I'm sure this study about rat laughter is widely known here. Has anyone tried using a bat detector like this one to hear it? At 50 khz, rat laughs fall almost squarely in the center range of this detector device, so I figure it should work right?

Funny, I was just watching videos about this yesterday. I really would like to try this someday, can't justify the expense at the moment. Would be really cool to hear my rats' "voices" though.
