Understanding Blood Thickening in Cats
When it comes to the health of our feline companions, understanding conditions like blood thickening, also known as hypercoagulability, is crucial. Hypercoagulability refers to a state in which the blood has an increased tendency to form clots. In cats, this condition can have severe consequences and may lead to various health disorders.
Hypercoagulability in Felines
Hypercoagulability in cats can result from various factors, including stickier than normal blood platelets, deficiencies in antithrombin (a natural anticoagulant), decreased removal of coagulation factors, or defective fibrinolysis (the process of breaking down blood clots) (PetMD). Cats with cardiomyopathy often exhibit hypercoagulability, even in the absence of congestive heart failure or arterial thromboembolism (PubMed). Understanding the causes and underlying mechanisms of hypercoagulability is important for managing and treating this condition effectively.
Causes of Blood Thickening
The causes of hypercoagulability in cats can vary. Stickier blood platelets, for example, can lead to abnormal clotting and potentially cause thrombosis in arteries, veins, or the heart, resulting in a loss of blood supply to affected areas (PetMD). Deficiencies in antithrombin, which help regulate the clotting process, can also contribute to blood thickening in cats. Additionally, decreased removal of coagulation factors or defective fibrinolysis can disrupt the delicate balance of the clotting system and result in abnormal blood clot formation.
By understanding the causes of blood thickening in cats, veterinarians can better diagnose and manage this condition. Diagnostic tests play a crucial role in identifying hypercoagulability and determining the appropriate treatment options. In the following section, we will explore the symptoms and diagnostic tests used to detect hypercoagulability in cats.

Diagnostic Tests for Cats
To confirm hypercoagulability in cats, veterinarians employ various diagnostic tests to assess their blood clotting function and overall health. These tests can help determine the underlying cause and guide appropriate treatment. Common diagnostic tests include:
- Activated partial thromboplastin time (APTT): This test evaluates the time it takes for blood to clot and can help detect abnormalities in the coagulation process.
- Blood chemical profile: This comprehensive blood test assesses vital organ function and can indicate any abnormal levels or imbalances.
- Complete blood count (CBC): This test provides information about the number and types of blood cells, helping identify any abnormalities.
- Comprehensive urinalysis: A urine test can give insights into kidney function and overall health.
- Chest x-rays: X-rays can help evaluate the heart and lungs for any abnormalities that may contribute to hypercoagulability.
- Abdominal ultrasound: This imaging technique can provide detailed information about abdominal organs and identify potential issues.
- Echocardiogram: An ultrasound of the heart can reveal abnormalities that may contribute to blood clot formation.
- Angiography: This procedure involves injecting a contrast agent into blood vessels to visualize any blockages or abnormalities.
- Nuclear perfusion scintigraphy: This specialized imaging technique assesses blood flow to various organs and can help identify areas of reduced blood supply.
These diagnostic tests, along with a thorough physical examination and medical history evaluation, enable veterinarians to accurately diagnose hypercoagulability in cats. Early detection allows for timely intervention and appropriate treatment.
Once a diagnosis is confirmed, treatment options can be explored to manage the condition effectively. For more information on the treatment approaches for hypercoagulability in cats, continue reading our article on blood thinners for cats.
Treatment Options
Managing Hypercoagulability
When it comes to managing hypercoagulability in cats, effective treatment is crucial to prevent severe health disorders. Hypercoagulability refers to the abnormal clotting of blood due to various factors, such as stickier than normal blood platelets, deficiencies in antithrombin, decreased removal of coagulation factors, or defective fibrinolysis.
To effectively manage hypercoagulability in cats, treatment options may include:
-
Anticoagulant Therapy: Anticoagulant medication may be prescribed by a veterinarian to prevent excessive clot formation and reduce the risk of thrombosis. Commonly used anticoagulants for cats include aspirin and heparin. It’s important to note that the use of anticoagulant medication requires careful monitoring and should only be administered under the guidance of a veterinarian.
-
Fluid Therapy: Fluid therapy may be recommended to maintain hydration and optimize blood flow. Adequate hydration can help prevent the formation of blood clots and reduce the risk of complications associated with hypercoagulability.
Therapeutic Approaches
In addition to anticoagulant therapy and fluid therapy, other therapeutic approaches can be beneficial in managing hypercoagulability in cats:
-
Activity Restriction: Cats diagnosed with hypercoagulability may be required to have restricted activity or bed rest. Limiting physical exertion helps minimize the risk of clot formation and reduces the strain on the cardiovascular system.
-
Oxygen Cage Therapy: In cases where hypercoagulability is associated with a compromised respiratory or cardiovascular system, oxygen cage therapy may be necessary. This therapy provides supplemental oxygen to support the cat’s respiratory function and help optimize blood oxygen levels.
-
Medication: Depending on the underlying cause of hypercoagulability, additional medications may be prescribed to address specific conditions. For example, if the hypercoagulability is secondary to an underlying heart condition, medications to manage the heart disease may be recommended.
It is essential to work closely with a veterinarian to determine the most appropriate treatment plan for your cat’s specific needs. Regular follow-up visits and monitoring are crucial to ensure the effectiveness of the chosen treatment approach and adjust the management plan as necessary.
By implementing an appropriate treatment plan, you can help manage hypercoagulability in your cat and reduce the risk of complications associated with abnormal clotting. However, it’s important to note that the prognosis and long-term care for cats with hypercoagulability can vary depending on the underlying cause and individual response to treatment. Regular veterinary care and ongoing monitoring are essential to maintain your cat’s overall health and well-being.
Prognosis and Long-Term Care
When it comes to feline hypercoagulability, the prognosis and long-term care for affected cats can vary depending on various factors. Understanding the survival rates and providing appropriate care are essential for ensuring the well-being of cats with blood thickening.
Survival Rates
The long-term prognosis for cats with feline hypercoagulability, specifically feline arterial thromboembolism (ATE), is generally guarded to poor. Survival rates can vary depending on the clinical severity and underlying cause. It’s important to note that survival rates may be higher in referral practice settings.
Overall, survival rates of approximately 30% to 40% have been reported for cats with ATE. Negative prognostic indicators for ATE include the presence of a gallop heart rhythm, reduced heart rate, previous occurrence of ATE, having two or more limbs affected, and rectal temperature lower than 37°C (98.6°F) (Today’s Veterinary Practice). Cats with only a single limb affected have higher survival rates, reaching as high as 70% to 80%, especially if some motor function remains at presentation (Today’s Veterinary Practice).
For feline aortic thromboembolism (FATE), the survival rates can also vary. Cats with unilateral occlusion (occlusion of a single limb) tend to have better survival rates, ranging from 70% to 93%, compared to cats with bilateral occlusion (occlusion of both hind limbs), which have lower survival rates of 15% to 35% (NCBI). It’s important to consult with a veterinarian to determine the specific prognosis for an individual cat.
Care for Cats with Blood Thickening
Providing proper care for cats with blood thickening is crucial to their overall well-being. Here are some considerations for the long-term care of cats with feline hypercoagulability:
-
Medication: Cats with blood thickening may require long-term medication to manage the condition. Anticoagulant medications, such as heparin and warfarin, are commonly used to prevent further clot formation. These medications should be administered under the guidance of a veterinarian, as they require careful monitoring and adjustment. Regular blood tests may be necessary to ensure appropriate dosing.
-
Diet and Exercise: A balanced diet and regular exercise are important for maintaining the overall health of cats with blood thickening. Consult with a veterinarian to determine the appropriate diet and exercise regimen for your cat’s specific needs.
-
Follow-up Veterinary Care: Regular veterinary check-ups are essential for monitoring the cat’s condition and adjusting the treatment plan if necessary. These visits allow for ongoing assessment and early detection of any potential complications.
-
Environmental Modifications: Making environmental modifications to ensure the safety and comfort of cats with blood thickening is important. This may include providing soft bedding, avoiding slippery surfaces, and minimizing stressors that can contribute to blood clot formation.
-
Education and Awareness: As a cat owner, it’s essential to educate yourself about feline hypercoagulability and its management. Stay informed about the signs and symptoms of blood clotting disorders and seek veterinary advice promptly if any concerning symptoms arise.
By following these care guidelines and working closely with a veterinarian, you can provide the best possible care for your cat with blood thickening. Regular monitoring, appropriate medication, and a supportive environment can contribute to a better quality of life for cats with feline hypercoagulability.
Feline Arterial Thromboembolism (ATE)
Feline Arterial Thromboembolism (ATE) is a serious condition that affects cats and is characterized by the formation of blood clots in the arteries. This condition is more prevalent in cats with underlying cardiac disease, particularly those with left atrial enlargement due to conditions such as hypertrophic cardiomyopathy (Today’s Veterinary Practice).
Overview of ATE
ATE occurs when a blood clot, also known as a thrombus, forms within the heart and subsequently lodges in one of the arteries, blocking blood flow to the affected area. The most commonly affected arteries in cats with ATE are those supplying the hind limbs. The obstruction of blood flow can lead to severe pain, paralysis, and tissue damage in the affected limbs.
Factors contributing to the development of ATE in cats are described by Virchow’s triad, which consists of endothelial dysfunction, blood stasis, and a hypercoagulable state. In cats with ATE, platelet hyperaggregation has been identified as a significant factor contributing to the hypercoagulable state.
The typical age at presentation for cats with ATE is approximately 8 to 12 years, with male cats being overrepresented. While ATE can affect both pedigreed and non-pedigreed cats, certain pedigree breeds such as Abyssinian, Birman, Ragdoll, Maine Coon, Himalayan, Siamese, and Persian cats have been observed to have a higher incidence of the condition.
Factors Contributing to ATE
The development of ATE in cats is primarily associated with left atrial enlargement caused by significant cardiac disease, most commonly hypertrophic cardiomyopathy. Other forms of cardiomyopathy or congenital defects affecting the left heart can also lead to the formation of ATE. In rare cases, noncardiac conditions such as pulmonary neoplasia with subsequent tumor embolism or infective endocarditis can result in ATE (Today’s Veterinary Practice).
Understanding the factors contributing to ATE is crucial for early detection and management of the condition in cats. By recognizing the risk factors and promptly seeking veterinary care, cat owners can help mitigate the severity and potential complications associated with ATE.
In the next section, we will explore the treatment options available for managing ATE in cats, as well as the long-term prognosis and care for cats affected by this condition.
Feline Aortic Thromboembolism (FATE)
Feline Aortic Thromboembolism (FATE) is a devastating condition in cats where a blood clot becomes lodged in the aortic trifurcation, leading to severe consequences. Understanding FATE and its treatment is crucial for cat owners and veterinarians alike.
Understanding FATE
FATE occurs when a blood clot, usually originating from the heart, becomes lodged in the aortic trifurcation, which is the point where the aorta divides into the iliac arteries. This blockage disrupts blood flow to the hind limbs, resulting in pain, paralysis, and potentially life-threatening complications. Clinical signs, radiography, ECG, and echocardiography are valuable tools for diagnosing FATE (NCBI).
FATE is often associated with underlying cardiac diseases, most commonly hypertrophic cardiomyopathy (HCM). Approximately 12%–21% of cats with HCM may develop FATE. Other conditions such as pulmonary neoplasia and thyroid disease have also been linked to FATE (NCBI).
The potential pathogenesis of FATE is thought to start with cardiac disease that causes abnormal blood turbulence, leading to the formation of micro-clots in the left atrium. These micro-clots can then grow into larger clots that are eventually ejected from the heart and become lodged in the aortic trifurcation.
Treatment for FATE
Prompt diagnosis and immediate treatment are vital for cats with FATE. The outcome of therapy depends largely on early intervention within the first 6 hours from the onset of clinical signs (NCBI). The treatment approaches for FATE primarily focus on managing the condition and preventing further complications.
Anticoagulant therapy plays a critical role in the treatment of FATE. Medications such as heparin and warfarin are commonly used to inhibit blood clotting and prevent the formation of additional clots. The success rate of anticoagulant treatment for FATE is reported to be around 37%–39%.
In some cases, exogenous thrombolytic agents, such as streptokinase or tissue plasminogen activator, may be used to dissolve the blood clot. However, the success rate of thrombolytic therapy for FATE varies between 0% and 33% (NCBI).
It’s important to note that the prognosis for cats with FATE can vary depending on the extent of the clot and the presence of other underlying conditions. The survival rates for cats with unilateral occlusion (70%–93%) are generally better than for those with bilateral occlusion (15%–35%) (NCBI).
Cats recovering from FATE require long-term care and management. Close monitoring of cardiac health, including regular check-ups and echocardiograms, is crucial to detect any potential recurrence or complications. Additionally, your veterinarian may recommend specific medications or dietary adjustments to support your cat’s heart health and reduce the risk of future clot formation.
If you suspect that your cat may be experiencing symptoms of FATE, such as sudden hind limb paralysis or severe pain, it is crucial to seek immediate veterinary attention. Early intervention and appropriate treatment are key in managing this serious condition and improving your cat’s chances of recovery.
