Hemotropic mycoplasmas cause feline infectious anemia, a potentially life-threatening blood infection that severely compromises welfare through progressive blood cell destruction.
Feline infectious anemia causes suffering through progressive red blood cell destruction leading to anemia, with the same welfare consequences as other anemia-causing conditions - weakness, breathlessness, and cardiovascular compromise. Cats may develop severe anemia rapidly in acute infections. The combination of systemic infection and anemia creates significant metabolic stress. Affected cats lose normal energy and engagement with their environment. Blood transfusions, while potentially life-saving, require anesthesia or heavy sedation and carry their own procedural welfare costs. Treatment with doxycycline is effective but requires prolonged courses, and carriers that never fully clear the organism face stress-related reactivation. Prevention through flea and tick control is straightforward and eliminates the primary transmission route.
