Ok, here's what I was thinking.
The rooster the duke sent to fight chanticleer makes his return to the dukes lair. he convinces the duke to male the kitty (Edmond) suffer. The duke turns Edmond back into a kitten and turns Edmond's family into mice and eats them, as he goes to Eat Edmond, Patou bites him on the leg, and Edmond turns his flashlight on the duke.
