Splenomegaly in Cats

Splenomegaly refers to the enlargement of the spleen. This medical condition can occur in all breeds and genders, and is not usually directly related to the spleen, but rather a symptom of another disease or condition. Treatment options will be recommended based upon the cause of the splenomegaly.

Symptoms and Types

An enlarged spleen may lead to such symptoms as:

  • Diarrhea
  • Vomiting
  • Lack of appetite
  • Abdominal pain
  • Lethargy and reduced activity
  • Weakness, and possibly collapse


A variety of conditions are known to cause an enlarged spleen including an abdominal injury, infectious disorders, inflammatory bowel disease, bacterial infection, cell tumors of the spleen, and other immune disorders. While these are some of the most common causes, the medical causes for an enlarged spleen are not directly related to the spleen itself, but rather a symptom of another disease or condition.


Upon examination, a prominent spleen or a protruding abdomen may be noticed. A fine needle aspiration may then be used to diagnose the spleen disorder. Ultrasounds and X-rays may also be used to view the spleen and surrounding areas for abnormalities. In addition to imaging, blood work will give a comprehensive review of all possible underlying medical issues.
