I've seen that last one before, with the captions. That poor kitty, he
looks kind of scared. It sounds like the noises he's making are meant
to scare off whoever/whatever is making him nervous.

And the one where the guy asks, "Do you love me?" Remember a while
ago someone posted a video of a cat making weird noises and weird
faces, and everyone thought something was wrong with the cat? Then
someone finally noticed there was a hand near the cat's rear end,
scratching it at the base of its tail? This cat is getting very
similar attentions, and it's also making weird faces and sounds. So
maybe some cats do that when scratched right at the base of their
tail.

I did love the first one, though. "Hello?" "Hello!" I swear, that
cat really was trying to imitate a person saying Hello! (Doing a
pretty good job of it, too.)
