Product Information

Struvite Dissolution
Provides nutrition that aids in the management of pure struvite uroliths.

Urine Dilution
Increasing the urine volume simultaneously reduces the saturation of urine with calcium oxalate and struvite crystals.

Relative Super Saturation (RSS) methodology predicts the crystallization potential of urine; RSS is used to develop diets that lower the concentration of ions contributing to struvite and calcium oxalate urolithiasis.

Controlled Magnesium
Reduced level of magnesium, a natural component of struvite stones.

Rated 5 out of 5 by from It comes in cans! We feed our 2 cats the vet prescribed Royal We feed our 2 cats Royal Canin dry SO daily and use the canned version to supplement if we run out of dry food between purchases. We are very happy with the results! Our cat with the urinary problem has not been sick at all since starting this food. Both cats have a very healthy coat of fur and are mostly left alone when it comes to parasites. We live in a wooded area and expected to deal with fleas and tics. It has not been a problem even without the monthly meds. The food makes all the difference! We are thankful for Royal Canin and the research they have done to perfect their products.

Rated 5 out of 5 by from My Cat Loves this food. Four years ago my neutered male orange tabby developed a urinary tract infection that lead to his urinary track blocking after several weeks of infection. When he was being catheterized to remove the block, the veterinarian found that his urinary track actually had two 90 degree turns that were impossible to clear. He finally had to have a little done surgery that actually rerouted his urinary tract to his abdomen. After this surgery was done the veterinarian recommended Royal Canin canned Urinary SO. Since that time Sunnyshine has not had another urinary infection or any more blocking and now at 10 years old is a very happy, healthy kitty boy.

Rated 5 out of 5 by from Clean...simple design Elijah has been on this formula both moist and dry for the past 5 years. Since changing his diet his health has improved tremendously. Elijah is a ten year old recused cat that was totally feral at the time of rescue. My daughter worked with him and they both fell in love with each other. Since Elijah has been on your food his Ph balance has returned to normal and his UTIs are few and far between. When my husband was dying from Cancer Elijah became completely blocked and was rushed to the Vets...Dan made me promise to do anything to help Tif's cat. Using your product has helped me keep this promise. Thank you

Rated 5 out of 5 by from Life Saving! Last year I had to rush one of my cats to the emergency vet because he was unable to urinate and was growling and not acting like his normal wonderful self. It turned out he had crystals in his urine and was in a lot of pain. This was his first time ever having this issue come up. The vet took great care of him and he got medications to treat the problem. I followed up with my regular vet and he prescribed the Royal Canin Urinary SO food to keep this under control. He does SO well on it and now all four of our cats eat it for every meal. I’m so thankful for this food and it keeping my babies in great health.

Rated 4 out of 5 by from Happy Babies Every Day We have 4 of our 10 furry friends on the SO diet currently, and I must say that all enjoy their wet food each and every day without hesitation. You'd think after a time they would tire of the flavor as many do of other foods, but not so with this special Urinary diet. Others will even try to steal from their dishes, must be quite appetizing for them to snub their own food and go for the SO! It does its job and has kept all 4 free of any urinary issues for quite a few years already. Great product, please don't change a thing! Just wish the price would come down a bit more.

Rated 4 out of 5 by from It works! One of our three cats was having bladder stone issues so she (as well as the other two) was put on the Urinary SO dry & canned foods. Within a couple of weeks it was clear that her stones had dissolved which meant no surgery required!!! Have kept them on Urinary SO ever since (4 years now) and haven’t had any more issues. While it is a bit on the expensive side, it tends to be more filling than lesser brands so they seem to eat less. More importantly however, it is still far less costly than vet bills, or worse yet, surgery.

Rated 5 out of 5 by from LIFESAVER! Several years ago our male Russian Blue feline was diagnosed with a urinary problem and your Urinary SO products were recommended by our veterinarian. Today, he is 15 years of age and is in great health! A BIG PLUS for your Urinary SO dry food is that in addition to him eating it daily alongside his water dish, we also use it as his treat! We simply mix catnip flavored items in a sealed jar with your dry food, shake it up, and treat him only with your product! He begs us several times each day!!!

Rated 5 out of 5 by from Helps keep my male cat healthy! Our vet recommended this food for my male cat Jack after he had crystals in his urine and had to get surgery to remove a blockage. When we switched vets the new one had said that another cheaper food was just as good. Within 6 months he had another blockage from crystals. Needless to say we switched back to the old vet and the royal canin urniary SO food and have not had a blockage or crystals in his urine in 3 years now. Never trying another food!!
