Leo's cat, Monsieur Whiskers, isn't your ordinary house pet. He's clever, charming, and just a little too curious for his own good.
So when he spots an open train door one sunny morning at the London station, curiosity takes over — and poof! he's off on the adventure of nine lifetimes... all the way to Paris!

What follows is a whirlwind of funny, heartwarming chaos as Monsieur Whiskers wanders through the City of Lights, making new friends in the most unexpected places:

Pierre, a tiny Parisian mouse with a giant love for cheese and adventure.

Bella, a dramatic pigeon who dreams of being a famous singer.

Conductor Marcel, who keeps trying (and failing) to catch the runaway cat with a train ticket.

Chef Gaston, a baker who mistakes Whiskers for his new kitchen assistant—leading to one very fluffy croissant disaster!

As Whiskers charms everyone he meets, he becomes an overnight celebrity — Le Chat du Croissant! — the most famous feline in France. Meanwhile, Leo sets off on a frantic journey to find his beloved cat, guided by clues, kindness, and a little bit of luck.

When boy and cat finally reunite beneath the twinkling lights of the Eiffel Tower, they both learn something magical:
Adventure can take you far, but love always leads you home.
