This happens when your cat’s bone marrow doesn’t make enough red blood cells. There may be a drop in the hormone that helps make them or a problem with the bone marrow itself.
The most common cause of nonregenerative anemia is the feline leukemia virus. It can also be caused by:
A poor diet, which causes nutrition problems like not enough iron.
A chronic inflammation or infection, a tumor, liver disease, or hormonal disorder.
Primary leukemia. This is when abnormal white blood cells take over normal cells.
Bone marrow disorders where not enough new blood cells are made.
Myelofibrosis, a progressive disease that leads to bone marrow failure.
This is when your cat has a loss of red blood cells or the red blood cells die too soon. Your cat’s bone marrow makes up for the lost blood cells by making more red blood cells. But it can’t keep up with the loss of cells.
There are two types of regenerative anemia:
This happens when your cat’s immune system destroys its own red blood cells by mistake. This can be hard to spot, so many cats with this kind aren’t diagnosed properly.
