Edit the existing image while keeping the person's two hands playing the synthesizer and the cat walking across the keys. Make the cat noticeably slimmer and more elegant: a lean, sleek, short-haired ordinary black domestic cat with a narrow silhouette and graceful posture, not fluffy or stocky. Keep realistic anatomy, natural warm daylight, lived-in organic music studio atmosphere, tactile synthesizer, and candid composition. No extra people, logos, text, or futuristic styling.
