It depends on the cause. It could be a bacterial infection called
hemobartanella (sp?) which is treated with antibiotics. Or an auto-immune
response,
treated with steroids. Or lymphoma, which can be treated with chemo and
steroids.
Or kidney-related, treated with Epogen. Or leukemia-related. And it can be
fatal if not treated, no matter the cause, if it gets serious enough. It has
taken the lives of many of the cats on this list serve. Simon died from anemia,
caused either by his lymphoma or, the oncologist thinks more likely, a sudden
auto-immune response to the lymphoma in which he started killing off his own
red blood cells. You need to take him to a knowledgeable vet. I would not
trust this kind of diagnosis to a run of the mill country vet like we have out
here.
