Replace the cat in the reference video with the animal from the uploaded image.
Use the uploaded image only as the **animal identity and appearance reference**. Preserve its recognizable species, face, fur/skin pattern, colors, body shape, and other distinctive features.
Keep everything else in the original video unchanged, including:
* background and environment
* camera angle, framing, and camera movement
* lighting, shadows, and color tone
* video duration and speed
* all people, objects, and other animals
* timing and composition of the original scene
Make the uploaded animal **perform the same actions, movements, poses, and interactions as the original cat**, adapting the motion naturally to its anatomy. Match the original cat’s position and scale within the scene while keeping the replacement animal physically believable.
Maintain accurate tracking throughout the video, including turns, walking, jumping, sitting, body rotation, partial occlusion, and motion blur.
The final result should look as if the uploaded animal was naturally present and filmed in the original video. Avoid morphing, flickering, duplicate limbs, distorted anatomy, sudden identity changes, or remnants of the original cat.
