The show centers on Oggy, a content, lazy, fat blue cat, who would prefer to spend his days watching television and eating - if not 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 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.
The cartoon itself relies on slapstick humour, much like its inspirer, Tom and Jerry, only amplifying the level of extremities up a notch. While traditional slapstick cartoon characters prefer dropping anvils and pianos on each other, this show sometimes uses even buses or submarines. Despite these however, most gags are easily accessible and enjoyable for younger viewers. Since dialogue is kept to a minimum the humour is entirely visual.
