What can raise leukocytes in a cat? - briefly
Infections and inflammation are primary factors that can elevate leukocyte levels in cats. Other potential causes include certain diseases, stress, and some medications.
What can raise leukocytes in a cat? - in detail
Leukocytosis, an elevated white blood cell count, in cats can be indicative of various conditions and diseases. Understanding the potential causes is crucial for proper diagnosis and treatment.
Infections are among the most common reasons for leukocytosis in cats. Bacterial infections, such as those caused by Bartonella species or Mycoplasma, can trigger an increase in white blood cells as the body's immune system responds to fight off the pathogens. Viral infections, including feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV), can also lead to elevated leukocyte levels. Parasitic infestations, such as those caused by intestinal worms or external parasites like fleas and ticks, can likewise contribute to an increased white blood cell count.
Inflammatory conditions, both acute and chronic, can also raise leukocytes in cats. Inflammation of the respiratory tract, gastrointestinal system, or other organs often results in a higher white blood cell count as the body attempts to combat the inflammation. Allergic reactions and autoimmune disorders can also lead to leukocytosis by stimulating an immune response.
Stress and certain medications can temporarily elevate white blood cell counts in cats. Corticosteroids, commonly used to manage inflammatory conditions, can increase leukocyte levels as a side effect of their anti-inflammatory action. Prolonged stress or anxiety can also stimulate the production of white blood cells.
Neoplasia, or the presence of cancerous growths, is another significant cause of leukocytosis in cats. Certain types of cancer, such as lymphoma and leukemia, can directly affect white blood cell production and lead to elevated counts. Additionally, some cancers may produce substances that stimulate the bone marrow to increase white blood cell production.
It is essential to note that while leukocytosis can be a sign of an underlying health issue, it does not always indicate a serious condition. A thorough veterinary examination, including a complete blood count (CBC) and additional diagnostic tests if necessary, is crucial for determining the cause of elevated white blood cell counts in cats. Early detection and appropriate treatment can significantly improve outcomes and overall feline health.
