Feline Urologic Syndrome ‘FUS’ is a common syndrome in male cats, it is known in veterinary parlance as a ‘blocked tom’ or ‘blocked cat’. Urethra of male cats is narrow at the penile part particularly close to the tip. Any sediment, mucous, or stones coming from the urinary bladder passing through the urethra could block the penile urethra.
If the flow of urine stops, waste products such as Blood Urea Nitrogen, Creatinine, Potassium  build up in the blood stream causing azotemia and hyperkalemia (increase potassium in the blood). It is known in veterinary parlance as a ‘blocked tom’ or ‘blocked cat’.

Cats that are blocked often show the following signs:
•\tRepeatedly visiting the litter box (noting or few drops of urine produced often mistaken for constipation)
•\tStraining
•\tCrying or howling
•\tLicking at the genitals
•\tHiding
•\tPainful abdomen
•\tVomiting

If you notice your cat showing any of the above signs, get right in to see an emergency veterinary services. Don’t wait as a few hours can make a big difference. Cats with urinary obstruction require immediate urinary catheterization to release the urine, any delay can result in kidney damage or death.
The course after unblocking these cats is just as unpredictable. Some cats are released from the hospital never to suffer another episode, while others will have repeated urinary obstructions in days, weeks, or years later.
