Disseminated Intravascular Coagulation (DIC) in Cats: A 2025 Veterinary Guide to Diagnosis, Treatment & Care 🐱🩸

By Dr. Duncan Houston, BVSc

Disseminated Intravascular Coagulation (DIC) is a severe, life-threatening condition in cats characterized by widespread clotting within blood vessels, leading to the consumption of clotting factors and subsequent bleeding. Understanding the causes, recognizing the symptoms, and seeking prompt veterinary care are crucial for managing this complex disorder. This comprehensive 2025 guide provides insights into DIC in cats, including its causes, symptoms, diagnosis, treatment, and prevention.

Understanding DIC in Cats 🧬

DIC is not a disease itself but a complication arising from various underlying conditions that trigger abnormal activation of the coagulation cascade. This leads to the formation of microthrombi throughout the vasculature, consuming platelets and clotting factors, and resulting in both thrombosis and hemorrhage.

Common Underlying Causes

• Sepsis: Severe systemic infections can trigger widespread inflammation and coagulation.
• Neoplasia: Certain cancers, such as lymphoma or hemangiosarcoma, can initiate DIC.
• Trauma: Significant injuries or surgeries may lead to DIC.
• Pancreatitis: Inflammation of the pancreas can disrupt normal coagulation.
• Liver disease: Impaired liver function affects the production of clotting factors.
• Heatstroke: Elevated body temperatures can damage tissues and activate clotting pathways.

It's essential to identify and address the primary condition to effectively manage DIC.

Recognizing the Symptoms 🔍

Symptoms of DIC in cats can be subtle initially but may progress rapidly. Common signs include:

• Unusual bleeding from gums, nose, or injection sites
• Presence of petechiae (small red or purple spots) on the skin
• Lethargy and weakness
• Rapid breathing or difficulty breathing
• Blood in urine or feces
• Signs of organ dysfunction, such as jaundice or neurological deficits

These symptoms warrant immediate veterinary attention.

Diagnosis 🩺

Diagnosing DIC involves a combination of clinical evaluation and laboratory tests:

• Complete blood count (CBC): May reveal anemia, thrombocytopenia, or leukocytosis.
• Coagulation profile: Prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT).
• Fibrin degradation products (FDPs) and D-dimer levels: Elevated levels indicate increased fibrinolysis.
• Blood smear: Presence of schistocytes (fragmented red blood cells).
• Assessment of underlying conditions: Imaging, cultures, or specific tests as needed.

Early and accurate diagnosis is critical for effective treatment.

Treatment Options 💊

Treatment of DIC focuses on addressing the underlying cause and providing supportive care:

• Stabilization: Intravenous fluids to maintain blood pressure and tissue perfusion.
• Blood products: Transfusions of fresh frozen plasma or platelets to replenish clotting factors.
• Oxygen therapy: To support oxygenation in cases of respiratory distress.
• Medications: Antibiotics for infections, anti-inflammatory drugs, or other specific therapies based on the primary condition.

Close monitoring in an intensive care setting is often required.

Prognosis 📈

The prognosis for cats with DIC is guarded and depends on the severity of the condition and the underlying cause. Early detection and prompt, aggressive treatment improve the chances of recovery, but the mortality rate remains high.

Preventive Measures 🛡️

Preventing DIC involves managing and monitoring conditions that can lead to its development:

• Regular veterinary check-ups: Early detection of diseases like cancer or infections.
• Prompt treatment of infections and inflammatory conditions: To prevent progression to systemic involvement.
• Careful monitoring during and after surgeries: Especially in high-risk patients.
• Maintaining a healthy environment: To reduce the risk of trauma and heatstroke.

Proactive health management is key to reducing the risk of DIC.

When to Consult a Veterinarian 👩‍⚕️

Immediate veterinary attention is necessary if your cat exhibits:

• Unexplained bleeding or bruising
• Sudden lethargy or collapse
• Difficulty breathing
• Signs of organ dysfunction, such as jaundice or seizures

Early intervention can be life-saving.
