From Pink to Pale. What Your Cat’s Gum Color Says About Their Health


Cat owners often overlook their feline friend’s gums, but paying attention to gum color can provide important clues about a cat’s health. Gum color results from blood circulation and oxygenation. When a cat is unwell, changes in gum color may signal an underlying illness or condition.

This article will provide an overview of normal gum color in cats, as well as changes in gum color that can indicate disease. We will cover conditions associated with pale gums, bright red gums, blue/purple gums, yellow gums, white gums, and spotted gums. Recognizing abnormal gum colors and understanding what they signify can help cat owners determine when to seek veterinary care.

Normal Gum Color

The gums of healthy cats should be a light pink color. According to Vetwest Veterinary Clinics, normal healthy cat gums will be a “soft pinkish color.”[1] Pet Wellbeing explains that ideal healthy cat gums are a light pink that is “neither too bright nor too pale.” They note that some variation in gum color between cats is normal.

A nice bubblegum or salmon pink shade is generally considered normal and healthy for cat gums. Very pale pink or white gums can be a sign of illness, while extremely bright red gums may indicate fever or inflammation.

It’s important for cat owners to be familiar with their pet’s usual gum color when they are healthy. That makes it easier to notice any abnormal changes that could signal illness or disease.


Pale Gums

Pale gums occur when a cat’s gums lose their normal pink color and become white or pale pink instead. This is often a sign of an underlying health issue. Some of the most common causes of pale gums in cats include:

Anemia – Anemia refers to a low red blood cell count. It can be caused by blood loss, destruction of red blood cells, or lack of production of new red blood cells. Cats with anemia will often have very pale or white gums due to the reduced number of red blood cells carrying oxygen through the body (Source).

Blood loss – Significant blood loss, such as from trauma or internal bleeding, can cause pale gums. As the cat loses blood, there are fewer red blood cells circulating to carry oxygen and give the gums their normal pink color.

Shock – Shock occurs when blood pressure drops dangerously low. This restricts blood flow and oxygen delivery throughout the body, including to the gums, causing them to turn pale or white. Shock can be caused by blood loss, dehydration, infection, or other system failures (Source).

If your cat’s gums appear pale or white, it is important to have them evaluated by a veterinarian as soon as possible, as this likely signals a serious underlying health problem requiring prompt treatment.

Bright Red Gums

One common cause of bright red inflamed gums in cats is gingivitis. Gingivitis is an inflammation of the gums caused by a buildup of plaque and tartar along the gumline. The gums become swollen, reddened, and can bleed easily. If left untreated, gingivitis can lead to more serious dental disease and tooth loss.

Plaque contains bacteria that irritate the gums. As plaque accumulates, it hardens into tartar that sticks to a cat’s teeth. Tartar above and below the gumline causes irritation and inflammation. The bacteria in plaque also release toxins that cause more swelling. All this leads to the classic symptoms of gingivitis – red, puffy, bleeding gums.

Gingivitis can occur in any cat, but is more common in older cats as their teeth accumulate more tartar. The inflammation is often worst along the back teeth where plaque and tartar readily build up. Cats with suppressed immune systems may also be more prone to gingivitis.

Treatment involves a thorough dental cleaning by a veterinarian to remove all plaque and tartar from the teeth and below the gumline. Antibiotics and anti-inflammatory medication may also be prescribed. Following up with regular tooth brushing and dental care can prevent gingivitis from recurring.

Left untreated, gingivitis can progress to advanced gum disease called stomatitis where there is severe inflammation and redness of the gums as well as tooth loss. Stomatitis is very painful and makes it difficult for a cat to eat normally. That’s why it’s important to see the vet promptly if your cat has signs of any gum inflammation.

Blue/Purple Gums

Blue or purple gums in cats, also known as cyanosis, indicates a lack of oxygen in the blood or exposure to toxins. Cyanosis occurs when there is an issue with the cat’s respiratory or circulatory system that prevents proper oxygenation of the blood and tissues.

Some potential causes of cyanosis include:

  • Heart disease or heart failure, which reduces blood circulation
  • Lung disease, which prevents proper oxygen absorption
  • Smoke inhalation
  • Anemia, from blood loss or red blood cell damage
  • Toxins like anti-freeze that affect oxygen carrying capacity

Cyanosis is a serious condition requiring emergency veterinary treatment. Prolonged oxygen deprivation can lead to organ damage, collapse, coma or death. Quick action is needed to determine the underlying cause and restore normal oxygen levels. Treatment may include oxygen therapy, blood transfusions, medication, or surgery.

Yellow Gums

Yellow gums in cats can be a sign of jaundice or icterus, which refers to a buildup of bilirubin in the blood. Bilirubin is a yellow pigment produced when red blood cells break down. Healthy cats can process and remove bilirubin from the body, but liver disease or blood disorders can cause an excessive accumulation of bilirubin. This results in yellow discoloration of the gums and other tissues like the ears and footpads (1).

Some common causes of yellow gums in cats include (2):

  • Liver disease – Such as hepatitis, cirrhosis, or liver cancer
  • Gallbladder problems – Gallstones or inflammation
  • Pancreatitis
  • Hemolytic anemia – When red blood cells are destroyed prematurely
  • Blood parasites

Yellow gum color indicates there is a serious underlying health problem. It’s important to take cats with yellow gums to the vet promptly for diagnosis and treatment. Left untreated, many of the conditions that cause yellow gums can be fatal. With aggressive therapy, the outlook depends on the underlying cause. Liver disease like hepatitis may be reversible if caught early, while liver cancer has a poorer prognosis (1).

White Gums

Severely pale gums that appear white often indicate an underlying medical issue such as anemia or circulatory shock. Anemia refers to a lack of healthy red blood cells, which carry oxygen throughout the body. When a cat has anemia, its gums will become very pale or white as oxygen levels drop. Circulatory shock similarly involves decreased blood flow and oxygen, causing the gums to turn white as blood pools away from peripheral areas like the gums.

Potential causes of anemia leading to white gums include blood loss, bone marrow disease, and the destruction of red blood cells. Circulatory shock can arise from severe dehydration, heart failure, or septicemia. In either case, white gums signify a depleted supply of oxygenated blood and require prompt veterinary care. Immediate treatment such as blood transfusions, intravenous fluids, and medication may be necessary to stabilize the cat.

Cat owners noticing white gums should take the cat to the vet right away, as this color indicates a dire medical condition. With rapid treatment, many cats can recover fully from the underlying issue causing the color change. But white gums signify an oxygen-deprived body and a dire need for urgent veterinary care.

Spotted Gums

Sometimes a cat’s gums can develop dark spots or mottled patches. This is often caused by a condition called lentigo, which causes black spots on the gums, lips, nose and around the eyes of cats with light fur colors like orange, silver or white. Lentigo is benign and not a cause for concern, but spotted gums can also indicate more serious medical issues.

Spotting or mottling on the gums can be a sign of anemia, which means the blood has a reduced number of red blood cells. Anemia prevents sufficient oxygen from reaching tissues and causes the gums to appear pale, grayish or spotted as blood flow is impaired. Causes include blood loss, destruction of red blood cells, or lack of production. Poisoning is another potential cause of spotted gums in cats. Exposure to toxins like antifreeze can damage red blood cells and lead to anemic gums.

Spots on a cat’s gums may also indicate gingivitis or inflammation of the gums from plaque and tartar buildup. Bacterial plaque irritates the gums and causes swelling, redness and bleeding. As gingivitis worsens, ulcers, gum recession and pus pockets may occur, leading to a spotted appearance. Regular dental cleanings and plaque removal can prevent this.

If a cat’s gums appear mottled or spotted, it’s important to take them to the vet for an examination. The specific cause will determine the treatment. Spotting caused by benign lentigo requires no treatment, while anemia or gingivitis will need medical care. Catching the underlying issue early is key to prevent ongoing complications.

When to See the Vet

Certain gum color changes in cats require prompt veterinary attention. If your cat’s gums are pale, white, blue, purple, or yellow, you should take them to the vet right away. These gum colors can indicate potentially serious health issues.

Pale gums or gums that are losing their pink color can signify anemia, blood loss, or circulatory problems. Bright red gums throughout the mouth may indicate poisoning or exposure to toxins. Blue or purple gums signal low oxygen levels and respiratory distress. Yellow gums can point to liver disease or blockages in the bile duct. In addition, gums that are spotted or patchy in color can mean internal bleeding.

It’s crucial to have a veterinarian examine your cat whenever you notice these types of gum color changes. Prompt diagnosis and treatment is necessary, as these conditions can worsen quickly without medical intervention. Your vet will be able to run tests to determine the underlying cause and provide appropriate care to address the issue.

While gum color can be an indicator of health problems, always consider it in combination with other symptoms your cat may be exhibiting. Changes in gum color alone do not necessarily confirm disease. But abnormal gum colors, especially when paired with lethargy, appetite changes, or other signs of illness, do warrant a timely vet visit. Monitoring your cat’s gums and contacting your vet with concerns can help catch issues early.


In summary, a cat’s gum color can provide important clues about their health. Normal healthy gums should be pink. However, gum discoloration can signify issues like anemia, poor circulation, infection, liver disease or poisoning. Some key colors to watch out for are pale gums, bright red gums, blue/purple gums, yellow gums, white gums or spotting. It’s important for cat owners to regularly monitor their cat’s gum color and watch for any changes. Unusual gum colors, especially when combined with other symptoms, should prompt a veterinary visit to diagnose and treat any underlying conditions. By staying vigilant about your cat’s gum health, you can help detect problems early and get them the care they need.
