Cataracts Lyrics

Lyric discussion by neilschmeil 

Cover art for Cataracts lyrics by Andrew Bird

There's some interesting stuff going on in the main verse:

When our mouths are filled with uninvited tongues of others- this suggests a kind of intrusion, possibly an intrusion of ideas like discussed by others above

And the strays are pining for their unrequited mothers- intro to the image of cats who, in a kind of antithesis to the above statement, are seeking some kind of connection or "intrusion"- they are inviting

Milk that sours is promptly spat- we all know that cats are intimately connected with milk

Light will fill our eyes like cats- perhaps the most interesting line since cats, unlike humans, see better in the dark and more clearly in the light

Cataracts- thus the blurriness of a cataract is explained by the difficulty a cat has seeing when its eyes are "filled with light"

this makes for an interesting simile between cat's vision and human vision- perhaps he is suggesting the more we know, the less we know?
