Bacterial infections: Bacterial infections are a common cause of neutrophilia in cats. Neutrophils are essential in the body's immune response to fight bacterial invasions. Bacterial infections like urinary tract infections, pyometra (uterine infection), skin infections, abscesses, or respiratory infections can lead to an increase in neutrophil production.
Viral infections: Some viral infections can also cause a temporary increase in neutrophil count. Common feline viral infections associated with neutrophilia include feline leukemia virus (FeLV), feline immunodeficiency virus (FIV), and feline infectious peritonitis (FIP).
Inflammatory conditions: Non-infectious inflammatory conditions such as autoimmune disorders, pancreatitis, peritonitis, and trauma can also result in neutrophilia as part of the inflammatory response.
Bone marrow disorders: Bone marrow disorders like leukemia or myelodysplasia can affect the production of neutrophils, leading to abnormally high or low neutrophil counts.
Medications: Certain medications, such as corticosteroids, can cause a transient increase in neutrophil count.
Stress: Severe stress or pain can temporarily elevate neutrophil levels in some cats.
It's crucial to determine the underlying cause of neutrophilia in cats, as different treatments or management strategies may be necessary depending on the specific etiology. Consulting with a veterinarian is essential for proper diagnosis and management of neutrophilia in cats.
