Blood transfusions in cats are a critical medical intervention used to treat life-threatening conditions such as severe anemia, blood loss from trauma or surgery, certain clotting disorders, or immune-mediated diseases.
🩸 When Are Blood Transfusions Needed in Cats?
Common indications include:
• Severe anemia (from hemolysis, chronic disease, or bone marrow failure)
• Hemorrhage or trauma
• Surgical blood loss
• Toxin exposure (e.g., onion toxicity)
• Autoimmune hemolytic anemia
• Clotting disorders (like rodenticide poisoning or DIC)
🧬 Feline Blood Types
Cats have three main blood types: A, B, and AB.
• Type A: Most common (especially in domestic shorthairs in North America)
• Type B: Less common, found in certain breeds like British Shorthairs, Devon Rex, and some Australian cats
• Type AB: Very rare.
✅ Outcome and Prognosis
A successful transfusion can be life-saving, but the underlying condition must be addressed for long-term survival. Some cats may need repeat transfusions, especially if they have ongoing disease or hemolysis.
We often have patients referred for anaemia investigations and blood transfusions so are always happy to assist where possible!
