Spotting the signs and symptoms of urinary tract infections in cats reading-time-icon 2 min read

Feline urinary tract disease ( otherwise known as FLUTD) is a painful condition in both male and female cats that can go on to damage the kidneys if left untreated.  Feline urinary tract disease can be tricky to identify, so we look at the signs and symptoms to look out for in your cat. In fact most cats with these symptoms do not have a urinary infection but nonetheless you should see your vet to make sure your cat receives the right care.

Signs of urinary tract infections in cats

It’s not unusual for cats with urinary tract infections to display no symptoms – which makes feline urinary tract disease (FLUTD) hard to spot. You may notice your cat using the litter tray more often than usual, but only passing a small amount of urine each time.

You may spot small amounts of blood in your cat’s urine, or find that they stop using the litter tray altogether. Cats are clever creatures, and once they begin to associate the litter tray with pain, they’ll understandably be reluctant to use it. It’s quite possible that this will be the first sign of FLUTD in your cat.

If you notice any of these changes in your cat’s behaviour, get them to your local vet for a full check-up.

Occasionally, crystals or stones plug the cat’s urethra and they can’t wee at all – this problem is most common in young adult male cats who, understandably, can become agitated and uncomfortable as a result. If this occurs, seek veterinary advice immediately for emergency help.

Signs and symptoms of FLUTD in cats

  • Unusually frequent attempts to wee, that produce small amounts of urine
  • Blood in the urine
  • Difficulty urinating (dysuria)
  • Weeing outside the litter tray
  • Cloudy urine
  • Fever
  • Lethargy or listlessness

Cats at increased risk of FLUTD

As with any infection, elderly cats and those with a weakened immune system are most at risk of developing a urinary tract disease. Both stress and long-term steroid use can weaken the immune system, increasing a cat’s chances of developing FLUTD. Indoor cats are at particular risk but there are things you can try to reduce this.
