Sterile cystitis, also known as Pandora Syndrome, Feline Interstitial Cystitis, or Feline Idiopathic Cystitis (FIC), is a condition in cats characterized by inflammation of the urinary bladder wall, leading to various clinical signs. Unlike bacterial cystitis caused by infections or cystitis due to bladder stones, sterile cystitis has no obvious cause, even after investigation. It predominantly affects young to middle-aged cats, with symptoms often recurring episodically.
Symptoms of Sterile Cystitis
- Bloody urine
- Straining during urination
- Painful urination
- Urinating outside the litter box
- Increased urinary frequency
- Frequent genital licking
- Inability to urinate despite attempts (a veterinary emergency)
Diagnosis and Evaluation
- Physical Examination: Conducted by a veterinarian.
- Diagnostic Tests: Typically include complete urinalysis, X-rays, and possibly abdominal ultrasound. A complete blood count (CBC) and chemistry panel may also be performed. Testing rules out other causes of urinary tract issues.
- Additional Stress Factors: Chronic early stress in a cat's life can change gene expression, making them more susceptible to diseases like sterile cystitis. Cats experiencing sterile cystitis often show abnormal hormonal responses to stressors.
Management and Treatment
- Veterinary Diets: Specialized diets can help prevent blockages in male cats, which can be caused by mucus-protein mixtures. These diets promote more dilute urine and may contain fatty acids to reduce inflammation.
- Behavioral Modification: A program known as Multimodal Environmental Modification (MEMO) aims to reduce stress factors. MEMO involves creating safe spaces, ensuring food and water satisfaction, providing suitable litter boxes, encouraging play, and resolving conflicts in a cat's environment.
- Medications: While there is no specific drug for sterile cystitis, medications can be prescribed to manage pain, straining, and anxiety during active bouts of the disease.
Prognosis and Management
- Recurring Episodes: Many cats with sterile cystitis will cycle in and out of active phases, often triggered by stress. MEMO helps manage these episodes and reduces their frequency. It's unlikely to completely eliminate symptoms, but the goal is to make episodes less common and less severe.
- Individualized Approach: MEMO isn't a one-size-fits-all solution. Tailor the approach to your cat's specific stressors. Regular communication with your veterinarian is crucial to refine the strategy and make adjustments based on your cat's responses.
