Previously addressed as FUS or feline urologic syndrome, FLUTD or the Feline Lower Urinary Tract Disease isnโ€™t a typical disease but a medical condition which occurs in the bladder or urethra, the lower urinary tract in cats. Causes of FLUTD are very difficult to underline although a majority of cats suffer from this disease.

Signs of FLUTD

Generally, cats suffering from FLUTD will also undergo the following signs. Dysuria is the medical condition where cats go through difficulty in the smooth passing of urine, often causing irritation and severe pain. Pollakiuria- this disease inflames the urinary bladder or the urethra causing irritation and enhancing the need to piss more often.


- sometimes, infection in the urinary bladder may cause blood to pass through urine.


- it is when cats urinate outside the litter box in unsuitable places. Due to inflammation or infection in the bladder, the cat feels irritated and unable to control the urine and is compelled to urinate at other places when the litter box is out of its reach


- the blockage in the urethra is known as Stranguria where cats feel the urgent need to urinate but are unable to do so. Male cats are more prone to this disease as their urethras are longer and narrower.

Cats vulnerable to FLUTD

Research has shown that FLUTD affects 1-3% of cats each year. Due to a diverse range of causes cats of any age, gender or breed can fall prey to this disease.

Causes of FLUTD

Some of the common causes of FLUTD are as follows.

  • Urolithiasis- this refers to the formation of bladder stones, which is one of the most common causes of FLUTD
  • Infections- bacterial infection of the bladder or cystitis is cited as one of the most common causes of FLUTD where the lower
  • urinary tract of felines are infectedUrethral plugs- this happens when there is an obstruction in the urethra of male cats due to the accumulation of organic debris like proteins, cells or minerals.
Treatment of FLUTD

If there are infections in the bladder, antibiotics are administered which relieves the cat of the disease. In the case of urethral obstructions, a catheter is passed through the urethra which relieves the obstruction. Sometimes bladder stones have to be surgically removed in cats to treat FLUTD. In other cases, therapy is provided as an alternative to surgery. There should be an increase in water consumption. Cats are encouraged to have plenty of fresh water and canned food as canned food contains more moisture content. Litter boxes should be washed and cleaned properly every time after use so that that cat may not catch infections.
