According to the EXIF data on this photo, it was taken on Wednesday at 4:44 PM. What you're seeing is the Dinner Stare™, designed to make it clear that the cats will brook no tardiness in producing dinner promptly at 5:00. They are not amused that instead of making preparations, I'm sitting on my butt watching some stupid TV show.
Needless to say, dinner was produced on time. By 5:02 it was gone. The Late Night Snack Stare™ commenced at about 8:30.
