Cat Urinary Tract Infection & Treatment

Cat urinary tract infections are much more rare than urinary tract infections in dogs, nonetheless, cats (particularly senior cats) do frequently experience other urinary tract issues. Here our Mooresville vets share the symptoms, causes and treatments for urinary tract infections and diseases in cats.

Urinary Tract Infections (UTI) in Cats

While urinary tract issues are often seen in cats, our feline friends are more prone to urinary tract disease than infections. Those cats that do develop urinary tract infections often suffer from endocrine diseases, such as hyperthyroidism and diabetes mellitus, and are typically 10 years of age or older.

If your kitty is displaying symptoms of a urinary tract infection (see below) and is diagnosed with an infection such as cystitis your veterinarian will prescribe an antibacterial to help fight your cat's UTI.

The most common symptoms of urinary tract infections in cats include straining to urinate, reduced amounts of urine, not urinating at all, pain or discomfort when urinating, passing urine tinged with blood (pink-ish color urine), and urinating around the house (outside of the litter box).

A urinary tract infection may indeed be the cause of your cat's symptoms however, there are also a number of feline lower urinary tract diseases (FLUTD) that could be causing your cat to display the UTI symptoms listed above. 

Feline Urinary Tract Disease (FLUTD)

FLUTD  (Feline lower urinary tract disease) is actually an umbrella term that refers to numerous clinical symptoms . FLUTD can cause issues in your cat’s urethra and bladder, often leading the urethra to become obstructed, or preventing your cat's bladder from emptying properly. These conditions can be serious or even life threatening if left untreated.

If your kitty is suffering from FLUTD, urinating can be difficult, painful or impossible. They may also urinate more frequently, or in inappropriate areas outside their litter box (occasionally on surfaces that are cool to the touch such as a tile floor or bathtub).

Causes of Feline Urinary Tract Disease

FLUTD is a complex condition to diagnose and treat since there are multiple causes and contributing factors to this disease. Crystals, stones or debris can gradually build up in your cat's urethra (the tube connecting the bladder to the outside of your cat’s body) or bladder.

Some other common causes of lower urinary tract issues in cats include:

  • Incontinence due to excessive water consumption or weak bladder
  • Spinal cord issues
  • Urethral plug caused by the accumulation of debris from urine
  • Bladder infection, inflammation, urinary tract infection (UTI)
  • Injury or tumor in the urinary tract
  • Congenital abnormalities
  • Emotional or environmental stressors

Urinary tract disease in cats is most often diagnosed in overweight, middle-aged cats who have little to no access to outdoors, eat a dry food diet or do not get enough physical activity, although cats of any age can get the condition. Male cats are also more prone to urinary diseases since their narrower urethras are more likely to become blocked. 

Using an indoor litter box, emotional or environmental stress, multi-cat households or sudden changes to their everyday routine can also leave cats more vulnerable to urinary tract disease.

If your kitty is diagnosed with FLUTD it is essential to determine the underlying cause. FLUTD symptoms can be caused by serious underlying health issues such as bladder stones or infection to cancer or a blockage.

If your veterinarian is unable to determine the cause of your cat's FLUTD, your kitty may be diagnosed with a urinary tract infection called cystitis which is inflammation of the bladder.

Symptoms of Feline Urinary Tract Disease in Cats

If you suspect your cat has FLUTD or a cat urinary tract infection, watch for the following symptoms:

  • Inability to urinate
  • Loss of bladder control
  • Urinating small amounts
  • Urinating more than usual or in inappropriate settings
  • Avoidance or fear of litter box
  • Strong ammonia odor in urine
  • Hard or distended abdomen
  • Cloudy or bloody urine
  • Drinking more water than usual
  • Excessive licking of genital area
  • Lethargy
  • Vomiting

It’s critical that any bladder or urinary issue be treated as early as possible. If left untreated, urinary issues in cats can cause the urethra to become partially or completely obstructed, which can prevent your feline friend from urinating.

The symptoms above indicate a serious medical issue that could quickly lead to kidney failure or rupture of the bladder. FLUTD can quickly be fatal if there is an obstruction that is not eliminated immediately.

Diagnosing Feline Urinary Tract Disease

If you believe that your feline friend may be having problems with their lower urinary tract, contact your vet right away, especially if your cat is straining to urinate or crying out in pain.

Your vet will perform a complete physical exam to help assess your cat's symptoms and perform a urinalysis to get further insight into your cat's condition. Ultrasound, radiographs, blood work and a urine culture may also need be done.

Treatment for Feline Urinary Tract Disease

Urinary issues in cats can be complex and serious, so the first step should be to visit your veterinarian for immediate care. The underlying cause of your cat's urinary symptoms will dictate which treatment is prescribed, but may include:

  • Increasing your kitty's water consumption
  • Antibiotics or medication to relieve symptoms
  • Modified diet
  • Expelling of small stones through urethra
  • Urinary acidifiers
  • Fluid therapy
  • Urinary catheter or surgery for male cats to remove urethral blocks
