Reference sources indicate that tortoiseshell cats, which feature orange coat patterns, are almost exclusively female, while a female orange cat without white is considered a rare zoological curiosity.
tortoiseshell cats are almost exclusively female. Male tortoiseshells are rare and are usually sterile. Tortoiseshell markings appear in many different cat breeds
Tortoiseshell is a coat colouration in domestic cats named for its similarity to tortoiseshell pattern. Tortoiseshell cats, or torties for short, combine two colours other than white in an asymmetrical distribution, either closely mixed ('brindled') or in larger patches. The two colours always consist of one eumelanistic (black, blue, chocolate, lilac, cinnamon or fawn) and one phaeomelanistic (re
Male cats, like males of other therian mammals, are heterogametic (XY). The single X chromosome does not undergo X-inactivation, ergo coat colour is determined by which O-gene allele is present. Accordingly, the male cat's coat will be either entirely orange (O; XOY ) or melanistic black (o; XoY).
Leonard Doncaster was the first to prove sex linkage of the tortoiseshell coat colouration; i.e. that tortoiseshell is the female heterozygote of orange and black (XOXo) with the corresponding male being orange (XOY). In the course of his studies he discovered that the rare tortoiseshell male is often sterile.
Very rarely (approximately 1 in 3,000) a male tortoiseshell is born; these typically have an extra X chromosome (XXY), a condition known in humans as Klinefelter syndrome, and their cells undergo an X-inactivation process like in females. As in humans, these cats often…
Of these, the former is the one which bears the closest relationship to the wild cats of Africa and of Europe, the latter being an importation from the East. The striped (as distinct from the blotched) short-haired tabby is probably the one most nearly allied to the wild ancestors, the stripes being, however, to a great extent due to the European wild cat. In one direction the tabby shows a tendency to melanism which culminates in complete blackness, while in the other direction there is an equally marked tendency to albinism; grey cats, which may be regarded as tabbies whose stripes have disappeared, forming the connecting link between the tabby and the white cat. A mixture of the melanistic with the albinistic type will of course give rise to parti-coloured cats. A third colour-phase, the “erythristic” or red, is represented by the sandy cat, the female of which takes the form of the “tortoise-shell,” characterized, curiously enough, by the colour being a blend of black, white, and sandy. The so-called orange tabby is one phase of the erythristic type.
In the work of Palladius on agriculture, dating from about the year A.D. 350, reference is made to an animal called catus or cattus , as being useful in  ​ granaries for catching mice. This usage, coupled with the existence of a distinct term in Gaelic for the wild species, leaves little doubt that the word “cat” properly denotes only the domesticated species. This is confirmed by the employment in Byzantine Greek of the term κάττος or κάττα to designate domesticated cats brought from Egypt.
Blyth, which have recently been endorsed and amplified by R. I. Pocock ( Proc. Zool. Soc. London , 1907). According to these observations, two distinct types of so-called tabby cats are recognizable. In the one the pattern consists of narrow vertical stripes, and in the other of longitudinal or obliquely longitudinal stripes, which, on the sides of the body, tend to assume a spiral or sub-circular arrangement characteristic of the blotched tabby. This latter type appears to be the true “tabby”; since that word denotes a pattern like that of watered silk.
One or other of these types is to be found in cats of almost all breeds, whether Persian, short-haired or Manx; and there appear to be no intermediate stages between them. Cats of the striped type are no doubt descended from the European and North African wild cats; but the origin of cats exhibiting the blotched pattern appears to be unknown. As it was to a cat of the latter kind that Linnaeus gave the name of Felis catus , Pocock urges that this title is not available for the European wild cat, which he would call Felis sylvestris .
Examples may perhaps occasionally still be found in the uninhabited forests of Hungary and Transylvania, and occasionally in Spain and Greece, as well as in the Caucasus and in some of the Swiss cantons, but the original race has in most countries interbred with the domestic cat wherever the latter has penetrated.” In Great Britain wild cats survive only in some of the Scottish forests, and even there it is difficult to decide whether pure-bred specimens are extant.
Remains of the wild cat occur in English caverns; while from those of Ireland (where the wild species has apparently been unknown during the historic period) have been obtained jaws and teeth which it has been suggested are referable to the Egyptian rather than to the European wild cat. Such a determination is, however, extremely hazardous, even if it be admitted that the remains of cats from the rock-fissures of Gibraltar pertain to Felis ocreata .
Hares, rabbits, field-mice, water-rats, rats, squirrels, moles, game-birds, pigeons, and small birds, form the chief food of the wild cat. Apart from the above-mentioned division of the striped members of both groups into two types according to the pattern of their markings, the domesticated cats of western Europe are divided into a short-haired and a long-haired group. Of these, the former is the one which bears the closest relationship to the wild cats of Africa and of Europe, the latter being an importation from the East.
A third colour-phase, the “erythristic” or red, is represented by the sandy cat, the female of which takes the form of the “tortoise-shell,” characterized, curiously enough, by the colour being a blend of black, white, and sandy. The so-called orange tabby is one phase of the erythristic type. As to long-haired cats, there appear originally to have been two closely-allied strains, the Angora and the Persian, of which the former has been altogether replaced in western Europe by the latter.
That these long-haired cats have an ancestry, to some extent at any rate distinct from the ordinary short-haired breeds, is practically certain, and it has been suggested that they are derived from the “manul”
At the present day, however, Persians exhibit nearly all the colour and pattern types of the short-haired breeds, the “orange Persian” representing the erythristic phase. Turning to the tailless or so-called Manx cats, in which the tail should be represented merely by a tuft of hair without any remnant of bone, it seems that the strain is to be met with in many parts of Russia, and there is a very general opinion that it originally came from Japan or some other far eastern country. Throughout Japan, China, Siam, and the Malay countries, normal long-tailed cats are indeed seldom seen.
By far the most remarkable of all the Old World domesticated breeds is, however, the royal Siamese cat, which almost certainly has an origin quite distinct from that of the ordinary European breeds; this being rendered evident not only by the peculiar type of colouring, but likewise by the cry, which is quite unmistakable. Siamese cats may have the tail either straight or kinked, but whether the latter feature belongs of right to the breed, or has been acquired by crossing with the ordinary black and tabby kink-tailed cats of the country, is not known.

I n the estimation of persons who have no appreciation of the beautiful in animal life, a cat is a cat, and nothing but a cat. I have often observed some surprise expressed by visitors at a large cat-show on seeing an assemblage of so many different sorts of cats.
The he and she-cats are again divided in classes according to colour, as tortoiseshell and tortoiseshell and white, brown, blue or silver, and red tabby, tabby and white, and spotted tabby; also cats of unusual colour, and Manx, or tailless cats. A brief description of the characteristic points of the dif ​ ferent classes, as at the Crystal Palace, will be given in this chapter. The 13th of July, 1871, was a memorable day in the cat world, and an eventful one at the Crystal Palace, for it was then and there that the very first cat-show took place. Mr.
The varieties of our short-haired cat will now deserve our attention. Tortoiseshell .—Cats of this breed are  ​ also sometimes called Spanish cats, and display a very marked contrast to the tabby varieties. The general colour is a kind of reddish tawny, or sandy, more or less thickly covered with blotches or dabs of black. So very irregular are the markings in these cats, that some individuals are very handsome creatures, and some, on the other hand, are far from prepossessing in appearance. Tortoiseshell cats are of somewhat smaller growth.
The tail is barred with black, and a line of narrow stripes runs from the forehead, passes between the ears, and, passing down the neck, it disappears. The face is adorned with little swirls and stripes, so disposed as to give the general expression of the countenance that air of satisfaction so peculiar to puss. The under parts of the body may be of a paler colour, but no pure white is seen in a true tabby tom-cat. The tip of the nose, the lips, and the pads of the  ​ paws are to be desired of a dark colour. One, if not two, bold swirls of black across the chest are to be looked for in these cats.
They have been appropriately termed "the Lord Mayor’s chain." These tabby cats are generally large, portly animals, if properly reared, very intelligent, and often most affectionate. The females are most gentle, and the best of mothers. Blue or Silver Tabby .—This is a pale variety of tabby, which is sometimes beautiful. The ground-colour is a silver grey, with the stripes of a darker shade. Red Tabby .—In bold contrast with the blue, these fine cats are of a bright sandy yellow, with the usual markings of a deeper shade.
Some of these cats  ​ are of very good colour, so much so as to be distinguished by their proud owners under the very aspiring title of "Orange Tabby." These cats, in the main points, are like the brown tabby. The fur should be short, but full and thick, the ears rather short and round. In the tabby breeds the female is seldom without white, which generally appears upon the muzzle, throat, paws, etc. This is, most remarkably, a characteristic in the red tabby cats, a female of that colour without white being almost as rare a zoological curiosity as the wonderful tortoiseshell tom.
Spotted Tabby cats are distinguished from the others by having, instead of the usual stripes or cloudings, a pattern of quite a distinct type. The markings  ​ are broken up into small, well-defined spots, being more or less elongated upon the sides, transversely to the stripes along the back. In the class of spotted tabby he-cats at the Crystal Palace there might have been seen a specimen named "Coppa," which was justly awarded first prize. The owner of this cat, Mr. J. Scott, has kindly favoured me with the history of Coppa, which is of some interest when regarded zoologically.
Black .—These fine cats are not so  ​ commonly met with, of entire colour, as the brown tabbies, but are more plentiful than either the red or the blue. This colour is probably never met with in any of the wild cats, and would, I am inclined to think, be rare in the domestic races but for a prevailing superstitious notion, to be met with even in our enlightened age, that in some way good fortune or luck attends the homestead where a black cat dwells. And, moreover, that to destroy a black cat, or even a black kitten, from the purest motive, is an act likely to be followed by some misfortune.
The breed is curious, and it is doubtless on that account alone that it is preserved. In other respects these cats are like the ordinary animals. Siamese .—The handsome royal cat of Siam is at present but rare in this  ​ country, and is worthy of careful preservation as a breed. It is a curious cat, of one colour, a clear tawny or buff, with the exception of the muzzle, face, ears, and feet, which are black; and the fur is short, but thick and sleek. It is a cat of average size, and of compact build. At first glance it almost suggests to the mind the figure of a pug dog.
Gelded cats often grow very large, and, if properly kept, sometimes live to a great age. They make good, sociable pets, are not inclined to play truant, and they do not smell. The process is not a painful one if properly performed, and an animal thus treated will escape the temptation to stray or to combat with his fellows. At the age of six months, or even a little earlier, is the time at which a kitten should be sent to the veterinary surgeon. But on no account whatever must the operation be  ​ attempted upon an animal of more advanced growth.
