Which Is Better for General Urinary Health? Urinary Care Is the Best for Maintenance 💧

If your cat has a history of urinary issues but doesn’t currently have stones or crystals, Royal Canin Urinary Care is a better option for general urinary health maintenance. It’s formulated to promote a healthy urinary environment by preventing the formation of crystals without being too restrictive.

1. Royal Canin Urinary Care: This diet is designed for cats who are prone to urinary discomfort but don’t need the intense treatment offered by a prescription formula. Urinary Care helps maintain the proper balance of minerals in your cat’s urine to prevent the formation of struvite and calcium oxalate crystals. It’s suitable for long-term feeding and helps support bladder health in cats with mild urinary issues.
2. Royal Canin Urinary S/O: Urinary S/O is specifically designed to dissolve struvite stones and prevent the formation of both struvite and calcium oxalate stones. It’s a therapeutic diet, meaning it’s typically prescribed for cats with existing urinary issues, especially those who have had crystals or stones diagnosed by a vet. Urinary S/O works by increasing the water content in urine and reducing the concentration of minerals that form stones.

Product	Best For	Why It’s Beneficial	💡 Tip
Royal Canin Urinary Care	General urinary health maintenance for cats prone to mild urinary issues.	Helps balance minerals in the urine to prevent crystal formation.	Great for long-term use in healthy cats with urinary sensitivities.
Royal Canin Urinary S/O	Cats with existing crystals or stones who need active treatment.	Dissolves struvite stones and prevents both types of stones.	Best used under veterinary supervision for specific urinary conditions.

💡 Pro Tip: If your cat has had urinary issues but doesn’t currently have stones, Urinary Care is a safer and more balanced option for long-term management. Urinary S/O is best used for active treatment under your vet’s guidance.

Is Urinary S/O a Prescription Diet? Yes, Urinary S/O Requires Veterinary Guidance 🏥

One of the key differences between Royal Canin Urinary Care and Royal Canin Urinary S/O is that Urinary S/O is a prescription-only diet, meaning you’ll need a vet to prescribe it. This is because it’s formulated to treat specific urinary issues, like struvite stones, and has a more controlled nutrient profile than over-the-counter diets.

1. Why Urinary S/O Needs a Prescription: Urinary S/O contains higher levels of sodium and other ingredients that promote increased water intake and dilution of urine, which helps dissolve crystals and stones. While this is beneficial for treating urinary stones, it’s not ideal for healthy cats who don’t need these specific modifications. This is why it’s used as a short-term solution under the supervision of a vet.
2. Urinary Care Is Over-the-Counter: On the other hand, Royal Canin Urinary Care is available without a prescription. It’s suitable for cats who are prone to urinary issues but don’t currently have any serious conditions like stones. Urinary Care offers a balanced formula that gently supports urinary health without the intense effects of therapeutic diets.

Product	Prescription Required?	Why It’s Necessary	💡 Tip
Royal Canin Urinary Care	No	Designed for general maintenance of urinary health without the need for vet supervision.	Best for cats prone to urinary issues but without an active medical condition.
Royal Canin Urinary S/O	Yes	Therapeutic formula that treats existing stones and crystals.	Always consult your vet before starting Urinary S/O. It’s best for short-term, targeted use.

💡 Pro Tip: If your cat is already being treated for urinary crystals or stones, you’ll need a vet to prescribe Urinary S/O. For long-term urinary maintenance, Urinary Care can be purchased without a prescription and used for ongoing support.

Can Both Diets Prevent Crystals? Yes, But Urinary S/O Is More Effective for Dissolving Existing Stones 🔬

Both Royal Canin Urinary Care and Urinary S/O are formulated to prevent the formation of urinary crystals, but Urinary S/O goes a step further by dissolving existing struvite stones.

1. Urinary S/O’s Dissolving Power: Urinary S/O is designed to not only prevent crystals but to dissolve struvite stones that are already present. This makes it a powerful tool for cats who are actively struggling with struvite crystals or stones. Its formula works by making the urine more dilute and acidic, which helps to break down the crystals and stones.
2. Urinary Care for Prevention: Urinary Care is better suited for cats who are prone to crystal formation but do not currently have stones or severe urinary issues. Its formula promotes a balanced mineral content in the urine, preventing the development of both struvite and calcium oxalate crystals.

Product	Dissolving Existing Crystals?	Preventing Crystal Formation?	💡 Tip
Royal Canin Urinary Care	No	Yes – helps prevent both struvite and calcium oxalate crystals from forming.	Best for preventive care in cats with no current stones.
Royal Canin Urinary S/O	Yes	Yes – actively dissolves struvite stones and prevents further crystal formation.	Ideal for dissolving stones and short-term treatment.

💡 Pro Tip: If your cat is currently dealing with struvite stones, Urinary S/O is the better option as it will actively dissolve the stones. For cats that are healthy but prone to crystals, Urinary Care is more suited for long-term prevention.

Which One Is Safer for Long-Term Feeding? Urinary Care Is Ideal for Continuous Use 🕒

While both diets are beneficial for urinary health, Royal Canin Urinary Care is better suited for long-term feeding. Urinary S/O, due to its specialized formulation, is typically recommended for short-term therapeutic use unless your vet advises otherwise.

1. Urinary Care for Ongoing Maintenance: Urinary Care is a balanced diet that can be fed to your cat indefinitely. It’s designed to maintain optimal urinary health without drastically altering the mineral content of your cat’s urine. This makes it ideal for cats who are prone to urinary issues but don’t require therapeutic intervention.
2. Urinary S/O’s Limited Use: Urinary S/O is more restrictive in terms of long-term feeding. Its higher levels of sodium and specific formulation to dissolve stones make it a therapeutic diet rather than a daily maintenance diet. Your vet may advise using it for a few months to dissolve stones, after which you’ll transition to a maintenance diet like Urinary Care or another recommended food.

Product	Safe for Long-Term Feeding?	Best For	💡 Tip
Royal Canin Urinary Care	Yes	Preventive care for urinary sensitivities in healthy cats.	Best for cats needing ongoing urinary support.
Royal Canin Urinary S/O	No (short-term use recommended unless otherwise advised by a vet).	Dissolving stones and treating active urinary issues.	Use Urinary S/O short-term and transition to Urinary Care once stones are resolved.

💡 Pro Tip: For long-term urinary health, Urinary Care is a safe and balanced option for everyday feeding. Urinary S/O should be used as a temporary solution to treat active urinary conditions, and your vet may recommend transitioning to another food once the condition is under control.

Comment 1: “My cat just had struvite crystals, and the vet recommended Royal Canin Urinary S/O. How long should I keep my cat on this diet, and can I switch to Urinary Care afterward?”

Answer: Your vet’s recommendation of Royal Canin Urinary S/O is spot on for treating struvite crystals. This diet is specially formulated to dissolve existing struvite stones and prevent further formation. However, it’s important to use this therapeutic diet for the right amount of time and transition carefully based on your cat’s needs.

1. Duration of Use: Most cats with struvite crystals are kept on Urinary S/O for 2 to 6 months, depending on the severity of the crystals and your cat’s overall health. During this time, Urinary S/O works by increasing the water content in your cat’s urine and adjusting the pH balance to help dissolve the stones. Your vet will likely recommend follow-up tests, such as urine analysis or X-rays, to ensure the crystals have dissolved before making any dietary changes.
2. Switching to Urinary Care: Once the crystals are fully dissolved, you can discuss with your vet the possibility of switching to Royal Canin Urinary Care for long-term prevention. Urinary Care is less restrictive than Urinary S/O and is designed to maintain urinary health in cats that are prone to developing crystals but don’t need the intense therapeutic effects of S/O. The switch is generally recommended to prevent future recurrences while offering a more balanced, everyday diet.
3. The Transition Process: If you decide to transition from Urinary S/O to Urinary Care, it’s crucial to do it gradually. Cats have sensitive digestive systems, so switching foods too quickly can lead to gastrointestinal upset. Start by mixing 25% Urinary Care with 75% Urinary S/O, and slowly increase the ratio of Urinary Care over 7 to 10 days. This will allow your cat’s system to adjust without any disruptions in their digestive or urinary health.

Step	Action	Why It’s Important	💡 Tip
2-6 months on Urinary S/O	Keep your cat on Urinary S/O until the crystals have fully dissolved.	Helps dissolve existing struvite crystals.	Follow up with your vet to monitor your cat’s progress and ensure stones are fully dissolved.
Transition to Urinary Care	Slowly transition to Urinary Care once your vet gives the green light.	Provides long-term urinary health maintenance.	Mix the two diets gradually over 7-10 days to avoid digestive issues.

💡 Pro Tip: Stick to Urinary S/O until your vet confirms that the crystals are dissolved. Afterward, Urinary Care is a great long-term option for maintaining urinary health and preventing the recurrence of crystals.

Comment 2: “My cat had urinary stones but is prone to bladder inflammation too. Will Urinary S/O help with both stones and inflammation, or should I consider something else?”

Answer: Urinary S/O is highly effective in treating urinary stones, but it also plays an important role in reducing bladder inflammation. Here’s how it works and what you should consider if your cat is prone to both issues:

1. Urinary S/O for Stones and Inflammation: Urinary S/O not only helps dissolve struvite stones, but it also creates an environment in the bladder that reduces overall inflammation. Cats with FLUTD (Feline Lower Urinary Tract Disease) often experience both crystals and bladder inflammation, and the higher water content in Urinary S/O helps dilute the urine. This dilution reduces the concentration of minerals and irritants in the bladder, leading to less inflammation and fewer pain episodes.
2. How It Reduces Inflammation: The diet promotes a neutral pH balance in the urine, which prevents the formation of crystals while also making the urine less irritating to the bladder lining. If inflammation is caused by stress-related cystitis (a common issue in cats), your vet may also recommend behavioral changes or medications alongside the diet to manage stress and further reduce inflammation.
3. Long-Term Solutions: If your cat’s bladder inflammation is chronic, using Urinary S/O in the short-term can help tackle immediate issues related to stones and inflammation. However, for long-term maintenance, you may want to switch to a less intense diet like Royal Canin Urinary Care, which will still support bladder health and prevent inflammation but is better suited for daily feeding.

Issue	How Urinary S/O Helps	What to Consider	💡 Tip
Urinary stones and inflammation	Dissolves stones and reduces inflammation by diluting urine and balancing pH.	Effective for short-term use, but consider long-term options for chronic inflammation.	Keep your cat hydrated with wet food or water fountains to support bladder health beyond diet.

💡 Pro Tip: While Urinary S/O is great for treating both stones and inflammation, make sure your cat is also well-hydrated through wet food and increased water intake to prevent recurring bladder issues.

Comment 3: “I’ve been using Urinary Care for my cat, but I’ve heard that it doesn’t prevent all types of urinary stones. Should I be concerned?”

Answer: Royal Canin Urinary Care is designed to prevent urinary issues, including the formation of some crystals and stones, but it may not be as effective in preventing certain types of stones compared to Urinary S/O. Here’s what you need to know:

1. Urinary Care’s Focus on Prevention: Urinary Care helps maintain a healthy balance of minerals in the urine, reducing the risk of both struvite and calcium oxalate crystals. This makes it a great option for cats that are prone to recurring mild urinary issues but have not developed actual stones. The formulation encourages a good urinary environment without being overly restrictive, making it suitable for long-term feeding.
2. Urinary S/O’s Targeted Treatment: If your cat has a history of struvite stones or is at high risk for recurrent stone formation, Urinary S/O is the better option. Urinary Care may not be enough to dissolve or actively prevent certain types of crystals from forming. Urinary S/O specifically alters the pH balance and dilutes urine to break down stones—something Urinary Care isn’t formulated to do. While Urinary Care supports overall bladder health, it’s not a substitute for treating cats that need active stone prevention.
3. Should You Be Concerned? If your cat hasn’t had any significant issues with stones but is prone to occasional crystal formation, Urinary Care is likely sufficient. However, if your cat has a history of stones, or you’re noticing symptoms of urinary discomfort (frequent urination, straining, or blood in the urine), it’s worth consulting your vet to see if switching to Urinary S/O would be a more appropriate choice for preventing stone recurrence.

Product	What It Prevents	What It Doesn’t Do	💡 Tip
Royal Canin Urinary Care	Prevents struvite and calcium oxalate crystal formation.	Doesn’t dissolve existing stones.	Suitable for general urinary health and mild prevention, but consult your vet if stones are a concern.
Royal Canin Urinary S/O	Dissolves struvite stones and prevents both struvite and calcium oxalate stones.	More restrictive, not recommended for long-term use unless directed by a vet.	Best for cats with a history of stones or frequent urinary issues.

💡 Pro Tip: If you’re using Urinary Care and your cat hasn’t had issues with stones, it’s a great preventive option. However, if your cat develops stones, consider switching to Urinary S/O under your vet’s guidance to prevent recurrence.

Comment 4: “Can I feed both dry and wet versions of Urinary S/O, or is one better than the other?”

Answer: Feeding both dry and wet versions of Royal Canin Urinary S/O can be beneficial, depending on your cat’s needs and preferences. Here’s how each version works and why combining them might be a good strategy:

1. Wet Food for Hydration: The wet version of Urinary S/O offers a significant advantage by increasing your cat’s water intake, which is crucial for diluting urine and preventing crystal formation. Cats tend to have low thirst drives, so feeding wet food helps ensure they get the necessary hydration to flush their urinary systems more effectively. Wet food is especially helpful for cats prone to crystals and bladder inflammation, as more dilute urine reduces the concentration of minerals that form stones.
2. Dry Food for Convenience: Dry Urinary S/O is also effective in maintaining urinary health but without the hydration boost that comes with wet food. It’s convenient for feeding schedules or cats who prefer dry kibble. If you’re relying on dry food, make sure your cat has access to plenty of fresh water, possibly through a cat water fountain to encourage more drinking.
3. Combining Both: Feeding a mix of wet and dry Urinary S/O can offer the best of both worlds. You’ll get the hydration benefits of wet food and the convenience of dry food, especially if your cat prefers variety in their meals. Combining both types of food may also help increase your cat’s overall water consumption, which is critical for urinary tract health.

Food Type	Benefits	What to Consider	💡 Tip
Wet Urinary S/O	Increases water intake and helps dilute urine, reducing the risk of stones.	Can be more expensive and requires refrigeration once opened.	Best for cats prone to crystals and needing extra hydration.
Dry Urinary S/O	Convenient and easy to feed, provides all the same urinary benefits but without the hydration boost.	Ensure your cat drinks plenty of water if feeding dry food only.	Combining wet and dry can help balance hydration and convenience.

💡 Pro Tip: If your cat needs more hydration to support their urinary health, feeding a combination of wet and dry Urinary S/O is an excellent strategy. It ensures your cat gets enough water while still enjoying the convenience of dry kibble.
