In the video, a large mountain lion is seen lying down on a rug in a living room. The room has a wooden floor and a large window that lets in natural light. The mountain lion is brown with a white chest and appears to be relaxed and comfortable in its surroundings. The camera pans around the room, giving a full view of the space. The mountain lion eventually sits up and looks directly at the camera, revealing its sharp teeth and piercing eyes. The room is otherwise empty, with no other animals or people visible.
