Oggy and the Cockroaches (1999) : 3x34

Oggy finds another cat that is a near-perfect replica of himself (save for a white spot on his tail). When Jack learns of this, he decides to play a cruel joke on the cockroaches making them think that Oggy is everywhere, resulting in double the trouble, double the laughs.(There's a deleted scene in this episode. When Joey finds out that Oggy follows him in space, there's a part that his head exploded. But since it was deleted due to censorship, the result is the scene when he cries.)
