🐾 What Is Peritonitis?
Peritonitis is the inflammation of the peritoneum, a thin, protective membrane that lines the abdominal cavity and surrounds internal organs such as the liver, stomach, and intestines. When this delicate tissue becomes inflamed, it can cause severe pain and lead to life-threatening complications if left untreated.
⚠️ Common Causes
Several conditions can trigger peritonitis in cats, including:
- Infections: Bacterial infections or viral diseases such as FIP (Feline Infectious Peritonitis) are common causes, especially in younger cats.
- Abdominal injury or trauma: From accidents, surgeries, or internal wounds.
- Organ rupture: Such as a torn bladder or punctured intestines, causing internal leakage of waste material.
🩺 Symptoms to Watch For
If your cat is showing any of these signs, seek veterinary help immediately:
- Loss of appetite or rapid weight loss
- Swollen, tender abdomen
- Vomiting or diarrhea
- Shallow, rapid breathing
- Lethargy or reluctance to move

🔬 Diagnosis
A veterinarian may perform a combination of:
- Blood tests
- Abdominal X-rays or ultrasound
- Abdominocentesis (drawing fluid from the abdomen to test for infection)

💉 Treatment Options
Treatment depends on the underlying cause and severity of the inflammation:
- Antibiotics for bacterial infections
- Supportive care such as IV fluids and pain relief
- Emergency surgery in cases involving organ damage or internal leaks
🛡️ Prevention Tips
- Keep your cat indoors to reduce exposure to infectious agents
- Ensure routine vaccinations, especially against FIP
- Maintain a clean environment and avoid feeding spoiled or dangerous items
