Nonregenerative anemia in cats results from the inability of the bone marrow to respond appropriately to a peripheral deficiency in RBCs. There are many causes of nonregenerative anemia, including primary diseases of the bone marrow and systemic diseases that have secondary effects on the bone marrow. The prognosis is variable: some etiologies are reversible, whereas others may be chronic or fatal.
