A Cat's Guide to Royal Canin Veterinary Diet Feline Urinary S/O Dry Cat Food

If a domesticated cat could speak human, we might hear about their digestive care. Good thing that there are cat food brands that prioritize balanced nutrition, digestive healthcare, and dietary issues, specifically the Royal Canin Veterinary Diet that maintains a highly-digestible nutritional blend of pure protein, vitamins, and amino acids.

Since 1968, Royal Canin's veterinarians, pet nutritionists, breeders, and cat professionals formulated precise diets that guarantee specific nutritional requirements and a cat's special needs. Royal Canin prioritizes health cat nutrition with the highest standard of quality and safety in their cat chow products.

Why should your cat eat Royal Canin Veterinary Diet Feline Urinary S/O Dry Cat Food?

Urinary crystals are a primary factor in the development of bladder stones and may occur when there is a dietary mineral excess. Struvite is urinary stones made of magnesium, ammonium, and phosphates. Kidney stones, from struvite to calcium oxalate, tend to form in acidic urine.

Royal Canin Veterinary Diet Feline Urinary S/O Dry Cat Food makes a urinary environment that is unfavorable to the formation of kidney stones (e.g., struvite stones and calcium oxalate crystals):

  1. Relative Super Saturation (RSS) methodology lowers the risk of crystal formation
  2. Controls the levels of magnesium, calcium, and phosphates that are found in excess minerals that form crystals and stones
  3. Lowers the ion concentration to lessen the pH level of the cat's urine (less acid toward neutral pH levels)
  4. Enriched with antioxidants and omega-3 fatty acids in EPA and DHA

This exclusive and specialized blend nutritionally supports your adult cat's urinary tract and bladder health with the Royal Canin's exclusive S/O index to promote healthy urinary environments. It dissolves and prevents kidney stones and dilutes the excess minerals that can also form crystal and stones.

Nutritional Value

Royal Canin Veterinary Diet Feline Urinary S/O Dry Cat Food contains nutritional values in crude protein, fat, and fiber:

Crude Protein (32.5 %) is the measure of all sources of nitrogen and includes nonprotein nitrogen, which may have no human value. Crude protein is a chemical analysis of the protein (e.g., chicken, milk, etc.) and non-protein (e.g., grains) amounts in the food. The recipe's low crude protein is important to avoid overtaxing the kidneys.

Crude Fat (13.5 %) is the term for fat-soluble materials such as lipid content in your cat's food when ingested. The diet is restricted in fat.

Crude Fiber (4.5 %) is a measure of indigestible cellulose, pentosans, lignin, and other components of this type of chemical fibers. A highly digestible fibrous food boosts the healthy absorption of essential vitamins and minerals. It provides major intestinal tract peristalsis, a wave-like muscle contraction to relax the stomach muscles.

Is Royal Canin urinary so good for cats?

Yes, the Royal Canin Urinary SO dry cat food is good for cats.

The feed was produced as a nutritional product for cats with urinary health problems. This canned cat food has the capability to adequately support your cat's urinary tract and bladder. Royal Canin helps increase the amount of urine your cat produces. Larger quantities of urine expelled help dilute excess minerals that can form crystals or stones. Hence, the feed helps to keep the cat's urinary tract and bladder healthy.

Can any cat eat Royal Canin urinary so?

Yes, any cat can eat Royal Canin Urinary SO; even the healthy ones.

The Urinary SO was developed to nutritionally support cats that require urinary care. It is used as a food item as well as medication and is recommended to cats suffering from urinary health issues by licensed vets. Although it is safe to feed urinary food to a healthy cat, you should still consult with your vet before giving a healthy cat Urinary SO.

However, cats with special conditions should avoid the Royal Canin and other urinary cat feed. These include

  • Very young kittens.
  • Cats that are pregnant or nursing.
  • Cats taking urinary acidifying medication
  • Cats with kidney and/or heart diseases/conditions.

What is comparable to Royal Canin urinary so cat food?

The Royal Canin Urinary SO + Calm, and the Royal Canin Urinary SO + Satiety are comparable to the regular Urinary SO cat food.

The SO + Calm and SO + Satiety are similar to the Urinary SO in a few ways. Firstly, all three of these cat feeds increase urine production in cats in a controlled way. Secondly, they all contain fatty acids as well as Omega-3. And finally, you can use all three of them for cats of all ages. They only differ in terms of ingredients, and that too is almost negligible. The SO + versions are for more complicated cases.

How does Royal Canin urinary so cat food work?

The Royal Canin Urinary SO cat food works by increasing the volume of urine produced in cats.

An increase in the amount of urine produced enables cats to expel or push out dilute minerals from their urinary tracts or bladders. These minerals, if stuck inside the tracts, can lead to the formation of crystals or stones, which can prove to be life-threatening for cats. Hence, the Royal Canin Urinary SO works by allowing cats to expel these minerals through an increased amount of urine produced.

Which is the best food for cats suffering from urinary tract issues?

The Royal Canin Urinary SO dry cat food is the best food for cats with urinary tract issues.

The Urinary SO is a cat feed that has been artificially enriched with necessary nutrients to increase urine production in cats. That in turn, makes it possible for them to fight off stones and excess minerals that might be present in their urinary tracts.

How long does it take for struvite crystals to dissolve in cats?

Struvite crystals take one to two months to dissolve in cats.

In most cases, an increased amount of urine produced in cats helps prevent struvite stones or crystals. They expel the excess minerals through the urine which in turn stops the formation of these crystals. However, in some cases, this method might not work. You might require surgery to physically remove the crystals from the tract.

What ingredient in cat food causes crystals in urine?

Minerals, like magnesium, calcium, and phosphorus, in cat food cause crystals in urine. Excess minerals that accumulate in the urinary tracts of cats over time lead to the formation of crystals.

Vets will ask you to avoid mineral-enriched cat feed if your cat is suffering from urinary health problems.

How much Royal Canin urinary should I feed my cat?

You can feed your cat anything from one-fourth of a cup to one and a half cups of Royal Canin Urinary SO.

The amount of feed you give depends on the size of your cats. The bigger or heavier they are, the more food they will need. The food is a good source of Vitamin E, B6, B12, B3, D1, zinc, folic acid, etc. One kilogram of Urinary SO contains 3,631 kcal, while a cup contains 298 kcal.

How long does Urinary cat food take to work?

Urinary SO takes only ten days to work. It does so by regulating the mineral balance in cats, by promoting a healthy increase in urine production.

Store the bag at room temperature, and keep the packaging out of the reach of pets and children.

On Day 3 and Day 4, mix 50% of the old diet with 50% of the new diet. On Day 5 and Day 6, mix 25% of the old diet with 75% of the new diet. On the 7th day, you can feed the new food exclusively. This allows your pet's digestive system to smoothly adapt to the new food.
