Why does a cat's hemoglobin drop? - briefly
A cat's hemoglobin may drop due to conditions such as anemia, blood loss, or underlying diseases like kidney failure or infections.
Why does a cat's hemoglobin drop? - in detail
A cat’s hemoglobin levels may drop due to various underlying conditions or factors that disrupt the normal production, function, or lifespan of red blood cells. Hemoglobin, a protein in red blood cells, is essential for transporting oxygen throughout the body. A decrease in hemoglobin, often referred to as anemia, can result from blood loss, reduced red blood cell production, or increased destruction of red blood cells. Blood loss can occur due to trauma, surgery, or internal bleeding caused by conditions such as ulcers, tumors, or parasites like fleas or ticks. Chronic diseases, such as kidney failure or liver disease, can impair the production of erythropoietin, a hormone that stimulates red blood cell formation in the bone marrow. Nutritional deficiencies, particularly of iron, vitamin B12, or folic acid, can also hinder red blood cell production. Certain infections, such as feline leukemia virus (FeLV) or feline immunodeficiency virus (FIV), can directly affect the bone marrow or lead to immune-mediated destruction of red blood cells. Additionally, toxins, medications, or autoimmune disorders may cause hemolysis, where red blood cells are destroyed faster than they can be replaced. Identifying the specific cause of low hemoglobin in a cat requires a thorough veterinary evaluation, including blood tests, imaging, and sometimes bone marrow analysis, to determine the appropriate treatment and management plan.
