What are grey cats called? - briefly
Grey cats are commonly referred to as "blue cats" due to their distinctive diluted coat color. This term is widely used in cat breeding and feline genetics to describe cats with a grey or bluish-grey fur, regardless of their breed.
What are grey cats called? - in detail
Grey cats, often referred to as blue cats, are typically known for their distinctive coat color which is not truly grey or blue but rather a diluted version of black. This unique coloration is the result of a recessive gene that affects the production of melanin, the pigment responsible for coat color in cats. The term 'blue' is used to describe this particular shade of grey because it was once believed that the color resembled the sky on a clear day.
The gene responsible for the blue or dilute coat color is known as the dilution gene (d), which acts on both black and red pigments, creating shades of blue-grey and cream respectively. When this gene is present in a homozygous state (dd), it results in the characteristic blue or diluted coat color. It's important to note that not all grey cats are blue; some may have other genetic factors at play that influence their coat color.
In addition to the dilution gene, other genes can contribute to the appearance of a grey cat. For instance, the tabby pattern gene can create distinct stripes or spots on a blue coat, resulting in a blue-grey tabby. Similarly, the white spotting gene can produce striking patterns such as bicolor or tricolor coats with varying degrees of grey and white fur.
Some popular cat breeds known for their grey or blue coats include the Russian Blue, which is renowned for its short, dense blue-grey coat; the British Shorthair, often seen in a blue-grey coloration; and the Scottish Fold, which can also exhibit a beautiful blue-grey coat.
In summary, grey cats are commonly referred to as blue cats due to their unique diluted black coat color, which is influenced by specific genetic factors. Understanding these genetic nuances provides insight into the fascinating world of feline genetics and the diverse array of cat colors and patterns that exist.
