He and his men got carried away by a train with Lena Hyena on board
"Jolly good. Now pay attention. Cats and gentle mice, lend me your ears. It is my distinguished pleasure to invite all of you to share our dinner--Triumph! To share our triumph! Today, we herald in a momentous new feast..ival. Feastival...festival. To mark this brilliant and illustrious snack occasion, I will, with these golden scissors, hereby cut...a red...ribbon."
Cat R. Waul is the leader of the Cactus Cat Gang and Fievel Mousekewitz's arch-nemesis. In Mrs. Brisby Meets Fievel, he schemed to open his new casino in Toontown, keep Fievel, Cholena, Tanya, Yasha, and Mrs. Brisby alive and turn his family into mouse burgers.
In Hidden Chronicles Cat R. Waul appeared as one of the major antagonists who plotted to capture Pooh and Tigger and sell them to the scientists of NIMH.
Cat R. Waul shares similarities with Gaston from Beauty and the Beast, Turbo/King Candy from Wreck-It Ralph, and Lord Victor Quartermaine from Wallace and Gromit: The Curse of the Were-Rabbit as they believe themselves to be heroes, and intend to kill their "ugly", "monstrous", "abusive", "cruel", "hateful", and "nasty" foes (the Beast, Wreck-It Ralph, the Were-Rabbit, Mama and Papa Mousekewitz). Although the other villains failed, Cat R. Waul succeeded killing the child hero's innocent parental figures whom he considered cruel, hateful, and abusive parents (Mama and Papa Mousekewitz).
Cat R. Waul is similar to Scar from The Lion King and Tabitha Harperstein from Andrew in New York. They killed a child hero's parents. (Scar killed Mufasa in the wilderbeest stampede, Tabitha Harperstein killed James and Rachel by poisoning their free lunch on Coney Island for tattling on her, Cat R. Waul killed Papa and Mama Mousekewitz with a giant mousetrap).
