A tabby is any domestic cat that has a coat featuring distinctive stripes, dots, lines or swirling patterns, usually together with a mark resembling an M on its forehead. Tabbies are sometimes erroneously assumed to be a cat breed. In fact, the tabby pattern is found in many breeds, as well as among the general mixed-breed population. The tabby pattern is a naturally occurring feature that may be related to the coloration of the domestic cat's direct ancestor, the African Wildcat, which (along with the European Wildcat and Asiatic Wildcat) has a similar coloration.
All those patterns have been observed in random-bred populations. Several additional patterns are found in specific breeds. A modified Classic tabby is found in the Sokoke breed. Some are due to the interaction of wild and domestic genes. Rosetted and marbled patterns are found in the Bengal breed.
The Mackerel tabby pattern has vertical, gently curving stripes on the side of the body. The stripes are narrow and may be continuous or broken into bars and spots on the flanks and stomach. An "M" shape appears on the forehead along with dark lines across the cat's cheeks to the corners of its eyes. Mackerels are also called 'Fishbone tabbies' probably because they are named after the mackerel fish. Mackerel is the most common tabby pattern. The legs and tail have dark bars as do the cat's cheeks.
The Classic (also known as "Blotched" or "Marbled") tabby tends to have a pattern of dark browns, ochres and black but also occurs in grey. Classic tabbies have the "M" pattern on their foreheads but the body markings have a whirled or swirled pattern (often called a "bullseye") on the cat's sides. There is also a light colored "butterfly" pattern on the shoulders and three thin stripes (the center stripe is dark) running along its spine. Like the Mackerel tabby, Classic tabbies have dark bars on the legs, tail, and cheeks.
The Ticked tabby pattern produces agouti hairs, hairs with distinct bands of color on them, breaking up the tabby patterning into a salt-and-pepper appearance. Residual ghost striping or "barring" can often be seen on the lower legs, face and belly and sometimes at the tail tip.
The Spotted tabby is a modifier that breaks up the Mackerel tabby pattern so that the stripes appear as spots. Similarly, the stripes of the Classic tabby pattern may be broken into larger spots. Both large spot and small spot patterns can be seen in the Australian Mist, Bengal, Egyptian Mau, Maine Coon, and Ocicat breeds.
The tabby patterns are due to three distinct gene loci and one modifier:
The agouti gene, A/a, controls whether or not the tabby pattern is expressed. The dominant A expresses the underlying tabby pattern, while the recessive non-agouti or "hypermelanistic" allele, a, does not. Solid-color (black or blue) cats have the aa combination, hiding the tabby pattern, although sometimes a suggestion of the underlying pattern can be seen (called "ghost striping"). However, the O gene for orange color suppresses the aa genotype, so there is no such thing as a solid orange cat.
The primary tabby pattern gene, Mc/mc, sets the basic pattern of stripes that underlies the coat. Mc is the wild-type tabby gene and produces what is called a Mackerel striped tabby. Classic tabbies are cats who also possess mc, a recessive mutant gene that produces the blotched pattern.
The Ticked tabby pattern is on a different gene locus than the Mackerel and Classic tabby patterns and is epistatic to the other patterns. A dominant mutation, Ta / ta, masks any other tabby pattern, producing a non-patterned, or Agouti tabby, with virtually no stripes or bars. If the Ticked tabby pattern gene is present, any other tabby pattern is masked. Cats homozygous for the ticked allele (Ta / Ta) have less barring than cats heterozygous for the ticked allele. When a cat of this genetic make up is selectively bred for lack of barring and wide banding on the hair shaft the resulting pattern is referred to as shaded.
The English term "tabby" comes from the 1630s, "striped silk taffeta," from the French "tabis," meaning "a rich, watered silk (originally striped)," from Middle French atabis (14c.), from Arabic attabiya, from Attabiy, a neighborhood of Baghdad where such cloth was first made, named for Prince 'Attab of the Umayyad Caliphate. Compare to Spanish "ataviar", meaning to decorate or to dress or wear (often implying very elegant and/or expensive clothing). The term tabby cat, "one with a striped coat", is attested from the 1690s; the shortened form tabby was first attested in 1774. The idea of "female cat" (1826) may be influenced by the feminine proper name Tabby, a pet form of Tabitha, which was used in the late 18th century as slang for a "difficult old woman."
Since the tabby pattern is a common wild type, it might be assumed that medieval cats were tabbies. However, one writer believed this to be untrue, at least in England. Some time after the mid-17th century, the natural philosopher John Aubrey noted that William Laud, the Archbishop of Canterbury was "a great lover of Catts [sic]" and "was presented with some Cyprus-catts, i.e. our Tabby-catts". He then claimed that "I doe well remember that the common English Catt, was white with some blewish piednesse (i.e. white with grey parts) : sc, a gallipot blew. The race or breed of them are now almost lost."
