The right diet is crucial for managing feline bladder stones. The cornerstone of treating and preventing bladder stones is feeding your cat a specially formulated diet that helps dissolve existing stones or prevent new ones from forming, and that is low in the minerals that contribute to their formation.

Understanding Feline Bladder Stones

Bladder stones, also known as uroliths, are mineral formations that develop in a cat’s bladder. These stones can cause significant discomfort, pain, and even life-threatening urinary blockages, particularly in male cats. Understanding the different types of bladder stones and their causes is essential for determining the appropriate dietary management.

The most common types of bladder stones in cats are:

Struvite stones: These are often associated with urinary tract infections (UTIs) and alkaline urine.
Calcium oxalate stones: These stones are not related to UTIs and form in acidic urine.
Urate stones: These stones are less common and associated with liver disease.
Cystine stones: A rare stone due to metabolic problems.

The pH of your cat’s urine plays a significant role in stone formation. Struvite stones thrive in alkaline urine, while calcium oxalate stones favor acidic urine. Diet plays a key role in influencing urine pH.

The Role of Diet in Managing Bladder Stones

Dietary management is the primary strategy for dissolving struvite stones and preventing recurrence of both struvite and calcium oxalate stones. What can I feed my cat with bladder stones? The answer depends on the type of stones present and your veterinarian’s recommendations.

A therapeutic diet designed for bladder stone management typically has the following characteristics:

Controlled Mineral Levels: These diets contain reduced levels of minerals like magnesium, phosphorus, and calcium, which are building blocks for struvite and calcium oxalate stones.
Urine pH Control: Special ingredients help maintain an optimal urine pH, making it less favorable for stone formation. Struvite diets acidify the urine, while diets for calcium oxalate stones are usually designed to maintain a neutral pH.
Increased Water Intake: Many therapeutic diets are formulated to encourage increased water consumption, either through higher sodium content or by being available as wet food. Increased water intake dilutes the urine, reducing mineral concentration and flushing out the bladder.
Specific Protein Levels: The protein content is carefully balanced to promote urine acidity or alkalinity, depending on the type of stone being managed.

Choosing the Right Food: Wet vs. Dry

Both wet and dry food options are available for managing bladder stones. Wet food is generally preferred because of its higher water content.

Here’s a comparison:

Feature	Wet Food	Dry Food
————–	————————————–	—————————————–
Water Content	High (70-80%)	Low (6-10%)
Mineral Levels	Typically controlled	Typically controlled
Palatability	Generally more palatable for cats	Convenient and cost-effective
Urine Output	Increased, promoting stone dissolution	Potentially lower, requires encouraging water intake

If you choose dry food, it’s essential to encourage your cat to drink more water. Provide multiple fresh water sources, consider using a water fountain, and offer flavored water or low-sodium broth.

Common Mistakes to Avoid

Feeding over-the-counter cat food: These foods are often not formulated to address bladder stone issues and may even exacerbate the problem.
Supplementing with minerals: Avoid giving mineral supplements unless specifically directed by your veterinarian.
Changing the diet abruptly: Introduce new foods gradually to avoid digestive upset.
Ignoring your veterinarian’s advice: Always follow your veterinarian’s recommendations regarding diet and treatment.
Giving treats without considering their impact: Many treats are high in minerals and can counteract the benefits of the therapeutic diet. Check with your veterinarian about appropriate treats.
Failing to provide fresh water. This is crucial, regardless of the type of food.

Monitoring and Follow-Up

Regular veterinary checkups are crucial for monitoring your cat’s progress. Your veterinarian may recommend:

Urine analysis: To monitor urine pH and mineral levels.
Radiographs (X-rays) or ultrasound: To assess the size and number of stones.
Blood tests: To evaluate kidney function and overall health.

What can I feed my cat with bladder stones? Remember that consistent adherence to the prescribed diet is vital for successful management.

Other Considerations

While diet is a crucial element, it’s not the only factor in managing bladder stones. Other considerations include:

Treating underlying infections: If a UTI is present, it must be treated with antibiotics.
Encouraging urination: Provide a clean and accessible litter box.
Weight management: Obesity can increase the risk of bladder stones.
Stress reduction: Stress can contribute to urinary problems in cats.

Frequently Asked Questions (FAQs)

What is the best food to dissolve struvite bladder stones in my cat?

The best food for dissolving struvite stones is a prescription diet formulated to acidify the urine and be low in magnesium, ammonium, and phosphate. These diets are specifically designed to break down struvite crystals and stones effectively. Hill’s Prescription Diet s/d and Royal Canin Urinary S/O are common options.

Can I feed my cat a homemade diet for bladder stones?

While it might seem appealing, homemade diets for bladder stones are generally not recommended unless formulated by a veterinary nutritionist. It’s extremely difficult to balance the necessary nutrients and maintain the correct urine pH without specialized knowledge and testing. An unbalanced homemade diet can lead to further health problems.

How long will it take for a special diet to dissolve my cat’s bladder stones?

The time it takes to dissolve bladder stones varies depending on the size and type of stones, as well as your cat’s individual response to the diet. Struvite stones typically dissolve within a few weeks to a few months with the appropriate diet. Your veterinarian will monitor your cat’s progress and adjust the treatment plan as needed.

Is it okay to give my cat treats while they are on a special diet for bladder stones?

Giving treats to a cat on a special diet for bladder stones can undermine the effectiveness of the diet. Many treats are high in minerals that can contribute to stone formation. Discuss appropriate treat options with your veterinarian. Some specially formulated urinary treats may be acceptable in small quantities.

Will a urinary diet prevent all types of bladder stones?

No, urinary diets are formulated to address specific types of bladder stones. A diet designed for struvite stones, for example, may not be suitable for calcium oxalate stones, and could even worsen the condition. It’s crucial to determine the type of stones your cat has before selecting a diet.

What happens if my cat refuses to eat the prescription diet?

If your cat is refusing to eat the prescription diet, try warming the food slightly to enhance its aroma. You can also try mixing a small amount of the new food with your cat’s old food, gradually increasing the proportion of the new food over several days. If your cat still refuses to eat, consult with your veterinarian, who can offer alternative food options or strategies to encourage eating. Do not starve your cat into eating the diet, as this can lead to hepatic lipidosis (fatty liver disease).

How often should I take my cat to the vet for checkups while they are being treated for bladder stones?

The frequency of veterinary checkups depends on the severity of your cat’s condition and your veterinarian’s recommendations. Typically, checkups are recommended every few weeks during the initial phase of treatment to monitor urine pH, mineral levels, and stone size. Once the stones have dissolved or are being managed effectively, checkups may be reduced to every few months.

Can stress contribute to the formation of bladder stones in cats?

Yes, stress can contribute to the formation of bladder stones in cats. Stress can lead to inflammation in the bladder, which can increase the risk of struvite stone formation. Providing a stable and enriching environment for your cat can help reduce stress levels and support urinary health.

Is it possible for bladder stones to come back even after being treated with a special diet?

Yes, bladder stones can recur even after successful treatment. Regular monitoring and adherence to the prescribed diet are essential for preventing recurrence. Your veterinarian may recommend long-term dietary management and periodic urine testing to ensure that the urine pH and mineral levels remain within the optimal range.

Are male cats more prone to bladder stones than female cats?

Male cats are more prone to life-threatening urinary blockages caused by bladder stones due to their narrower urethra. However, both male and female cats can develop bladder stones.

Can I give my cat supplements to help prevent bladder stones?

In general, it’s not recommended to give your cat supplements without consulting your veterinarian. Some supplements may contain minerals that can contribute to stone formation. Always follow your veterinarian’s recommendations regarding dietary management and supplements.

What else can I do to help my cat with bladder stones besides diet?

In addition to diet, encouraging water consumption is crucial. Provide multiple fresh water sources, consider using a water fountain, and offer wet food. Maintain a clean and accessible litter box to encourage frequent urination. Minimize stress in your cat’s environment. And adhere to all veterinary recommendations for medication and follow-up care.
