The subject passed in front of the camera and apparently peered around the corner where the cats are fed, either looking for cat food or a cat, then turned and went back the way it came.
The color of the body fur appears white in the video, but it may be a light brown or tan highlighted by the moon light. I will attempt to do some follow up testing to determine what colors look like in the green night vision. Also will do some follow up photos to determine the size. But I get the impression that it is not very large.
