What are urinary tract infections (UTI) in cats?

Content by Dr Nicole Olewinski – BVSc MRCVS

Urinary tract infections (UTIs) in cats occur when bacteria enter the urinary tract, usually by travelling up the urethra into the bladder.

Despite being well-known, UTIs are actually uncommon in cats. Studies suggest only a small percentage of cats will develop a true bacterial infection during their lifetime. Many cats with urinary symptoms actually have other conditions instead, which is why accurate diagnosis is important.

Overview
  • Uncommon cause of urinary signs in cats
  • Seen more often in older female cats
  • Often linked to underlying health conditions
  • Can be acute or recurrent
  • Requires testing to distinguish from other urinary diseases
What Causes What Causes
What causes UTI in cats?

Urinary tract infections in cats are usually caused by bacteria. These bacteria often come from the naturally occurring populations at the entrance to the urogenital tract or from the gut. Most cats that develop a UTI have an underlying issue that gives these bacteria an opportunity to cause an infection.

Urine is naturally antibacterial, and regular urination helps flush the bladder. However, inflammation, blood, glucose in diabetic cats, or very dilute urine can reduce these natural defences – making it easier for bacteria to grow. Cats that hold their urine for long periods rather than going regularly to the litter tray may also be at increased risk.

What Causes What Causes
Which breeds are most affected?

Any breed can develop a urinary tract infection, but it is more commonly seen in older female cats. Any cat that struggles to groom itself effectively due to a long coat, obesity, arthritis or digestive issues will have a higher risk of developing a UTI. Some studies suggest Abyssinians and Persians may be at slightly higher risk. 

Cats with underlying conditions such as chronic kidney disease, diabetes or hyperthyroidism are also more susceptible to urinary tract infections.

What Causes What Causes
What are the signs and symptoms of a mild to moderate UTI?

Some cats may have bacteria in their urine without obvious signs. However, common symptoms include:

  • Repeated trips to the litter tray
  • Straining to urinate
  • Licking the genital area
  • Urinating in unusual places (eg sinks, baths, laundry)
  • Blood-tinged (pink) urine

Diagnosis

Urine dipsticks can provide a quick indication of changes within the urine, but they can sometimes give misleading results in animals. For greater accuracy, vets will often spin down a urine sample and examine the sediment under a microscope to check for bacteria, inflammatory cells or crystals.

To ensure the most effective antibiotic is used, a urine culture and sensitivity test may be recommended. This helps avoid delays caused by using antibiotics that the bacteria are resistant to.

What Causes What Causes
Treatment of mild to moderate UTI

Once a UTI is confirmed, treatment typically involves antibiotics. If there is significant inflammation or discomfort, anti-inflammatories and pain relief may also be prescribed.

Management of underlying risk factors is just as important. This may include dietary changes, supplements, weight management, or support with grooming to reduce the chance of recurrence.

Prognosis

With mild infections, many cats improve within a few days and make a full recovery within a week.

What Causes What Causes
What are the signs and symptoms of severe or recurrent UTIs?

In some cases, infections can be more severe, recur frequently, or spread beyond the bladder. Cats may show more obvious discomfort, including vocalising when urinating, producing very small amounts of urine, or having visibly bloody urine. They may also become generally unwell, with reduced appetite, vomiting, or lethargy.

While UTIs themselves are uncommon, any urinary tract disease in male cats can lead to a blocked bladder, a life-threatening emergency that requires immediate veterinary attention.

Diagnosis

In more severe cases, the same urine tests will be performed. However, additional investigations such as blood samples, ultrasound or X-rays will be recommended to look for underlying conditions or complications.

What Causes What Causes
Treatment of severe UTI

More severe infections often require a longer course of antibiotics, ideally guided by urine culture results. Hospitalisation may be needed if the kidneys are affected or if an underlying condition – such as diabetes – requires stabilisation.

If the bladder becomes blocked – which is more likely in male cats – emergency treatment is needed to relieve the obstruction, empty the bladder and support the kidneys.

Prognosis

When cats have severe or recurrent issues, prognosis depends on any underlying conditions and whether complications – such as kidney involvement – are present. Long-term medication and management plans are often needed in these cases.

Our expert says...

“If your cat develops urinary signs, don’t be surprised if your vet recommends more than just a short course of antibiotics.

“We know from experience that urinary problems in cats can be frustrating and sometimes serious, but they are rarely ‘just’ an infection. When bacteria are identified, we immediately start thinking about why the body’s natural defence mechanisms have failed. This means looking for underlying causes.

“You can help get the ball rolling by collecting a urine sample at home: the fresher, the better. Empty your cat’s litter tray, rinse and dry it, then either leave it empty or use non-absorbent beads from a testing kit, and wait.

“You’ll likely be advised to go ahead with additional tests. But rest assured, this isn’t to complicate things. It’s to reduce the chances of you spending even more of your time in the consulting room when the problems come straight back.”

Frequently asked questions

  • What are the symptoms of a UTI in cats?

    Straining to urinate, frequent trips to the litter tray, and urinating in unusual places are common signs. You may also notice licking of the genital area, or blood in the urine.

  • How is a UTI diagnosed?

    Diagnosis involves testing a urine sample. This may include examining it under a microscope and performing a bacterial culture to confirm infection and guide antibiotic choice.

  • Can UTIs become serious?

    Yes, especially if they spread to the kidneys or occur alongside other health problems. Cats that become lethargic, stop eating or struggle to urinate need urgent veterinary attention.

  • Are UTIs common in older cats?

    UTIs are more likely in older cats, particularly females. And when they do occur, there is often an underlying condition such as kidney disease or diabetes.

  • Can stress cause UTIs?

    Stress is a common cause of feline idiopathic cystitis, which can lead to an infection, but stress is unlikely to cause a primary urinary infection.
