In the quiet and seemingly boring town of Bootsville, the life of an ordinary boy named Coop Burtonburger changes forever when his sister adopts a small, hairless "cat" with a hostile gaze and strange behavior. This cat, whom she names Mr. Kat, is no ordinary pet: She is an alien from an advanced race called Kat Nebulon, secretly sent to Earth for missions that Coop can't figure out… but he knows they're never good.

From day one, Coop notices that Mr. Kat possesses alien technology, superhuman strength, and near-military intelligence. Although he tries to tell his family and neighbors, no one believes him: to everyone else, Coop is an over-the-top, troublesome kid, while Mr. Kat is "a harmless little kitty."

Thus begins a silent war: Coop vs Kat, a battle of wits, traps, sabotage and everyday survival.

Each episode is a clash: Kat tries to complete a mission (repair her communicator, contact her home planet, destroy threats, obtain resources), while Coop does everything he can to stop her and prove the truth. This leads to constant destruction, chaos, and absurd situations… but in the end, Coop always ends up being blamed.

Throughout the story, Kat reveals more about her race: a civilization that worships and controls domestic cats as spies across the universe. Their goal: to conquer worlds using felines as covert agents.

Coop, though a child, becomes the only human who understands the true threat. The city becomes a secret battleground. Nobody knows that the fate of Earth depends on a 10-year-old boy and his eternal fight with a vengeful alien cat.
