A frizzy black cat wearing a blue and white striped long-sleeve shirt stands in front of a sink, holding an orange toothbrush and spraying a fan-shaped white foam to the left. Its long black fur is tousled, white whiskers are splayed out, and it gazes at the foam with its large light-colored eyes, sporting a comical expression. In front of a light blue background, the sink is equipped with a brass faucet, a light-colored basin, a small plate, and a transparent glass bottle. The image is in a hand-drawn watercolor style, with natural brush strokes and soft, fresh tones, presenting a humorous and adorable childlike atmosphere.
