Among the Republic starships destroyed by Admiral Trench -- according to intelligence reports displayed on Admiral Yularen's screen -- are the cruiser The Righteous and the frigate Swift Return.

Cut from the episode but present in the script was the name of the Jedi Master in charge of the Republic task-force at the Battle of Malastare Narrows: Jedi Kep-She.

Chronologically, this episode precedes all the others that have been broadcast thus far. "Cat and Mouse" is followed by Season One's "The Hidden Enemy" and then an episode originally titled "The New Padawan" that was re-edited into The Clone Wars feature film.

Early in production, Admiral Trench's name was rendered as "Admiral Taranch," a more obvious nod to his tarantula inspiration. Though his name was changed, Yularen's intelligence report shows the original spelling in Aurebesh.
