What is a pink cat? - briefly
A "pink cat" typically refers to a feline with a coat color that ranges from light pink to deep rose. This distinctive hue can be due to genetic factors or selective breeding practices aimed at creating cats with unique appearances.
What is a pink cat? - in detail
A pink cat, also known as a dilute tortoiseshell or a "dilute calico," is a feline with a distinctive coat color that results from a specific genetic mutation. The term "dilute" refers to a reduction in the intensity of the cat's base colors, typically black and red (orange), which are then modified by the dilution gene. This gene causes the black fur to appear gray or blue, while the red fur is lightened to pinkish-cream.
The genetic basis for this color variation involves the interaction between several genes. The primary genes involved include:
- Orange/Ginger Gene (O): Determines whether a cat can have orange fur. If a cat has at least one copy of this gene, it can express orange fur.
- Agouti Gene (A): Controls the distribution and pattern of colors on the cat's coat. This gene is responsible for creating the tortoiseshell or calico patterns.
- Dilution Gene (D): Reduces the intensity of black and orange fur, leading to a lighter, more diluted appearance. When this gene is present, black fur becomes gray or blue, and orange fur turns pinkish-cream.
The combination of these genes results in the unique pink cat coat. It's important to note that not all cats with the dilution gene will have a pinkish hue; the specific shade can vary depending on the interaction between different alleles (variants) of these genes.
Pink cats are often mistakenly thought to be albino, but this is not the case. Albinism is a separate condition that results in a lack of pigmentation, leading to white fur and red eyes. Pink cats, on the other hand, have a normal amount of pigmentation, just in lighter shades due to the dilution gene.
In addition to their unique coat color, pink cats are known for their striking appearance and can be highly sought after by cat enthusiasts and breeders. They are often found in mixed-breed or domestic short-haired cats but can also occur in pedigreed breeds such as the British Shorthair, Ragdoll, and Maine Coon.
Overall, a pink cat is not just an attractive pet; it's a fascinating example of genetic diversity in the feline world.
