Create a realistic image of a male American Shorthair cat with short, sleek fur in a warm brown color. The cat should have large, round green eyes with a gentle yet playful expression. His fur should have soft, subtle tabby stripes running along his body, especially on his back and tail. He has a well-built, muscular frame but appears relaxed. Capture the cat in a natural pose, such as sitting or lying down, with his ears perked up, as if he is curiously observing something in the distance. The overall image should convey a sense of calmness and contentment. --ar 9:16  --s 1000
