The most commonly identified kind of tabby, the Classic (or ‘Blotched’) Tabby, tends to have a pattern of dark browns, ochres, and black. The uniform or nearly uniform striping around the circumference of the tail indicates feral origins in that particular cat’s family tree.[citation needed] Classic Tabbies have an ‘M’ pattern on the head similar to that of Mackrel Tabbies, but the body markings are different, having a whirled and swirled pattern with wider stripes that make what are referred to as “butterfly” patterns on their shoulders, and usually a bullseye or oyster pattern on the flank. The legs and tail are more heavily barred and the pattern is variable with respect to the width of the bands.
