urinary cat food

Feline lower urinary tract disease (FLUTD) is pretty common in cats, and when treating it, the diet you provide is essential. This article describes what FLUTD is before discussing what to look for in a cat food for urinary care. 

We’ll then review our selection for the eight best cat foods for urinary tract health in 2021, which are:

What Is Feline Lower Urinary Tract Disease?

Feline lower urinary tract disease (FLUTD) is the collective name given to multiple causes of bladder and urethra issues in cats. These include urine infections, feline idiopathic cystitis, urolithiasis (urinary stones), and urethral obstruction.


During urination, urine travels from the bladder, where it is stored, and passes through the urethra before exiting the body.

If the bladder or urethra becomes obstructed or infected, urination can be difficult for your cat. Felines with FLUTD may exhibit some of the following symptoms:

  • Frequent urination.
  • Blood in the urine.
  • Urinating where they shouldn’t.
  • Straining when trying to urinate.
  • Meowing in pain when urinating.
  • Cleaning their urethral opening more frequently.

Call your veterinarian immediately if your cat displays any of these symptoms. If left untreated, FLUTD can progress to kidney failure—potentially fatal for your furry friend.

Risk Factors

FLUTD can present itself in cats of any age, although it’s more prominent in mature, overweight felines. Males also seem to be more predisposed than females. Other risk factors include lack of exercise, using a litter box, and no outdoor access. Environmental or emotional stressors can also pose a risk.

Diagnosis and Treatment

FLUTD can be difficult to diagnose because there are multiple reasons for it. Firstly your vet will assess your cat’s urine pH and carry out a physical examination. The assessment of your feline’s urine will show if there’s any bleeding, inflammation, infection, or urinary crystals. If they’re still unsure what’s causing the issue they may perform further urine tests along with blood tests, cultures, or x-rays.

How FLUTD is treated will depend on what the cause of it is. Increasing your cat’s water intake is always a good place to start. A vet may also advise you to place your feline on a specialized diet if they find crystals in the urine. These diets should help dissolve the crystals and prevent future stones and blockages. 

Struvite crystals are the most common form of crystal found in cat urine. These form from the minerals magnesium, ammonium, and phosphate, and they thrive in alkaline urine. Calcium oxalate crystals aren’t as common as struvite; they form in more acidic urine.

What to Look For in a Urinary Care Cat Food

When looking for food to improve our feline’s urinary health, we want it to do several things.

  • Increase water intake-A wet diet will contain high moisture levels. In contrast, a dry diet will sometimes contain added dietary sodium to encourage your cat to drink more. It is advisable to add water to dry kibble or supplement with wet food.
  • Decrease mineral intake-Urinary crystals such as struvite and calcium oxalate form when minerals combine in urine. Limiting your cat’s mineral intake helps prevent crystals and blockages from forming.
  • Control urine pH-A healthy urine pH level for a cat ranges between 6.3 and 6.6. Any pH lower than this range creates more acidic urine; anything above causes the urine to become more alkaline. Calcium oxalate crystals form in acidic conditions, and struvite crystals may develop in alkaline states. There are different foods available depending on which crystals are present in your cat’s urine.
  • Decrease protein intake-Your feline’s kidneys work hard to get rid of the waste created by protein. Less protein means less strain on their kidneys which preserves kidney function.
  • Added supplements-Supplements are things like vitamins and minerals, as well as antioxidants, fatty acids, and probiotics. Manufacturers add extra supplements to their urinary tract diets to alleviate anxiety symptoms and to support overall health.

Which food is best for a cat with urinary problems, dry or wet?

Either a wet or dry diet is fine, but consider this before deciding what’s best for your feline. When a cat suffers from urinary tract issues, it must be kept hydrated to flush out its bladder. Cats are not big drinkers, so increasing water intake is best done through their food. 

The easiest way to do this is by feeding them a wet diet that consists of approximately 75 percent water. On the other hand, kibble contains between five and ten percent water. It’s advisable to supplement a dry diet with canned food or add water to the kibble.

How can I increase my cat’s water intake?

Besides feeding your cat with wet food or adding water to kibble, there are a few other things you could try. Cat’s adore flowing water, so installing a drinking fountain for pets is a great idea. 

Another way is to try dishes that differ in size and shape then place them in different areas around the house. Cats can be fussy creatures, and you may find they prefer a specific dish or a particular location.

Can my cat still get FLUTD on a urinary care diet?

Yes, other risk factors contribute to FLUTD, such as lack of exercise and environmental stressors. When a cat is suffering from FLUTD, it is crucial to provide a holistic plan of action. Changing their diet won’t be sufficient if other factors are contributing to the problem.

Final Verdict

When trying to fight urinary issues, the best action is to make sure your cat is well hydrated. For this reason, wet food is an obvious choice when picking our winner.

It’s highly hydrating to encourage frequent urination and goes perfectly with Hill’s c/d if your cat’s a kibble lover. Unfortunately, you will need a prescription for this food.
