The Victorious Adventures of The Aristocats is the 19th crossover in the Victorious Adventures series. Its release date is unknown.
Tori, Trina, Cat, Robbie, Andre, Beck, and Jade all go to Paris where a mother cat named Duchess and her three kittens, Marie, Berlioz, and Toulouse, live in the mansion of retired opera singer Madame Adelaide Bonfamille, along with her English butler Edgar. Madame early on settles her will with her lawyer Georges Hautecourt, an aged, eccentric old friend of hers, stating that she wishes for her fortune to be left to her cats, who will retain it until their deaths, upon which her fortune will revert to Edgar. Edgar hears this from his own room through speaking tube and is unwilling to wait for the cats to die naturally before he inherits Madame Adelaide's fortune, and plots to remove the cats from a position of inheritance.
He sedates the cats and the HAC by putting sleeping pills into the cats' food and then heads out into the countryside to drown them in a creek. However he is attacked by two hound dogs, named Napoleon and Lafayette. Edgar escapes, leaving behind his umbrella, hat, the cats' bed-basket, and the sidecar of his motorcycle. The cats are unharmed, but stranded in the countryside, while Madame Adelaide, Roquefort the mouse, and Frou-Frou the horse discover their absence. In the morning, Duchess meets an alley cat named Thomas O'Malley, who offers to guide her and the kittens to Paris.
Marie, Berlioz, Toulouse and the HAC have a struggle returning to the city, briefly hitchhiking on the back of a milk cart before being chased off by the driver. Marie subsequently falls into a river and is saved by O'Malley. They then meet a pair of English geese, Amelia and Abigail Gabble, who are on a tour of France. The group head off, marching like geese, until they reach Paris and come across the girls' drunken Uncle Waldo. Abigail and Amelia then depart to take Waldo home.
Travelling across the rooftops of the city, the cats meet Scat Cat and his band, close friends to O'Malley, who perform the song Ev'rybody Wants to Be a Cat. After the band has departed and the kittens lie in bed, O'Malley and Duchess spend the evening on a nearby rooftop and talk, while the kittens listen at a windowsill. The subject of their conversation is the question of whether Duchess may stay and marry Thomas. Eventually, she turns him down, out of loyalty to Madame Adelaide. Edgar, meanwhile, retrieves his sidecar, umbrella, and hat from Napoleon and Layafette with some difficulty, knowing that it's the only evidence that could incriminate him.
The cats make it back to the mansion, whereupon O'Malley departs sadly. Edgar sees Duchess and Kittens coming and captures them, places them in a sack, and briefly hides them in an oven. The cats tell Roquefort to pursue O'Malley and get help. He does so, whereupon O'Malley races back to the mansion, ordering Roquefort to find Scat Cat and his gang. Roquefort tries to tell the allycats who sent him for help, but forgets O'Malley's name. At the last second, he angrily shouts, "Why did I ever listen to that O'Malley cat!" Edgar places the cats in a trunk which he plans to send to Timbuktu, Africa. O'Malley, Scat Cat and his gang, Frou-Frou, and the HAC all fight Edgar, while Roquefort frees Duchess and the kittens. In the end, Edgar is tipped into the trunk, locked inside, and sent to Timbuktu himself.
Madame Adelaide's will is rewritten to exclude Edgar and include O'Malley (after ironically claiming that the will would have included Edgar after all). She starts a charity foundation providing a home for all of Paris' stray cats. The grand opening thereof, to which most of the major characters come, features Scat Cat's band, who perform a reprise of Ev'rybody Wants to Be a Cat. Napoleon and Lafayette howel along, and Lafayette says, "Hey, Napoleon, that sounds like The End". Then Napoleon says, "Wait a minute, I'M the leader, I'll say when it's The End". Then the words The End hit him and he says, "It's The End".
- In the Victorious episode The Birthweek Song, Cat says she loves old people because "it's so cute how they shake when they pour their juice". But that isn't the only reason she likes Georges Hautecourt.
- During the introduction to O'Malley and Duchess, Tori sings Make It Shine.
