* bloody urine
* straining to urinate (can easily be mistaken for straining to defecate)
* urinating in inappropriate/unusual places
* urinary blockage (almost exclusively a male cat problem and constitutes an emergency)
* licking the urinary opening (usually due to pain).
The average age of a cat with FLUTD is 4 years. Of all cats with FLUTD:
* 50% will not have a cause that can be identified despite extensive testing.
* 20% will have bladder stones.
* 20% will have a urethral blockage.
* 1-5% will have a true infection.
* 1-5% will have a urinary tract cancer.
* 1-5% will have had trauma to the urinary tract (i.e., have been hit by a car etc.)
* 1-5% will have a combination of a bladder stone and an infection.
Hundreds of studies have been conducted to determine which causes are most likely for which cats. What has emerged from these studies is that for young adult cats, a definitive cause for the syndrome we call FLUTD cannot usually be found. These cats are said to have feline idiopathic cystitis or FIC, which means bladder inflammation of unknown cause.
Features of FIC:
* Lower urinary tract signs tend to recur.
* There seems to be an association with environmental stress.
* FIC seems to be a younger cat problem, with episodes decreasing in frequency as the cat gets older.
* Urinary crystals, previously believed to be central to the syndrome, seem to be involved only peripherally.
* Numerous therapies have been used to curtail the episode once it has started but because the episode seems to last a week or two regardless of treatment, it is hard to be sure what is working.
* As difficult as it is to address an episode in progress, more success has been achieved in preventing future episodes.
Why Do only some Cats get FIC?
We know that cats that get this syndrome have a unique imbalance in the way their brain controls hormones. In other words, these cats are unusually sensitive to environmental stress and, due to a complicated cascade of metabolic events, stress manifests in the urinary tract.
There are two parts of therapy: treating the episode and preventing future episodes.
Treatment of the Non-Obstructed Cat
Treating the Defective Mucous Lining- One theory says that the PSGAGs that line the bladder wall become patchy from abrasive crystals and abnormal pH, leading to tissue exposure and inflammation. Treating with PSGAG (Adequan) injections is aimed at helping restore this barrier.
* Increasing water intake
- The best way to increase water intake is to feed canned food since it is 80% water. Also, offering clean sources of water or getting a drinking fountain can encourage cats to drink. Increased water intake helps dilute the urine, which leads to less inflammation and fewer episodes. This is the #1 treatment for prevention of FIC
* Decreasing stress
- Environmental enrichment (toys, activities, interaction, scratching

- Decrease stressful interactions with other animals (own food/water dishes)
- Feliway pheromone plug in dispensers
- Appropriate number of litter boxes (# of cats plus 1 minimum)
- Anti-anxiety medications (amitriptyline, clomipramine, fluoxetine)
* Decreasing chronic inflammation
- Glucosamine supplements (Dasuquin) are thought to decrease some of the inflammation associated with FIC.
