Video of my kitten acting strange. Can anyone tell me whats she's doing?

So, the video will pretty much explain everything.
If someone can please explain to me why she's doing this, I'd pretty appreciate it. 

Thanks in advance!
 

Your cat hates that noise, simple as that. My cats freak out when I play my harmonica and do the same type of thing. That noise is hitch pitched, which seems to be what cats dislike about it. Heck, my cats even came running into my room just now to see what the noise on my computer was all about.

That noise sounds like a semi-pissed off cat.  Sugar went after the speaker and it is on a shelf 6 feet off the floor. 

She's weirded out cause it sounds like a kitten.

In the wild, adult cats actively avoid other cats' kittens most of the time. They know if they go near the kittens, their mama is likely to come around and give the adult a butt whoopin. :lol3: Sort of like avoiding bear cubs.

So she's just worried there's a kitten around, is all.

Oh, right.  A kitten is what it sounds like.  S&S were several months old when I got them, so I had forgotten what a kitten sounds like.
