In Japanese tales, a familiar household cat may live long enough, grow large enough, or pass through such intense human feeling that it becomes a bakeneko: literally, a changed or transforming cat. The traditions are not one fixed biography. They are a family of stories in which the animal beside the hearth is understood to possess an inward life and, under certain conditions, powers that its household did not recognise.

Accounts give the bakeneko many possible signs. It may rise and walk like a person, speak with a human voice, wear human form, dance with a cloth or towel upon its head, or create uncanny lights. Some stories fear the cat's ability to imitate or replace a person; others centre on a wronged animal returning the cruelty it witnessed. These motifs vary by place and teller, and overlap with stories of the nekomata, though the two names are not interchangeable in every tradition.

One famous branch of Japan's supernatural cat tradition is the Nabeshima cat disturbance of Saga. In versions preserved through oral narrative, popular books and theatre, a cat takes up a human grievance after bloodshed in the Nabeshima household and enters the castle as an avenging presence. The details changed as the tale moved between local legend, kōdan storytelling and kabuki, but its emotional centre endured: loyalty, violence and memory survive in the creature that watched from the edge of the room.

Read with care, the bakeneko is more than a warning that an old cat might become monstrous. Its stories keep returning to the intimacy between people and animals, to what a household conceals, and to the possibility that a silent witness may understand far more than anyone believes. Familiarity is not the same as harmlessness, and companionship is never permission for cruelty.
