Kitty White, commonly known as Kitty, is an anthropomorphic Japanese Bobtail cat portrayed as a human-like girl residing in the suburbs of London. Born on November 1st to parents George and Mary White, she shares her upbringing with her twin sister, Mimmy, under the care of grandparents Anthony and Margaret. Her pet cat, Charmmy Kitty, accompanies her daily life. Despite her feline appearance, she walks upright, engages socially as a peer, and is explicitly defined as a person rather than an animal.

Her iconic design includes a red bow perched on her left ear, paired with blue overalls over a yellow shirt. The deliberate lack of a visible mouth underscores her communication through expressive gestures and emotional resonance, reflecting themes of empathy and nonverbal connection. Her height and weight humorously equate to five and three apples, though these measurements adapt fluidly across different adaptations.

Kind-hearted and optimistic, she prioritizes responsibility and harmony, often mediating disputes or orchestrating community gatherings. Her interests span baking, curating miniature collectibles, and studying English, music, and art, with ambitions to excel as a pianist or poet.

Narratives oscillate between depicting her as a curious schoolgirl and a self-reliant adult managing a home or business, maintaining an ambiguous age. She navigates friendships, such as her bond with My Melody, blending youthful spontaneity with mature problem-solving during events like costume contests or holiday festivities. Central to her stories are family unity and communal cooperation, cementing her role as an enduring emblem of goodwill and positive relationships.
