Marky (named after members of the punk group Ramones). The trio seems to enjoy generally making Oggy's life miserable, which involves mischief ranging from (in most cases) plundering his fridge to such awkward things like hijacking the train Oggy just boarded. Oggy usually finds creatures accompanying him to the end of the episode, such as crabs, clams, a horse, a very technologically advanced child, a puppy, and an octopus. However, it's not always Oggy who wins.
