Urinary blockage, also known as feline lower urinary tract disease (FLUTD), is a common and potentially life-threatening condition in which a cat is unable to urinate, particularly in males.

Cats are typically fastidious about their potty habits—so if you’ve noticed a change in how much they’re using the litter box, consider it a red flag. How much a cat pees can vary, depending on how much they drink, the type of food they eat, their activity level and their health status.

But while some variation in the amount of urine a cat produces is normal, big changes—like if you think your cat is not peeing much at all—can indicate serious health risks.Here’s an overview of its predisposition, causes, signs and symptoms, treatment, and prevention:

Cat unable to urinate; Predisposition:

  1. Male Cats: Male cats, especially those that are neutered and middle-aged, are more predisposed to urinary blockages due to their narrower urethra.
  2. Certain Breeds: Some breeds, such as Siamese and Himalayan cats, have a higher predisposition to urinary tract issues.
  3. Dietary Factors: Diets high in magnesium and phosphorus or low in moisture content can contribute to urinary tract problems.
  4. Lack of Exercise: Sedentary lifestyles can increase the risk of obesity, which is linked to urinary issues.

Cat unable to urinate;Causes:

  1. Crystals or Stones: Crystals or stones (like struvite or calcium oxalate) can form in the bladder, causing blockages.
  2. Mucus or Debris: Build-up of mucus or debris in the urinary tract can obstruct urine flow.
  3. Inflammation: Inflammation of the bladder (cystitis) or urethra can lead to swelling and blockage.
  4. Stress: Stress can exacerbate urinary issues in susceptible cats.
  5. Urinary Tract Infections (UTIs): Bacterial infections can cause inflammation and blockages.
  6. Anatomical Abnormalities: Rarely, structural abnormalities in the urinary tract can predispose a cat to blockages.

Signs and Symptoms:

  1. Straining to Urinate: Frequent trips to the litter box with little to no urine produced.
  2. Pain or Discomfort: Vocalization, restlessness, or signs of pain while urinating.
  3. Blood in Urine: Urine may appear bloody or discolored.
  4. Licking Genital Area: Excessive grooming of the genital area due to discomfort.
  5. Urinary Accidents: Urinating outside the litter box, as cats may associate the litter box with pain.
  6. Lethargy: Lack of energy or enthusiasm for usual activities.


  1. Emergency Veterinary Care: Immediate veterinary attention is necessary to relieve the blockage and prevent life-threatening complications.
  2. Urinary Catheterization: Passage of a catheter to remove the blockage and allow urine to flow freely.
  3. Fluid Therapy: Intravenous fluids to correct dehydration and restore electrolyte balance.
  4. Pain Management: Pain medications to alleviate discomfort.
  5. Antibiotics: If a urinary tract infection is present, antibiotics may be prescribed.
  6. Dietary Changes: Prescription diets formulated to dissolve stones or crystals and prevent their formation.
  7. Monitoring and Follow-up: Regular check-ups to monitor urinary health and address any recurrent issues.


  1. Hydration: Encourage adequate water intake by providing fresh water sources and wet food.
  2. Balanced Diet: Feed a balanced diet formulated to maintain urinary health, possibly under the guidance of a veterinarian.
  3. Stress Reduction: Minimize stressors in the cat’s environment through environmental enrichment and routine.
  4. Litter Box Management: Maintain clean litter boxes and provide multiple boxes in multi-cat households.
  5. Regular Veterinary Visits: Schedule routine check-ups to monitor urinary health and address any emerging issues promptly.

Prompt recognition and treatment of urinary blockages are crucial for ensuring the well-being of affected cats. If you suspect your cat is experiencing urinary issues, seek veterinary attention immediately.
