That strange sound

You know how in the first episode the scientists are playing a sound loop of the alien sound and all the rats in the lab go hyper.

Well, I was watching that scene and suddenly realized that my cat had sat down right in front of the tv set and was watching the screen with complete attention. When the sound stopped, he went back to being a cat.

But maybe the show really was about alien invasion. It just didn't last long enough to succeed.
