Feline Urological Syndrome (FUS) is a common problem that affects cats. Its exact cause is still unknown.

Diet, inadequate water intake, bacteria, viruses, and stress may all be involved. Four common disorders are often associated with FUS:

Cystitis— inflammation of the lining and wall of the urinary bladder.

Infections— blood or mucus associated with inflamed tissue is a perfect place for bacterial infections.

Urethral Blockage— crystallization of minerals and irritation of the lining of the bladder and urethra can plug up or block the urinary outflow tract. This blockage is life-threatening if not relieved.

Uremia— a life-threatening accumulation of poisonous wastes in the bloodstream. The lack of urination causes a full bladder and this prevents the kidneys from discharging wastes from the body. Unless the blockage is promptly removed, the cat will suffer a painful death. Straining to urinate, depression, weakness, vomiting, and collapse are the signs which, if not corrected, lead to coma and death.

Symptoms to look for:

• Straining to urinate
  
• Small amounts or no urine at all
  
• Failure to use a litter box
  
• Urinating in a sink or bath tub
  
• Blood in the urine

Since we do not know the exact cause of FUS, the treatment procedures may vary. Medication may help or minimize the problem, but some cases may require surgical or professionally applied procedures. In order to avoid FUS, be sure to provide plenty of fresh water, feed your cat a balanced diet, keep a clean litter box, and provide your pet with exercise.
