Use the provided image as the exact visual reference for the cat. Preserve the cat's appearance, proportions, fur pattern, pose, camera angle and side profile. The cat is running in place, creating the visual effect of running without moving forward. ONLY the two hind legs move. The front legs must remain fully extended forward throughout the entire animation. They are completely static and must not bend, lift, slide, retract, or change position in any way. The cat's hind legs perform a continuous alternating running cycle: one hind leg moves forward while the other moves backward, then they switch positions. The hind legs should move naturally and rhythmically, clearly creating a running-in-place motion. The cat's body remains essentially in the same horizontal position. The head, front legs, torso and tail remain stable, with only subtle natural body movement caused by the hind-leg running cycle. Do not make the cat move forward or backward. Fixed side-view camera. No camera movement, no zoom, no rotation. The cat stays centered in exactly the same position and scale throughout the shot. Solid bright chroma key green background (#00FF00), completely uniform and flat. No shadows, no floor, no reflections, no gradients, no background objects. Clean isolated animation suitable for chroma key compositing. Keep the entire cat visible inside the frame at all times. The animation should be smooth, seamless and physically coherent, with a clear repeating hind-leg running cycle.
