In the video, a large mountain lion is seen walking through a room with wooden floors. The room is well-lit and has a wooden door with glass panels. The mountain lion has a brown coat and appears to be calmly walking around the room, occasionally looking towards the camera. There are no other animals or people visible in the video. The mountain lion's movements are slow and deliberate, and it seems to be exploring the room. The video does not contain any dialogue or sound effects.
