Understanding Blood Thickening in Cats
When it comes to the health of our feline friends, it’s important to be aware of potential issues that can arise, such as blood thickening in cats. One condition that can lead to blood thickening is polycythemia. Let’s explore what polycythemia is and the different types that can affect cats.
What is Polycythemia in Cats?
Polycythemia in cats is a condition characterized by an abnormally high number of red blood cells (RBCs), which leads to the thickening of the blood. This thickening can make it difficult for the blood to flow through smaller veins and capillaries, resulting in poor oxygen delivery to tissues and severe circulatory problems, including heart failure (PetMD).
Types of Polycythemias in Cats
There are several types of polycythemias that can affect cats, each with different causes and implications for the cat’s health. These types include:
-
Absolute Polycythemia: Absolute polycythemia is further classified into primary and secondary polycythemia. Primary polycythemia occurs when there is uncontrolled production of RBCs by the bone marrow. Secondary polycythemia, on the other hand, is caused by conditions that increase the production of erythropoietin, a hormone that stimulates RBC production.
-
Relative Polycythemia: Relative polycythemia is different from absolute polycythemia in that it is caused by dehydration. When a cat becomes dehydrated, there is a decrease in the liquid component of the blood, leading to a relative increase in the concentration of RBCs. This gives the appearance of polycythemia, but it is not due to an actual increase in the number of RBCs.
-
Transient Polycythemia: Transient polycythemia is a short-lived condition that occurs due to spleen contraction caused by excitement or stress. This contraction leads to a temporary increase in the concentration of RBCs in the blood. Once the excitement or stress subsides, the spleen returns to its normal size and the blood count returns to normal levels (PetMD).
By understanding the different types of polycythemia in cats, pet owners can be better equipped to recognize the symptoms and seek appropriate veterinary care. It is important to consult with a veterinarian for an accurate diagnosis and to determine the best course of treatment for your cat’s specific condition.
Symptoms and Causes
When it comes to thickened blood in cats, it’s important to recognize the symptoms of polycythemia and understand the common causes behind this condition.
Recognizing Symptoms of Polycythemia
Symptoms of polycythemia in cats can vary depending on the underlying cause and severity of the condition. Some common signs to watch out for include:
- Lethargy and weakness
- Red gums or skin
- Lack of coordination
- Excessive thirst and urination

Common Causes of Blood Thickening
Several factors can contribute to the thickening of blood in cats. Understanding these causes can help identify potential risk factors and prevent complications. Some common causes include:
-
Dehydration: Dehydration is the most common cause of polycythemia in cats. It occurs when there is a decrease in fluid intake or excessive fluid loss through conditions such as vomiting, diarrhea, or decreased water intake (PetMD). The lack of fluids can lead to an increase in red blood cells (RBCs) in proportion to the fluid in the blood. To prevent dehydration, make sure your cat has access to fresh water at all times.
-
Stress: Stress can cause transient polycythemia in cats. When cats experience stress, the spleen contracts, releasing more RBCs into the bloodstream (PetMD). Minimizing stress and providing a calm environment for your cat can help reduce the risk of transient polycythemia.
-
Underlying Medical Conditions: Various medical conditions can contribute to polycythemia in cats. These include chronic heart or lung disease, obesity, cancer, hormonal diseases, kidney disease, and certain types of bone marrow cancer (PetMD). Identifying and treating these underlying conditions can help manage polycythemia effectively.
Understanding the symptoms and causes of blood thickening in cats is crucial for early detection and appropriate management. If you suspect your cat may be experiencing polycythemia, consult a veterinarian for a thorough examination and necessary diagnostic tests. Treating the underlying cause and implementing appropriate interventions, such as blood thinners for cats or targeted therapies, can help regulate blood viscosity and improve your cat’s overall health.
Diagnosis and Testing
To diagnose and understand the causes of blood thickening in cats, a thorough examination and several tests are typically conducted. This process helps veterinarians determine the underlying condition causing the thickening of blood, such as polycythemia.
Physical Examination and Health History
A comprehensive physical examination and detailed health history are crucial in diagnosing blood thickening in cats. The veterinarian will assess the cat’s overall health, noting any symptoms or changes in behavior. They may ask questions about the cat’s diet, exercise routine, and any recent illnesses or injuries. The information gathered during this examination helps provide important insights into potential causes.
Laboratory Tests for Polycythemia
Laboratory tests play a vital role in diagnosing blood thickening in cats. These tests help evaluate the complete blood count (CBC), biochemistry profile, and urinalysis. By analyzing blood samples, veterinarians can identify abnormalities in red blood cell count, hemoglobin levels, and hematocrit. These measurements provide valuable insights into the cat’s blood composition and can help determine the presence of polycythemia.
In some cases, additional tests may be necessary to confirm a diagnosis or rule out other possible causes. These tests may include an echocardiogram to assess heart function and structure, X-rays to evaluate the chest and abdomen, and even bone marrow sampling for further evaluation.
By conducting a thorough physical examination and performing laboratory tests, veterinarians can make an accurate diagnosis and develop an appropriate treatment plan for blood thickening in cats. It’s important to consult with a veterinarian to ensure proper diagnosis and management of this condition.
Treatment Options
When it comes to treating thickened blood in cats, the approach will depend on the underlying cause and the specific condition present, such as polycythemia. Treatment options aim to reduce the excessive red blood cell count, improve blood flow, and alleviate symptoms. Here are two common treatment approaches for managing thickened blood in cats: intravenous (IV) fluids and oxygen therapy, and phlebotomy and medication.
Intravenous (IV) Fluids and Oxygen Therapy
In cases where a cat with thickened blood is dehydrated or experiencing low blood oxygen saturation, intravenous (IV) fluids and oxygen therapy may be utilized. IV fluids are administered to address dehydration and improve overall blood circulation. This helps to optimize blood flow and reduce the viscosity of the blood, making it easier for nutrients and oxygen to be transported throughout the body.
Oxygen therapy is another important aspect of treatment. Providing supplemental oxygen helps to increase the oxygen levels in the blood, which is essential for maintaining the health of vital organs and tissues. By ensuring adequate oxygenation, oxygen therapy can help alleviate symptoms associated with thickened blood.
Phlebotomy and Medication
Phlebotomy, a procedure similar to blood donation in humans, is commonly used in the treatment of certain conditions like polycythemia vera. It involves the removal of a calculated volume of blood through an intravenous catheter. The purpose of phlebotomy is to reduce the number of circulating red blood cells and decrease blood viscosity. This procedure helps to improve blood flow and alleviate symptoms associated with thickened blood.
In addition to phlebotomy, medication may be prescribed to manage certain conditions that cause blood thickening. For example, hydroxyurea, a chemotherapy drug, may be used to slow down the bone marrow’s production of red blood cells. By reducing the excessive production of red blood cells, hydroxyurea helps to normalize blood viscosity and improve overall circulation. It is important to closely monitor cats undergoing this treatment for potential side effects such as vomiting, loss of appetite, diarrhea, and potential suppression of white blood cell production.
It is essential to consult with a veterinarian to determine the most appropriate treatment plan for your cat. Treatment options may vary depending on the specific condition causing the thickened blood and the overall health of your feline companion. Regular follow-up visits and monitoring are crucial to assess the response to treatment and make any necessary adjustments.

Polycythemia Vera in Cats
Polycythemia vera is a blood disorder that affects older cats, leading to abnormal blood thickening due to an increase in red blood cell production by the bone marrow (PetMD). This condition can have significant health implications for cats, requiring proper understanding and management.
Characteristics of Polycythemia Vera
In cats with polycythemia vera, blood testing typically reveals an increase in red blood cell mass. In about 50 percent of cases, an increased number of white blood cells, known as leukocytosis, may also be present. These changes contribute to the thickening of blood and may lead to complications such as blood clots and impaired circulation.
Managing Polycythemia Vera
The treatment approach for polycythemia vera in cats involves multiple strategies to address the underlying cause and manage the symptoms. The initial step often includes a procedure called phlebotomy, where a fair amount of blood is drawn from the cat, reducing blood viscosity. The removed blood is then replaced with intravenous fluids to maintain hydration and prevent further complications (PetMD).
Long-term therapy for polycythemia vera in cats may involve the use of an antineoplastic drug called hydroxyurea. This medication helps suppress the overproduction of red blood cells in the bone marrow, reducing blood thickness and the risk of clot formation.
Regular follow-up exams are crucial for cats undergoing treatment for polycythemia vera, particularly when using hydroxyurea. Monitoring the cat’s response to therapy and assessing any potential side effects, such as bone marrow suppression, is essential. Adjustments in medication dosage and frequency may be necessary based on the cat’s condition and ongoing evaluation of complete blood counts (PetMD, VCA Hospitals).
By understanding the characteristics and management of polycythemia vera in cats, pet owners can work closely with their veterinarians to provide the necessary care and support for their feline companions. Regular monitoring and adherence to the prescribed treatment plan are crucial for maintaining the cat’s health and managing the blood thickening associated with this condition.
Follow-Up and Monitoring
After the diagnosis of polycythemia in cats and the initiation of treatment, regular follow-up exams and monitoring are essential to ensure the well-being of your feline companion. The importance of these follow-up visits cannot be overstated, as they allow for the evaluation of treatment effectiveness, adjustment of medications if necessary, and early detection of any potential complications.
Importance of Regular Exams
