Black cats are unique among felines in that they can have blue skin. This is a result of a genetic mutation that causes the black pigment in their fur to be expressed in their skin as well. While this may seem like a cosmetic oddity, it can actually be indicative of health problems.

Blue skin is more susceptible to sun damage and can develop cancerous growths more easily than other colors of cat skin. If you have a black cat with blue skin, it’s important to monitor their health closely and consult with your veterinarian if you notice any changes.

You may have heard that black cats have blue skin. But is this true? The answer is a little complicated.

First, it’s important to understand that the term “black cat” can mean different things. Sometimes it refers to a cat with black fur, and other times it refers to a cat with dark-colored fur of any color. So, when people say that black cats have blue skin, they may be referring to either type of black cat.

As for the blue skin itself, it’s actually not really blue. It’s more of a grayish-blue color. And it’s only visible in certain areas, such as the ears, nose, and paw pads.

The reason why these areas appear blue is because they don’t have much pigment (color). So when light hits them, they reflect back a bluish color. So, do all black cats have blue skin?

No, not all of them. But many do!

Blue Spot on Cat Skin

If you have a cat, you may have noticed at some point that they have a small blue spot on their skin. This is actually quite normal and nothing to worry about! The blue spot is called the third eyelid, or nictitating membrane.

It’s a thin piece of tissue that covers the inner corner of the eye and helps keep it moist and protected. Cats can sometimes get debris or irritants in their eye, and the third eyelid will help flush it out. If your cat’s third eyelid is showing more often than usual, it could be a sign of an underlying health condition and you should take them to the vet for a check-up.

Why is My Black Cats Skin Blue?

Your black cat’s skin may look blue because of a genetic condition called methemoglobinemia. This disorder causes an abnormal amount of methemoglobin, a form of hemoglobin, to build up in the blood. Methemoglobin cannot carry oxygen as efficiently as regular hemoglobin, so affected cats may have difficulty breathing and may be lethargic.

If your black cat’s skin looks blue and she is having trouble breathing, contact your veterinarian immediately.

Can Cats Have Blue Skin?

No, cats cannot have blue skin. While some animals like reptiles and amphibians can have blue skin due to the presence of a pigment called biliverdin, this pigment is not present in mammals. Biliverdin is actually a by-product of the breakdown of hemoglobin, so it is possible for an animal to have blue skin if they have a condition that causes their hemoglobin to break down at an accelerated rate.

However, since cats do not have this condition, their skin will always be some shade of pink or brown.

Does a Black Cat Have Black Skin?

Yes, a black cat has black skin. The melanin in their skin gives them their unique coloration.

Are Black Cats Blue?

No, black cats are not blue. While the colors black and blue are often associated with one another, they are two completely different colors. Black is produced by the absorption of all light, while blue is created by the reflection of short-wavelength light.

So, while a black cat may appear to have a blue hue in certain lighting conditions, this is simply an optical illusion.



No, black cats do not have blue skin. However, their fur may appear to be blue when viewed in certain lighting conditions. This is due to the way light reflects off of the cat’s fur.

Black cats are also sometimes said to have green eyes.
