Feline infectious anemia from Mycoplasma haemofelis causes significant welfare harm through severe anemia, requiring prompt diagnosis and antibiotic treatment for good welfare outcomes.
Feline infectious anemia causes significant suffering from severe anemia - weakness so profound that affected cats cannot stand, pallor indicating desperate shortage of oxygen-carrying red blood cells, and the respiratory effort of trying to compensate with increased breathing. Cats with severe anemia are clearly distressed and unwell. Without treatment, the condition can be fatal. Prompt diagnosis and antibiotic treatment produces good outcomes in most cases, and the welfare improvement with treatment is rapid. Flea and tick control prevents transmission and is the most effective preventive measure for a potentially life-threatening but highly treatable condition.
