There was a 6.1 earthquake in Japan last month, and security video from inside a "kitty daycare" captured a bunch of the cats getting hyper aware and running 10 seconds before it hits. Like they knew something was up.
One theory is that the cats can sense the initial "p wave," which is shaking that people can't detect. There's also the chance they heard something that wasn't fully picked up by the camera's microphone.
