Has your cat been going outside of her litter box? Perhaps you’ve come home to discover that she peed on the rug or your bed. One of the main causes of inappropriate urination is feline idiopathic cystitis (FIC). To discover if your cat is missing the box because of this urinary condition, read on to learn about the disease signs, diagnosis, and treatment.

Feline idiopathic cystitis signs

FIC can develop without any obvious underlying cause, and more than one unidentified, underlying condition that leads to FIC is possible. Cats with FIC will show signs that indicate an issue with their lower urinary tract system, including:

  • Urinating outside the litter box or in unusual places
  • Increased irritation or aggression
  • Painful or difficult urination
  • Frequent urination
  • Blood in the urine
  • Overgrooming because of bladder pain

If you notice your cat struggling to urinate, contact us immediately. Male cats—and occasionally female cats—can develop a life-threatening urinary blockage.

Feline idiopathic cystitis diagnosis

Since no diagnostic test can confirm that your cat is suffering from FIC, the diagnosis is made by ruling out other potential urinary conditions. To do that, we will examine a urine sample for the presence of red, white, and abnormal blood cells, bacteria, or crystals, and take X-rays to rule out urinary tract stones and bladder masses. An ultrasound of the entire urinary tract may also be indicated. Blood work is necessary to check kidney function and to search for other potential causes of urinary issues.

Feline idiopathic cystitis treatment

With no definitive cause of FIC, treatment is challenging and focuses on encouraging frequent drinking and urination, reducing stress, and stimulating your pet mentally. Management measures include:

  • Offering more drinking stations throughout your home
  • Providing a drinking fountain instead of a water dish
  • Switching from dry to canned food to increase water intake
  • Investigating prescription urinary diets
  • Adding more litter boxes in various quiet places in your home
  • Reducing stress by:
    • Playing with your cat daily
    • Offering scratching posts and climbing towers
    • Creating elevated perches for napping and observing
    • Avoiding household inter-cat conflict
    • Diffusing the Feliway pheromone in areas where your cat spends most of her time
    • Allowing daily outdoor activity in an enclosed run to provide mental stimulation
