Modified to have garter stitch edges (instead of stockinette) from http://stitch-maps.com/patterns/display/cats-eye-1/.
Original pattern presumably from Barbara Walker's "A Treasury of Knitting Patterns," Page: 178.
See http://thewalkertreasury.wordpress.com/?s=cat for a picture of the original pattern.
4 Horizontal repeats (26 stitches) is a good size for a dishcloth, beginning and ending with 6 rows of garter stitch.
Shown with a cast-on count of 18 stitches.
