Is it hard to fake this video? (Score 0)

There is a video on the right of this news story and they shut the lights on and off. Looks pretty real to me, but then again I don't know much about video. At least it isn't just a photoshop picture, but that doesn't mean these cats where injected with some sort of luminescent dye.
