Abdominal Cavity Inflammation in Cats

ADVERTISEMENT

Peritonitis in Cats

 

The abdominal cavity is lined with a thin, watery membrane, called the peritoneum. When the cat's abdominal cavity, also called the peritoneal cavity, is injured, the peritoneum becomes inflamed. The severity of the inflammation depends on the type of injury the peritoneal cavity has undergone. Peritonitis is frequently a painful condition, and the cat will respond when it is touched on its abdomen.

 

Peritonitis can affect both dogs and cats. To learn more about how it affects dogs, please visit this page in the PetMD health library.

 

Symptoms and Types

 

  • Fever
  • Vomiting
  • Abdominal pain
  • Animal positions itself in a “praying” position for relief of pain
  • Low blood pressure and signs of shock
  • Increased heart rate
  • Possible abnormal heart rhythm (arrhythmia)

 

Causes

 

  • Peritonitis
    • Caused by the spread of a causative agent through the blood
  • Secondary peritonitis (caused by an injury elsewhere in the body)
  • Common form
    • Caused by injury to the abdominal cavity or hollow organs
  • Bacterial or chemical contamination:
    • Opening of surgical sites
    • Penetrating abdominal wounds
    • Blunt abdominal trauma
    • Severe inflammation of the pancreas
    • Filling of the abdomen with pus
    • Liver abscesses (inflamed swelling with pus)
    • Prostatic cysts -- in males, inflamed swelling with pus from the prostate gland
    • Rupture of the gallbladder, urinary bladder, or bile duct

 

Diagnosis

 

Your veterinarian will perform a complete physical exam on your cat, including a chemical blood profile, a complete blood count, a urinalysis, and an electrolyte panel. You will need to give a thorough history of your cat's health, including a background history of symptoms, and possible incidents that might have precipitated this condition. The history you provide may give your veterinarian an indication of whether other organs are causing the condition or are being affected.

 

Radiograph and ultrasound imaging are critical for visualizing the presence of free fluid in the abdomen, free gas in the abdomen, and an abscess, if it is present. A fluid sample taken by abdominocentesis should be done so that a sample can be stored in a vacuum blood collection tube (EDTA tube) for laboratory analysis. If fluid cannot be recovered during an abdominocentesis, a diagnostic peritoneal lavage (stomach wash) can be done.
