The video shows a large mountain lion walking around a living room. The room has a wooden floor and is furnished with a television, a stereo, and a blue bucket. The mountain lion appears to be looking around and sniffing the air. At one point, the lion approaches a toy on the floor and seems to be interested in it. The lion's fur is a light brown color, and it has a long tail. The room is well-lit, and there are no other animals or people visible in the video.
