Is Your Cat’s Gum Color a Health Warning Sign?

Introduction

Anemia is a common condition in cats that occurs when there is a reduced number of red blood cells or hemoglobin in the blood. This can make it more difficult for the blood to carry oxygen to the body’s tissues. Anemia can range from mild to life-threatening depending on the underlying cause.

One of the quickest ways to check for anemia in cats is by examining the color of their gums. The gums can provide visible cues about the oxygen levels in the blood. Healthy pink gums indicate adequate red blood cells, while pale or white gums often signal anemia. Regularly monitoring your cat’s gums can help catch anemia early before it progresses.

This article will cover how to identify healthy versus unhealthy gum colors in cats. We’ll discuss what gum colors may indicate anemia, normal gum refill time, and when you should take your cat to the veterinarian. With knowledge of your cat’s gums, you can be alert to signs of anemia and seek prompt treatment.

What is Anemia?

Anemia is defined as a reduced number of red blood cells (RBCs) or reduced hemoglobin in the blood. Hemoglobin is the protein within RBCs that carries oxygen to the body’s tissues. Anemia results when the number or size of RBCs, or the hemoglobin concentration, falls below an established cut-off value.

There are several potential causes of anemia in cats:

Anemia can arise quickly with acute blood loss, or develop slowly with chronic issues impairing RBC production or lifespan.

Signs of Anemia

Some of the most common signs of anemia in cats include:

  • Pale gums – The gums will appear lighter pink or almost white in color instead of a healthy pink color.

  • Lethargy – The cat will have less energy and be less active than usual.

  • Weakness – The cat may have trouble standing up, walking, jumping, or playing.

  • Rapid breathing and heartbeat – To compensate for the lack of oxygen being carried in the blood, the cat may breathe faster and have an elevated heart rate.

Other possible signs include decreased appetite, weight loss, vomiting, diarrhea, and restlessness or irritability. Severely anemic cats may collapse or have seizures. Anemia can develop slowly over time or come on more suddenly in acute cases.

If your cat is displaying any of these signs, it’s important to have them evaluated by a veterinarian as soon as possible. The specific symptoms and their severity will depend on the underlying cause and extent of the anemia.

Checking Your Cat’s Gums

One of the easiest ways to check for anemia in cats is to look at the color and refill time of your cat’s gums. Healthy feline gums should be pink in color. If your cat’s gums look very pale pink or white, this can be a sign of anemia.

You can check the refill time of your cat’s gums by gently pressing down on their gums with your finger. The gums should quickly spring back to their normal pink color once you release the pressure. With anemic cats, the gums will take 1-2 seconds or longer to return to their normal color. This is because anemic cats have less red blood cells circulating to bring that pink color back.

Checking gum color and refill time is a simple at-home method to get an initial suspicion of feline anemia. However, only a veterinarian can diagnose anemia through blood tests. If you notice any signs of unhealthy gums, schedule a vet visit for your cat.

Healthy Gum Color

A healthy cat’s gums should be pink to coral in color. This indicates good circulation and oxygenation. According to Fuzzy Rescue, “The gums receive blood flow from the heart, which provides oxygen. When blood flow is strong, the gums will appear very pink.”

Some breeds may have pigmentation in their gums that leads to spots or flecks of black, brown, or blue. This pigmentation is normal and not a cause for concern.

Kittens often have lighter colored gums since their bodies are still developing. But generally, “a nice bubble gum pink color is ideal” for adult cat gums.

As long as your cat’s gums are a pinkish hue and free of discharge or swelling, that is a sign of good health. But it’s important to continue monitoring their gum color for any changes that may require veterinary attention.

Unhealthy Gum Color

Unhealthy gum colors can indicate anemia or other serious health issues in cats. Some key colors to look out for include:

White: Very pale or white gums often signal anemia or decreased red blood cells. Anemia prevents adequate oxygen transportation in the bloodstream (source).

Yellow: Yellow gums may indicate jaundice and liver disease, which prevents the liver from properly clearing bilirubin from the blood (source).

Blue: Bluish gums are a clear warning sign of oxygen deprivation and serious, life-threatening issues like heart failure or respiratory distress (source).

Brick-red: Gums that appear brick-red can signal poisoning or exposure to toxins, which may be present in common household items like antifreeze or rodenticides (source).

Gum Refill Time

The gum refill time, also known as the capillary refill time (CRT), is an important indicator of your cat’s hydration and circulation status. To check the gum refill time:

  1. Lift your cat’s upper lip to expose their gums.
  2. Apply gentle pressure to the gums for 2-3 seconds using your finger. The gums should blanch and lose color.
  3. Release the pressure and start counting seconds.
  4. Stop counting when you see the natural pink color return to the gums.

In healthy cats, the normal gum refill time is 1-2 seconds (source). If it takes longer than 2 seconds for your cat’s gums to regain color, it could be a sign of anemia or dehydration. A gum refill time of over 4 seconds is considered an emergency and requires immediate veterinary care (source).

When to See a Vet

You should take your cat to the vet immediately if you suspect severe anemia. Pale gums, lethargy, weakness, and collapse are signs of a severe drop in red blood cell levels that requires urgent veterinary care. Severely anemic cats are at risk of shock and death without prompt treatment.

According to VCA Hospitals, “Severely anemic cats may collapse. These cats need immediate veterinary care, including intravenous fluids and blood transfusions in some cases.” https://vcahospitals.com/know-your-pet/anemia-in-cats

As Cornell University College of Veterinary Medicine states, “A cat that is extremely lethargic or collapses should be evaluated by a veterinarian immediately.” https://www.vet.cornell.edu/departments-centers-and-institutes/cornell-feline-health-center/health-information/feline-health-topics/anemia

Prompt veterinary treatment is essential for survival in cases of severe anemia. Don’t delay if your cat is showing signs of a dangerously low red blood cell count.

Diagnosis and Treatment

To diagnose anemia, a veterinarian will first perform a complete physical exam and obtain a medical history. They will check your cat’s gums, feeling for tackiness and looking at the color. Bloodwork will also be done, including a packed cell volume (PCV) test to check red blood cell levels (https://vcahospitals.com/know-your-pet/anemia-in-cats). The PCV test involves spinning down a sample of your cat’s blood in a centrifuge to separate the plasma from the red blood cells. A low PCV indicates anemia.

Other diagnostic tests like a complete blood count, biochemical profile, urinalysis or X-rays may be performed to check for issues like internal bleeding or inflammation. Specific tests to look for the cause of the anemia may be needed, like FeLV/FIV tests, Coombs test or bone marrow biopsy (https://www.merckvetmanual.com/cat-owners/blood-disorders-of-cats/anemia-in-cats).

Treatment focuses on addressing the underlying cause of the anemia. This may include supplements, diet changes, medications, blood transfusions or surgery. Iron supplements may be given for iron-deficiency anemia. Immunosuppressive drugs can treat some causes like autoimmune disorders. Any parasites, infections, wounds or bleeding disorders must be treated. Ongoing monitoring and follow-up testing is key to ensure the anemia is responding to treatment.

Prevention

There are several steps cat owners can take to help prevent anemia in their cats:

Get regular wellness checks with your veterinarian. Annual exams allow the vet to check your cat’s overall health and look for any underlying issues. Bloodwork done as part of the exam can catch anemia early before symptoms appear.

Feed your cat a high-quality cat food that contains all the necessary nutrients. Anemia can be caused by nutritional deficiencies, so a balanced diet is important. According to Beloved Pet, cats with anemia may benefit from supplements containing iron, vitamin B12, folate, and copper as recommended by your vet.

Avoid exposing your cat to toxins like antifreeze, lead, zinc, and onion/garlic powders which can damage red blood cells. Keep household chemicals locked away and supervise your cat outside.

Prevent injuries by keeping your cat indoors and providing safe spaces and toys. Injuries that lead to blood loss can cause anemia.

Control fleas, ticks, and worms through preventatives. Parasitic infections are a common cause of anemia in cats.
