Fat Cat's Henchmen
Massive cleanup needed, sorry
Fat Cat is an established gang leader, and he employs other animals in his crime empire. He has a small inner circle of four henchmen, who serve as his bodyguards and perform direct criminal acts at his command. He also employs staff at his casino, at least occasionally, and will sometimes hire consultants for special jobs. Most of this contract work happens in comics and other continuities outside the main cartoon. When fans discuss "Fat Cat's henchmen," they usually mean the core gang of four.
Fat Cat's four major henchmen - they could be called his generals if they were smart enough to be given any real responsibility - are Mepps the cat, Wart the lizard, Mole the mole, and Snout the rat. Sometimes all four henchmen are on assignment, but often either Snout or Mepps are absent; it is unusual to see both of them in the same episode. Mepps appears in the bulk of the "mid-range" episodes, but Snout is not a late development or a replacement for him. As early as Adventures in Squirrelsitting, they are both present - in fact, they talk with each other in this episode.
