Why does a cat have a blue tongue?

Some pet owners find a blue tongue in a cat. This is an alarming symptom. It does not apply to a single disease, but is a sign of certain pathologies.

Changing the color of the tongue

The color of the mucous membranes depends on the fullness of the blood with carbon dioxide and oxygen. If there is a deficit, then the cat's tongue acquires a bluish color. This phenomenon is called cyanosis. If it is long and persistent, then the cat will feel worse and worse - to death. Blue can become dark, almost black, violet-red.

Why does not always a blue tongue indicate a disease? A cat can just lick a blue thing, and stuck villi will visually change color. In another case, the animal may accidentally lick blueberry juice or dyes. They will temporarily stain the tongue in an unnatural color.

Causes of blue tongue in cats

The tongue takes unnatural shades due to a number of diseases. One of the causes of cyanosis can be congenital heart disease. The color of the cat’s tongue changes after falling from a great height, chest injuries, dog bites, and inflammation. Other reasons:

  • pneumothorax - filling the sternum with air;
  • hydrothorax - accumulation in this area of ​​fluid.

In both cases, the cat is deficient in air. The lungs may stop functioning on the right or left side - partially or completely. If the processes of pneumo-and hydrothorax do not stop, the tongue takes on an increasingly blue tint, and the animal dies from an attack of suffocation.

Cyanosis (a blue tongue in a cat) can develop in minutes or within a few days. The hue at the same time becomes more saturated. In this case, frequent breathing is observed (the animal’s mouth is open at this time) and shortness of breath. Also, the causes of cyanosis can be:

  • Diaphragmatic hernia, when a rupture of the membrane occurs in the peritoneum and the organs fall into the chest. Due to displacement, the lungs do not get enough oxygen in the right amount. This can be determined by examining the cat's tongue, the mucous membranes surrounding it become blue.
  • Infectious peritonitis or FIP, viral leukemia (aka lymphosarcoma). With these conditions, fluid accumulates in the abdominal cavity, the tongue of the animal turns blue.
  • Pulmonary edema is one of the most dangerous diseases. In addition to cyanosis, there is a constant severe shortness of breath, anxiety.
  • Asthma is accompanied by decreased breathing and coughing. Blue tongue and respiratory failure appear with a severe form of the disease.

Often the cause of the appearance of dark blue, almost black spots, may be the usual pigmentation. However, it can be congenital. Spots increase in volume with age. More often fluffy and ginger cats are subject to such a defect. Cyanotic spots can acquire a brownish tint over time.

When the mucous membranes and tongue turn blue, this often indicates heart disease. Brown or gray plaque on the gums indicates pathology of the stomach, lungs and intestines. With gastrointestinal disorders, food can be thrown back with vomiting, staining the mucous membranes.

An alarm should be struck only if there are additional negative signs - refusal to eat, lethargy, apathy, etc. However, you cannot do anything with the animal on your own, in any condition you need to show it to the veterinarian.
