Causes Of Cat Urine Crystals


There are several root causes believed to contribute to the buildup of urine crystals and struvite stones in cats. According to Veterinary Centers of America, struvite stones can be caused by the bacteria associated with a urinary tract infection. These bacteria produce a chemical called urease, which can alter the urines acidity, leading to the accumulation of crystals and the formation of struvite stones.;

If there is no infection present, as Dr. Goldstein says, veterinarians dont always know why a cat develops urinary crystals or stones. Its thought that can lead to a higher concentration of minerals in urine, causing crystals to form. Cats have evolved as a species to get the majority of their water from live prey, but this is unrealistic for domestic cats, especially if theyre indoor-only and prefer dry food. If a cat is less inclined to drink water alongside their dry food, theres less water present in the body to flush out waste, leading to a buildup of toxins and potential health issues. ;

Why Do Some Cats Form Stones If Struvite Crystals Are Considered Normal

There are several things at play in this situation. The urine pH, the presence of proteins around which the crystals can cluster, and the amount of water in the urine are all critical considerations. All of these elements combine to produce urine that is supersaturated with struvite. In dogs, infection is required for the formation of a struvite bladder stone, while in cats, the condition was not needed in 95 percent of cases of struvite bladder stones

The mineral struvite is found in around 45 percent of feline uroliths, and the majority of feline struvite uroliths form in sterile urine, according to the American Urological Association.

Causes Of Struvite Crystals

According to VCA Hospitals, in some cats, struvite bladder stones form as a result of a urinary tract infection, but this is less common in cats than in dogs.;;In most cases however, cats develop struvite stones in the absence of an infection. In these cases, the exact cause is unknown. A number of different factors have been found to contribute to these stones, including the formation of concentrated urine, increased urine pH , and increased levels of magnesium and phosphorus within the urine.

An underlying cause for the development of struvite crystals is that many cats are reluctant to drink water from bowls. They’ve evolved over millennia;to get most of their moisture from prey. This, partnered with a diet of dry cat food, can lead to crystal development in the cat’s urine.

Types Of Struvite Stones

Crystals develop due to supersaturated urine and pH or urease producing bacteria. Stones can be sterile or infected. Infected stones are caused by bacteria that produce urease which increase the concentration of ammonia in the urine, alter pH and alter the change in the ionisation state of phosphorus.

Sterile stones are associated diets with increased levels of magnesium, phosphorus, calcium and chloride, accounting for 95% of struvite stones in cats. Factors that lead to the formation of struvite stones include the concentration of urine, pH, presence of proteins around which the crystals can aggregate and diets high in magnesium.

The Treatment Of Cystoscopy

A Cystoscope is used in this treatment and is less invasive. It is a long thin medical instrument that comes with a small-sized video camera attached to it. The instrument is inserted inside the cats bladder. However, this method is only meant for female cats as the urethra of the male cat is too small for the instrument to enter. The instrument has a stone basket meant for retrieving stones from the bladder. There are cases when the crystals inside the bladder get too big and so a laser called Lithotripsy is used to break the stone down into smaller pieces to pass through the urethra. The laser within the instrument is positioned in close contact with the stones, which are then dissolved and retrieved. There is an addition of extra expenses involved with this procedure as it requires the need for special equipment to carry out the treatment.

How Does Diet Play A Role

When it comes to helping prevent struvite crystals and stones in your cat and maintaining their urinary tract health, nutrition plays a significant role! Both diet and water consumption can play a role in your cats urinary health. Cats arent natural water drinkers. As theyve evolved over millions of years and derived most of their moisture from their prey, its common for cats today to not always drink enough water. This is important to understand because struvite stones tend to form in a concentrated urine. Therefore, it is important to encourage adequate fluid intake can help prevent mineral concentration in urine and discourage stone formation. Dry cat food provides your cat with very little moisture in their diet, so considering incorporating wet food can be a great way to increase your cats water consumption.

Will Struvite Bladder Stones Recur After Treatment


Cats who have developed struvite bladder stones are likely to experience a recurrence later in life, unless the conditions that led to the formation of stones can be corrected.

The most important step to preventing recurrence is to feed a prescription diet. These diets are specially formulated to create a urine environment that is less favorable for the formation of struvite bladder stones. In general, these diets decrease the urine pH and restrict the levels of magnesium, ammonium, and phosphorus in the urine.

“The most important step to preventing recurrence is to feed a prescription diet.”

Additionally, you will need to increase your cats water intake in order to make your cats urine less concentrated. In most cases, using the canned version of your cats prescription diet will keep the urine dilute. In some cases, you may need to take additional steps, such as adding a running water fountain to your home, offering flavored water , or adding additional water to canned food.

Your cat will require long-term, regular rechecks. This will allow your veterinarian to monitor your cats urine, in order to ensure that her urine characteristics remain within desired parameters. Regular monitoring will also allow future recurrence of bladder stones to be detected early, when treatment may be easier and more effective.

An Improved Understanding Of The Role Of Ph Magnesium And Phosphorus; Greater Knowledge Of Risk Factors; And More Dietary Options Have Changed How Struvite Stones Are Treated In Cats And Dogs

While struvite uroliths may in some cases require surgical intervention, the recommended standard of care by the American College of Veterinary Internal Medicine is medical dissolution with a therapeutic diet formulated to alter urine acidity and encourage water consumption.

Dietary dissolution of struvite stones is both effective and inexpensive. Therapeutic diets limit calculogenic compounds and acidify urine. That makes the urine a less welcoming environment for stone formation and dissolves stones that are present.

Concerns medical dissolution places pets at risk of urethral obstruction are not borne out by the literature, according to the ACVIM consensus statement, published in the Journal of Veterinary Internal Medicine in 2016.

Dietary management itself has changed as well. The shift from struvite-only dissolution or prevention diets to combination struvite dissolution/prevention and calcium oxalate prevention diets is the biggest change in management of these uroliths, says Cailin Heinze, VMD, Dipl. ACVN, assistant professor of nutrition at Cummings School of Veterinary Medicine at Tufts University.

Urinary Tract Disorders: Urolithiasis

How To Dissolve Struvite Crystals In Cats

Animal Factors

Uroliths may be composed of several different types of minerals; struvite and calcium oxalate occur most commonly in adult cats.42,121,210 In kittens, infection-induced struvite and urate uroliths occur most commonly. In young adults struvite uroliths are typically not associated with a bacterial urinary tract infection. In older cats infection-induced struvite and calcium oxalate occur more commonly.12 Uroliths occurring in the upper urinary tract are typically composed of calcium oxalate.141,151,237

Urolith formation is associated with varying underlying causes. Sterile struvite uroliths are associated with the feeding of meals versus ad libitum feeding, dry foods, increased carbohydrate, certain protein sources, and alkaluria.* Conditions necessary for the formation of struvite crystals and uroliths include sufficient concentration of the composite minerals and retention of the components in the urinary tract for sufficient time to allow crystallization. Thus production of small volumes of concentrated urine would seem to be a contributing factor. In addition, a pH favorable for struvite precipitation must exist . However, many cats with struvite urolithiasis have a neutral or acidic urine pH at presentation.

Dietary Factors

The recommended dietary formulation for inducing dissolution of sterile struvite uroliths in cats is summarized in Box 18-12.79

Prevention of uroliths may involve dietary changes insofar as many types of feline uroliths are recurrent.

How To Dissolve Struvite Crystals In Cats

When you discover how to prevent struvite crystals in cats, you open a pandoras box. You discover new ways to keep your cat healthy, not just by preventing or getting rid of struvite crystals.

Struvite crystals are the most common form of mineral crystals that form in a cats urinary tract. Around half of all urinary stones in cats are struvite crystals.

You may be alerted to this problem when you see your cat straining to urinate, urinating outside the litter box, urinating frequently, has an increased thirst and/or has cloudy or bloody urine. The latter can only be seen if they urinate on a solid surface or a pale coloured fabric.

If you take your cat to the vet, you will almost always be given antibiotics and a speciality diet.

It is likely that neither will help the problem, because the cause was not addressed.

Struvite crystals in cats are formed when the urine pH is too high, ie too alkaline. Healthy cats have low pH urine, ie acidic.

So how do cats get urine that is too alkaline?

This means the antibiotics you are given, along with the speciality diet, which is inevitably high in plant based foods, will only exacerbate the problem, rather than help it.

Antibiotics kill off all bacteria, creating a digestion problem. The speciality diet is likely to be high in plant based food, so is a sideways move.

So what sort of diet will prevent struvite crystals in cats? Or dogs, for that matter. Or any health issue, as the right diet is key to good health in anyone.
