ultra-realistic, Draw a cat giving a thumbs up with a positive attitude. The cat is standing on its hind legs, smiling broadly at the camera, and holding up a thumb with one of its front paws. Keep the background simple to enhance the cat's positive vibe. Emphasize the cat's approachable and overflowing positive energy through its expression and posture. <https://s.mj.run/8Rs5DjmPKfI>
