I'm not so sure about this. I think Stinky the Cat responds to anything that sounds like a can opener. Or food klinking in her dish. Or the sound of the refrigerator opening up. Do any of those make an 'eeek' sound? Maybe in a super-sub-sonic sense, like a dog-whistle. But I think more research is in order here, before I put any socks in my basket on this whole idea.
