Create a scene of two cats, a brown male cat with short fur and subtle tabby stripes, and a pure white female cat with sleek, spotless fur, relaxing together in an outdoor Japanese hot spring. The hot spring should be surrounded by smooth rocks and lush greenery, with steam rising from the warm water. The brown male cat is playfully splashing the water, while the white female cat is peacefully soaking, enjoying the tranquility of the moment. The atmosphere should feel calm and serene, with soft steam and warm lighting adding to the relaxing mood of the scene. --ar 1:1  --s 1000 --sref <https://s.mj.run/5TI4JH7WqAM>
