Sora Prompt: Create a short, realistic video based on this image: a close-up of a calico cat lying flat on the floor with a relaxed expression. Behind the cat, a pair of human legs in white tights and black shoes are playfully kicking in the air. Animate the scene so the cat gently kicks its back legs in a playful, “bicycling” motion for a few seconds, then slowly stands up, stretches, and walks away from the camera. Keep the perspective, lighting, and background consistent with the original image.
