   you (original poster, I don't have the first post anymore) might also 
consider other animals - small rodents, cats. Cats hear up to about 
60kHz (that's what I remember, even if it's not the right number they 
hear a lot higher frequencies than we do), it was explained in the book 
I read that that's what they need to be able to hear the small rodents 
(so I guess small rodents emit sounds up to about 60kHz), plus cats use 
higher frequencies to communicate among themselves (that's why you only 
hear them doing the meow sounds when they are around humans).
