Cats with blue, cream, and white fur are known as muted calicoes. It’s more of a colour pattern than a breed. Multi-coloring, piebalding, and colour dilution genes are present in these cats, sometimes known as diluted calicoes. Almost all of them are female. Male muted calicoes are very uncommon, and they are nearly always infertile.
What Makes A Calico?
On their X chromosomes, cats have genes for orange or black coats. Female cats have two X chromosomes by definition, and they may contain genes for both orange and black hair. One of the genes gets inactivated at random (a process known as lyonization), resulting in patches of any fur colour. Tortoiseshells are cats with orange and black hair.
Cats also have distinct genes for white fur that is not coloured. Piebalding is a condition in which male and female cats have patches of white fur. Calicoes are tortoises with piebalding on their shells.
What Are The Characteristics Of A Muted Calico?
Colour dilution genes are also found in cats. When one of these variations occurs, an orange coat becomes cream and a black coat turns grey, which cat lovers refer to as “blue.”
Other colour-mitigating genes may be found at other loci, such as those that cause black to become chocolate or red, but cream-blue dilation is the one to be concerned about. Clumping and uneven pigment dispersion are caused by this recessive feature, resulting in lighter fur colour.
Muted calicoes are calicoes with cream-blue dilutions.
Breeds And Variations
Muted calicoes are not a widespread breed, although they do share a common colouration.
Although many of these cats are domestic shorthairs, or “mutts,” they do not have a monopoly on cream, blue, or white fur. Calico coats may be seen on Manx and Persian cats, for example.
While the majority of tri-colour cats are calicoes, others, such as the tri-colour Bengal, aren’t. Muted calicoes, on the other hand, are all calicoes. Muted calicoes have no standard size or temperament due to the broad variety of breeds that may be used.
Male Muted Calicos
Because male cats only have one X chromosome, they can’t have both the orange and black hair required for calicoes or the cream and blue fur required for muted calicoes.
Klinefelter syndrome is a disease in which male cats get an additional X chromosome, resulting in a wide range of colour variants, including calico and muted calico colouration. Unless the male cats have another genetic abnormality, which is more uncommon, the disease makes them infertile.
