Urinary Disease In Cats | Managing Feline Lower Urinary Tract Disease

Various types of urinary and bladder problems affecting cats fall under the veterinary heading of feline lower urinary tract disease. If you notice Kitty having difficulty urinating, take her to a veterinarian as soon as possible. The worst case scenario is a blockage of urine, a life-threatening situation.

Cat disease of the lower urinary tract

Formerly known as feline urological syndrome or FUS, feline lower urinary tract disease covers all problems with the kidneys, bladder, ureter – the tubes that send urine from the kidneys to the bladder – or to the urethra, dealing with the ability to urinate.

While kidney failure is common in older cats, the symptoms and treatment are completely different. Cats with kidney failure usually urinate too much, not too little. Causes of FLUTD trigger a gamut, from infection to cancer.


Cats suffering from cystitis are not blocked or completely unable to urinate, but their urethra are inflamed and urination is painful. Your veterinarian diagnoses cystitis by analyzing the urine, looking at the pH of the urine and what type of crystal appears.

Kitty can receive medication to reduce inflammation, along with antibiotics, while your veterinarian recommends dietary changes to prevent recurrence.

Urinary stones

Cat bladder stones usually consist of either struvite or calcium oxalate materials. To make a diagnosis, an X-ray of your vet or an ultrasound of Kitty’s bladder. The treatment depends on the type of stone and how it affects Kitty. Struvite stones eventually fall apart with a special diet.

This does not apply to calcium oxalate stones. Your veterinarian is likely to perform a cystotomy or stone removal operation. In some cats, your veterinarian may be able to flush the juices from calcium oxalate because the female cat’s urethra is wider than the male’s urea.


No matter what type of FLUTD your cat is eventually diagnosed with, the symptoms are very similar. You’ll see Kitty come in and out of his trash and try to pee. He licks his private homes to alleviate discomfort. The urine could contain the blood it produces, or it could start having urinary “accidents” all over the house.

If he is blocked, he could start screaming in pain. Regardless of the actual diagnosis, FLUTD is a potentially fatal condition. Take Kitty to the vet as soon as possible.


Cats that experience one episode of FLUTD can do it again, so it’s a nightmare you want to prevent. Your veterinarian may recommend a special prescription diet for Kitty. Because stress can be a factor in FLUTD episodes, try to keep Kitty’s routine regular and provide a calm life situation. Keep litter boxes extremely clean and secure at least one litter box for the household. Make sure Kitty always has access to clean, fresh water. Keep it healthy.
