How to Treat and Prevent Cat Bladder Crystals

Bladder crystals form from minerals in your cat’s diet and can grow big enough to develop stones. It’s important to understand the signs that your cat may have urinary crystals to prevent unnecessary suffering. Diagnosis and treatment are straight-forward. Working with your veterinarian, you can provide your cat with a high quality of life. Surgery may not be necessary.

Depending on the kind of crystals your cat has developed, your cat’s diet can be manipulated to dissolve the stones. Changes to diet and water intake are key to preventing crystals and stones from forming again.


Symptoms

Recognizing the signs of bladder crystals is important to getting your cat the help he needs. Your cat may have bladder stones or crystals if he has the following symptoms:

  • Straining while urinating

  • Urinating often, but in small quantities

  • Urinating anywhere other than their litter box

  • Distressed behavior while urinating

  • Licking their genitals

  • Discolored urine, especially if it appears bloody

Some cats don’t show any signs of bladder crystals. This is just one reason why an annual exam is important.


Diagnosis

If you suspect your cat may have bladder crystals, take her to your veterinarian for proper diagnosis right away. Stones that have grown large enough may be felt through the abdominal wall. For proper diagnosis, your cat’s veterinarian will probably use a combination of urinalysis, ultrasound, or x-rays.

Diagnosis should include determining what kind of crystals have formed as treatment is different for the different types.


Treatment

There are a variety of ways to help your cat at home with the direction of your veterinarian. Diet adjustments can be made depending on what kind of crystals your cat has. The crystals may be dissolved by changing the pH levels of your cat’s urine.

For larger crystals, or in the case of an obstruction, surgery may be necessary to remove the crystals. With any kind of crystals it is important to increase your cat’s water intake. You can encourage this by providing fresh water at all times and switching to canned food instead of dry food.


Struvite Crystals

Struvite crystals are formed in more alkaline urine and are made up of ammonium, phosphate and magnesium. It is possible to dissolve the crystals through diet.

Your veterinarian may prescribe a diet to make your cat’s urine more acidic. Do not give your cat urine acidifiers if your cat is on a prescription diet.

You will also need to increase your cat’s water intake to help make the urine more dilute. This will help dissolve or flush the crystals and help prevent the formation of new ones.


Calcium Oxalate Crystals

Calcium oxalate crystals tend to form in more acidic urine. Unfortunately, there is no way to dissolve the stones through diet, so surgery or hydro propulsion may be necessary to remove the stones.

A diet designed to make your cat’s urine more alkaline can help to prevent the crystals from forming.

Like with struvite crystals, increasing your cat’s water intake is essential to treat and prevent crystals and stones from forming.


Urate Crystals

Urate crystals are more common in dogs but have been found in cats as well. A diet lower in protein may be prescribed by your veterinarian to balance the pH of your cat’s urine.

Due to its rarity, no formulated diet exists for cats with urate crystals. A diet lower in protein, and especially purines may be prescribed.

Again, increase your cat’s water intake to both help treat the crystals and prevent the from forming again.


Lifestyle Adjustments

If there are no complications requiring surgery, treatment for urinary crystals is easy and simple. Increase your cat’s water intake. And your veterinarian may prescribe a diet to balance the pH levels of your cat’s urine.


Change Diet

Working with your veterinarian to know which diet to feed your cat is crucial. Depending on the crystals your cat has, your cat may need adjustments to protein, calcium, magnesium, or phosphorus.

Increasing your cat’s water intake is also important. Switching your cat to a canned food diet instead of dry is an easy way to do this.

Running Water

Some cats love drinking from running water. But you don’t want to leave a tap running all the time. Investing in a water fountain for your cat is an excellent solution.

Complications

There are complications that can arise from bladder crystals. Any obstruction caused by a stone in the urinary tract is life-threatening for your cat.

Male cats are at greater risk of having an obstruction as the urethra is more narrow in males than in females.

The signs of an obstruction are:

  • Nausea and vomiting

  • Loss of appetite

  • A distended abdomen

If your cat exhibits symptoms of an obstruction, seek medical help right away.


Recurrence and Prevention

The best thing you can do to prevent bladder crystals from forming is to make sure your cat gets enough water in his diet. This makes the urine more dilute. It also decreases the amount of time urine stays in the bladder. This decreases the chances of crystals forming, regardless of pH levels.

Your cat may need to have checkups in addition to his annual exam to ensure that crystals are not forming again. Check with your veterinarian if you need to continue any prescribed diet.

Hard water may be linked to the formation of crystals as well. If you live in an area with hard water, investing in a pet fountain with a filter may be another method of prevention. Remember to change the filter regularly.
