Cat Feline Infectious Anemia Welfare

Feline infectious anemia (Mycoplasma haemofelis) is a bacterial infection destroying red blood cells in cats. Understanding this condition enables early treatment of a genuinely distressing illness.

Key Facts

Mycoplasma haemofelis attaches to red blood cells, triggering their immune-mediated destruction
Transmission occurs through flea bites, cat bites, or blood transfusion from carrier cats
Signs include lethargy, pale or yellow mucous membranes, weakness, and rapid breathing
Treatment with doxycycline and supportive care including transfusions for severely anemic cats is effective
Some cats become chronic carriers without clinical signs after recovery from acute infection

Welfare Considerations

Cats with acute feline infectious anemia experience profound weakness and breathlessness from severe anemia - a genuinely distressing condition. The immune-mediated destruction of red blood cells proceeds rapidly without treatment, and severely affected cats deteriorate within days. Prompt diagnosis and doxycycline treatment is effective in most cases. Flea prevention is critical for primary prevention since fleas are the main transmission vector. Welfare-conscious cat management that includes consistent flea control reduces exposure for outdoor and multi-cat household cats significantly.

What You Can Do

Maintain consistent monthly flea prevention for all cats, particularly outdoor and multi-cat household cats
Seek urgent veterinary care for any cat showing extreme lethargy or pale/yellow gums
Test newly acquired cats for Mycoplasma haemofelis carrier status before introducing to resident cats
Ensure blood donors in feline transfusion programs are tested and cleared for haemoplasma infection
