    I don't know about "cats eye" agates, but I have cut several white
    on white fortification agates from the Fourth of July Butte area of
    Arizona which display the shadow or venetian blind habit- that is,
    the bands are so fine that light actually gets trapped between them,
    resulting in a "play of darkness" rather than a play of color. The
    phenomenon is not common, and is usually seen in Lake Superior
    agates and some Mexican agates.
