Feline Incontinence: Why Is My Cat Leaking Urine?

Cats are meticulously clean animals, so any health problem that leaves them feeling wet or dirty is particularly distressing. Urinary incontinence is the inability to control the bladder due to age, illness, or obstruction. The impairment results in the cat leaking urine involuntarily.

Incontinence is not to be confused with behaviorally inappropriate urination in which cats intentionally pee outside their litter box.

What to do if your cat is leaking urine:

1. See your vet as soon as possible.

As soon as you notice any of the above symptoms, schedule a visit with your vet. He or she will perform a thorough physical exam and will likely recommend diagnostic tests such as bloodwork, X-rays, and/or ultrasound. 

2. Start treatment.

Depending on the diagnosis, your vet will determine a treatment plan that may or may not include medications. For example, if your cat is leaking urine due to a urinary tract infection, he or she will prescribe antibiotics. Older cats and those suffering urinary incontinence due to a hormone imbalance may require hormone replacement therapy.

In more serious cases, surgery may be necessary to repair a spinal cord injury or remove a urinary tract obstruction.

3. If your cat is obese, begin a weight loss program.

Obesity often contributes to feline incontinence by applying excess pressure on the bladder. It is also a risk factor for diabetes, kidney failure, and kidney stones, all of which cause cats to drink more water and urinate more frequently.

Additional tips for caring for an incontinent cat:

  • Place extra litter boxes for senior cats and those with decreased mobility.
  • Use pet diapers at bedtime.
  • Clean your cat’s urinary area with cat-safe soap or wipes to prevent urine scald.
  • Ask your vet or groomer to give your cat a “potty patch” or hygienic cut to reduce mess.
