Cats normally seems so neat and self-contained, especially next to sloppy-mouthed dogs who are always rolling in crap and then shaking said crap off onto your dinner plate. But it turns out, cat faces are basically a cleverly-arranged façade of loose skin and mucus. That sounds very gross, but this video is only a little gross. It's mostly a cool look at our domestic kitty friends that gives you plenty of opportunities to think about how weird it must be to have two sets of eyelids.
