Feline Urinary Obstruction, Block cat:
Feline FUS
Feline Urologic Syndrome ‘FUS’ or cat Urinary Obstruction 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’.

The first sign of a urinary obstruction is straining to urinate. This may actually look like constipation since the cat may be seen going to the litter pan more often and hunching over in pain. Because of the abnormal passage of urine, the stream or flow of urine will be interrupted and may appear cloudy or bloody.
The pain involved causes many cats to cry out and they will stop eating and become depressed. Vomiting or retching may also occur if the early urinary obstruction signs passed unnoticed. If the cat does not receive medical treatment, renal failure can develop, which can be life threatening within three days of symptoms.

Cats that are blocked often show the following signs:
  • Repeatedly visiting the litter box (noting or few drops of urine produced often mistaken for constipation)
  • Straining
  • Crying or howling
  • Licking at the genitals
  • Hiding
  • Painful abdomen
  • Vomiting

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.
