I am a lame person. Here's what I did tonight. I bought a ringtone for my phone that sounds like a kitten meowing. I played it many times because it confused my cats a whole bunch. Squeak is currently sitting next to me, meowing because she can't figure where the kitten is, even though I stopped playing the ringtone like 15 minutes ago.
Squeak is the little tabby, and Nikki is the big fluffy one. My dog Elroy (the big gray butt) is also confused by the noise, but much less bothered than the cats.
