Extreme close-up of a rebellious punk rock cat, snarling with attitude. Shaggy paws.  Vibrant green mohawk standing tall, each spike meticulously detailed. Pierced ears adorned with multiple silver rings. Intense, mismatched eyes - one electric blue, one fiery amber. Whiskers adorned with tiny safety pins. Furry paws, furry toes. Worn leather collar studded with chrome spikes. Background hints at a graffiti-covered alley. Hyper-realistic fur texture, capturing individual strands and subtle color variations. Dramatic side lighting accentuates the mohawk and facial features.
