The second mouse gets the cheese
There's very little I can add to this:
Courtship melodies, which are sung at a frequency beyond human hearing, are common among birds, insects, and frogs, but such behaviour in mammals had been thought to be restricted to humans, whales and bats.
The discovery that mice have a gift for song could mark the most significant leap in the understanding of rodents since it was discovered a few years ago that rats have a chirp-like laugh.
I see one parallel in my own life: were I to attempt a courtship melody, I'm sure she wouldn't give a rat's ass, as it were.
