As cat owners, we all know our feline friends are experts at hiding pain. Unfortunately, that means serious health problems can go unnoticed until they become emergencies.

One of the most common urinary conditions we treat in cats is Feline Lower Urinary Tract Disease (FLUTD). While some cases are mild, others can become life-threatening — especially if a cat is unable to pass urine.

Knowing what to look for could save your cat's life.

What is FLUTD?

Feline Lower Urinary Tract Disease (FLUTD) is a term used to describe conditions affecting a cat's bladder and urethra — the tube that carries urine out of the body.

There are several possible causes. Some cats develop bladder stones or bacterial infections, while others experience inflammation without an obvious underlying cause. This is known as Feline Idiopathic Cystitis (FIC) and is often associated with stress.

Regardless of the cause, FLUTD can be painful and should never be ignored.

Signs your cat may have FLUTD

Cats often show subtle signs before their condition becomes severe. Contact your veterinarian if you notice your cat:

What causes FLUTD?

FLUTD isn't a single disease — it can be caused by several different conditions, including:

How is FLUTD diagnosed?

Because the symptoms of FLUTD can have different underlying causes, your veterinarian may recommend several diagnostic tests, including urine analysis, blood tests, x-rays, and ultrasound. These tests help determine whether your cat has an infection, bladder stones, crystals, inflammation, or a urinary blockage, allowing the most appropriate treatment plan to be developed.

Treatment options

Treatment depends entirely on the underlying cause. Some cats improve with pain relief, anti-inflammatory medication, prescription urinary diets, and increased water intake. Others may require antibiotics, hospitalisation, intravenous fluids, emergency treatment to relieve a urinary blockage, or surgery in more complex cases.

It's also important to know that FLUTD can recur, so ongoing management is often recommended to reduce future flare-ups.

Can FLUTD be prevented?

While FLUTD can't always be prevented, there are several ways to reduce your cat's risk.

Early treatment can save lives

Because cats naturally hide pain, urinary problems can progress quickly before owners realise something is wrong. If you notice any changes in your cat's urination — even if they seem minor — it's always worth having them checked by a veterinarian. Early diagnosis often leads to simpler treatment and better outcomes.

If your cat is straining to urinate, producing very little urine, or seems uncomfortable when using the litter tray, don't delay seeking veterinary care.
