Veterinarians use the term cyanosis to describe blue skin and gums in cats. This condition can appear when your cat’s heart is not effectively pumping enough blood to circulate his body. Hemoglobin is the protein that is responsible for transporting blood throughout your cat’s body. Healthy hemoglobin is red in color. When there is not enough oxygen being delivered throughout the body, the result is a blueish tint to skin and mucous membranes.

If you are like most cat owners, your cat’s health is of the utmost importance. While most cats are generally healthy, there are times where unusual symptoms can occur. Blue tinted skin and mucous membranes in your cat can be troubling to see. This is not caused by disease, but is a direct result of an underlying condition affecting your cat’s health.

Cyanosis is often a frightening symptom for pet owners to see in their beloved cat. Below is a list of other symptoms that may occur along with the discoloration of skin and gums. 

Veterinarians classify cyanosis into two types:

There are several different causes for blue skin and mucous membranes to occur in your cat. Here are some of the most common causes in domestic cats. 

Your veterinarian will use a variety of tools to diagnose the cause of cyanosis in your cat. First, he will take a detailed medical history from you regarding your cat’s health. It is important to include information such as onset of symptoms, severity of symptoms and how your cat is behaving. After taking a history, your doctor will examine your cat. A blood test will tell your doctor how your cat’s hemoglobin is being affected and if any infections are present. A urine sample will also be taken and analyzed. 

If cyanosis is visible to your doctor, he will attempt to increase your cat’s oxygen levels. He may place your cat in a special oxygen rich chamber to bring his levels up to normal. An ultrasound may be able to reveal fluid in the areas surrounding your cat’s lungs. If fluid does exist, your doctor may perform a needle procedure to remove the fluid so your cat can breathe better.

When a heart defect is suspected to be the cause of cyanosis, an echocardiogram may be performed. This test can give your doctor detailed information about the structure of the heart.

The treatment plan for cyanosis in your cat will depend on the cause of the condition. Here are a few ways this condition may be treated and managed:

When oxygen levels are low due to illness such as pneumonia, medications such as antibiotics may be given. If your cat’s blood sugar is low, glucose may be administered to relieve symptoms. Diuretics are often given to help remove fluid if congenital heart failure is diagnosed

A fine needle aspiration may be performed to remove fluid from the chest wall. In addition, surgery may be required to repair blockages, remove tumors or remove foreign objects restricting blood flow. 

The recovery process will depend on the cause of cyanosis and the treatment your veterinarian uses. There are no at home remedies you can use to treat this condition. It can be a serious condition with life-threatening consequences for your cat, since his body is not receiving enough oxygen through his blood.

If surgery has been performed, your veterinarian will give you medications to use afterward and a detailed account on how to care for your cat once he goes home. Needle aspirations usually do not require long-term or special care. In these cases, the cat’s oxygen levels rise as soon as the fluid is removed. 

Your veterinarian may send you home with a special diet or nutritional supplements for your cat. Be sure to follow his orders exactly to obtain the best possible outcome for your pet. 

Your doctor may also recommend that you restrict your cat’s activity level until he becomes stronger and more stable.
