Uncle Dave Macon, in his recording "Grey Cat On the Tennessee Farm," has the lines:

The grey cat spit in the black cat's eye,
Little cat, little cat, don't you cry.

To the best of my memory (I'm not near my sources just now), in "Gonna Have 'Lasses in the Mornin' the Golden Melody Boys sing "the ?grey?black cat spit in the white cat's eye."

Both these recordings are old time country music 78s from the 1920s.
