what causes utis in cats

The most common organism to cause UTIs in cats is Escherichia coli (a bacteria found in feces), but there are many other possibilities. Sometimes there is more than one type of bacteria involved in the infection. The only way to identify which bacteria is involved is to grow it in a laboratory.

Urinary Tract Infection – Cat

While urinary tract problems are common in cats, urinary tract disease is more common in these furry friends than infections.

The majority of cats who experience urinary tract infections are 10 years of age or older, and they frequently also have endocrine conditions like hyperthyroidism and diabetes mellitus.

Your veterinarian will recommend an antibiotic to help treat your cat’s urinary tract infection (UTI) if it is determined that your cat has an infection like cystitis and is exhibiting symptoms of the condition (see below).

Urinating with difficulty, passing blood-tinged urine, reducing the amount of urine produced, not urinating at all, pain or discomfort during urination, and urinating outside of the litter box are the most typical signs of urinary tract infections in cats.

Your cat may have a urinary tract infection (UTI) if they exhibit any of the symptoms mentioned above, but they could also be signs of a feline lower urinary tract disease, or FLUTD.

What Causes Lower Urinary Tract Problems in Cats?

The veterinarian may ask you about your cat’s symptoms when you bring them in an effort to determine the exact cause of the issue. Urinary tract issues in cats can have a number of common causes, such as the following:

Urinary Tract Infection (UTI)

When there is a bacterial infection in the bladder or urethra, cats get UTIs. A urine sample is required by your veterinarian to diagnose this illness.

Uroliths (Urinary Stones)

Minerals found in urine can naturally aggregate and form small crystals or even large stones in your cat’s bladder. They may cause bloody urine, pain when urinating, and irritation of the bladder or urethra lining. Â.

Urinary stone diagnosis requires urine testing, X-rays, or ultrasounds performed by your veterinarian.

Urethral Obstruction

Your cat’s urethra may occasionally become totally obstructed by stones or a buildup of tissue and minerals known as a “urethral plug.” “Â.

This kind of obstruction prevents a cat from passing pee at all. Urinary tract obstructions are medical emergencies, so you should contact your veterinarian as soon as possible.

Feline Idiopathic Cystitis

On rare occasions, a cat’s lower urinary tract may become irritated without an infection or stones. Occasionally, it might be an indication of stress or a response to a dietary modification.

Other Causes

Other health conditions can affect cats urinary tract health. Diabetes and thyroid issues are sometimes to blame. In rare cases, cats get tumors in their urinary tract. To identify these conditions, your veterinarian will need to perform blood and urine tests.

Can Both Male and Female Cats Have Urinary Tract Problems?

All cats can get urinary tract problems. But male cats are more likely to have urethral obstructions. They have longer, thinner urethras than female cats. The smaller passage’s size and shape make it more likely to become blocked.


How did my indoor cat get a UTI?

Using an indoor litter box, emotional or environmental stress, multi-cat households or sudden changes to their everyday routine can also leave cats more vulnerable to urinary tract disease. If your kitty is diagnosed with FLUTD it is essential to determine the underlying cause.

What food causes UTI in cats?

Common reasons for UTI in felines: You are feeding a diet too high in digestible carbs/starch. Foods high in starch/carbs can create multiple health issues. Switch your cat to a carnivore-based diet. Research has shown that as the starch content of a diet increases your cats water consumption decreases.

Can litter cause UTI in cats?

Boxes should be cleaned on a regular basis, at least twice weekly, but sometimes daily changes are necessary. Unclean litter boxes can make cats more susceptible to developing urinary tract infections (UTIs).
