There's a lot going on in this video.
1. The white kitty, named Milla, is clicking like the aliens from Signs.
2. The ominous black cat in the background that prefers to sit with one eye open is opening and closing its mouth in a somewhat chilling way. Must be some Vulcan mind trick Milla's pulling.
3. And come to think of it, what the hell are they looking at?! IS THERE SOMETHING BEHIND YOU?!
The truth is that Milla is deaf, which can explain her interesting noises. But let's be honest. If at the end of the video Milla looks into camera and says in a human voice, "DO AS I SAY, MEAT SUIT SLAVE," you'll cower before the screen and await instructions – right? Now, are you ready to check out Milla and friends?
