The Blue Cat of Castle Town

The Blue Cat of Castle Town, by Catherine Cate Coblentz, 1949. The story of the titular blue cat begins when he is just a little blue kitten, born under blue moon long ago in a meadow by a river in Vermont. His anxious mother knows that blue kittens can hear the song of the river, and follow that song to strange fates. But despite her efforts, the kitten hears. The song praises the power of the individual to create beauty--"all that is doing, do well"-- and the river sends blue kitten on a quest to Castle Town, to sing that song to the people there who might have ears to hear. There is one man in Castle Town, though, that the river warns blue kitten against--Arunah Hyde, whose own song is all about moving quickly through the world racking up more and more money and power.
