Aplastic anemia in cats – clinicopathological features and associated disease conditions 1996–2004

A retrospective study of 128 feline bone marrow reports identified 13 cases of aplastic anemia. Clinical diagnoses included chronic renal failure (n = 5), feline leukemia virus infection (n = 2), hyperthyroidism treated with methimazole (n = 1) and idiopathic aplastic anemia (n = 5). In some cats, starvation may play a role in the development of marrow aplasia. Some cats with aplastic anemia can have prolonged survival without resolution of the pancytopenia.
