Feline Urinary Tract Diseases: How to Prevent Them?

Stones, infections, kidney failure: urinary diseases are among the most common pathologies in cats. The good news is that a large proportion of them can be effectively prevented.

Why are cats particularly vulnerable to urinary diseases?

Cats are descendants of desert felines, accustomed to getting most of their hydration from their prey. Their bodies are designed to produce highly concentrated urine while consuming little water. This mechanism, perfectly adapted to wild life, becomes problematic in domestic cats fed kibble: overly concentrated urine promotes the formation of crystals, stones, and irritation of the urinary tract.

Males are even more exposed than females due to their narrower urethra, which becomes blocked more easily in case of stones. A urinary obstruction in a male cat is a veterinary emergency.

The most common urinary diseases in cats

Cystitis and urinary infections

Cystitis is an inflammation of the bladder, often without an identifiable bacterial infection in cats. It manifests as frequent trips to the litter box, painful urination, blood in the urine, or slight incontinence. Stress is one of the main triggers in domestic cats.

Urinary stones

Stones are mineral deposits that form in the bladder or kidneys. The most common in cats are struvite stones, promoted by overly alkaline urine, and calcium oxalate stones, linked to a diet too rich in calcium. Insufficiently diluted urine is the main risk factor.

Chronic kidney disease

This is the most common kidney disease in older cats. The kidneys gradually deteriorate and no longer filter blood properly. It is often silent in its early stages and is mainly detected by blood tests. Once declared, it cannot be cured but can be slowed down with appropriate management.

Feline lower urinary tract disease (FLUTD)

This is a term that encompasses all disorders affecting the lower urinary tract of cats: cystitis, stones, obstruction, spasms. It affects approximately 1 to 3% of cats and is strongly associated with chronic dehydration and a sedentary lifestyle.

How to prevent urinary diseases in your cat?

Hydration: the most effective lever

This is the most important point. A well-hydrated cat produces urine dilute enough to naturally eliminate crystals and bacteria before they accumulate. The more your cat drinks, the less concentrated its urine is, and the lower the risk of stones and infections.

The problem is that cats naturally drink little and are not very attracted to stagnant water. A filtered water fountain reproduces the movement of running water, which stimulates the cat's drinking instinct. Studies show that cats with a fountain drink an average of two to three times more than those who only have access to a bowl.

If your cat has a history of urinary problems, the 3.2L spout fountain is particularly suitable: its large capacity ensures permanent access to fresh, filtered water, even in your absence. For an apartment with a single cat, the 2.2L compact fountain fulfills the same role in a more compact way.

Adapted diet

Diet plays a major role in a cat's urinary health. Incorporating a portion of wet food (pâtés, pouches) into the daily ration significantly increases water intake and reduces urine concentration. If your cat is exclusively on kibble, pay particular attention to ensuring it has access to fresh and appealing water at all times.

Some kibble ranges are formulated for urinary health, with an adjusted pH and controlled mineral content. Your veterinarian can guide you to the most suitable one for your cat's profile.

Reduce stress

Stress is a major trigger for cystitis in cats. Moving, a new member in the household, a change in routine: any disturbance can trigger a urinary episode in a sensitive cat. Make sure to offer it a stable environment, refuge areas, and sufficient mental and physical stimulation.

Proper litter box maintenance

A dirty litter box can discourage the cat from urinating regularly, which promotes urinary stasis and the formation of stones. Clean the litter box at least once a day and provide one litter box per cat plus an additional one in the household.

Regular veterinary visits

Kidney and urinary diseases often progress silently. An annual blood and urine test can detect early signs of kidney failure or a urinary abnormality before it worsens. This is particularly important from 7 years of age.

Warning signs to watch for

Symptom	Recommended action
Frequent trips to the litter box without urinating	Consult quickly, risk of obstruction
Blood in the urine	Consult a veterinarian
Urinating outside the litter box	Consult a veterinarian
Sudden excessive thirst	Monitor and consult if it persists
Loss of appetite and lethargy	Consult quickly

Prevention of urinary diseases primarily relies on two simple pillars: optimal hydration and an adapted diet. A filtered water fountain is the most accessible and effective investment to encourage your cat to drink enough daily.
