Lower urinary tract disease (LUTD) refers to a group of disorders that commonly leads to irritation of the urinary tract and corresponding undesirable clinical signs. What causes Lower Urinary Tract Disease? In cats, bacterial infections are far less common. Urinary crystals and stones are often linked to this disease. The most common cause of Lower Urinary Tract Disease in cats is idiopathic cystitis.This diet promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals.

Key Benefits

  • Complete and balanced canned cat food diet recommended for cats at risk of developing lower urinary tract disease
  • This diet promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals.
  • Help prevent struvite, calcium oxalate and phosphate uroliths
  • 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
  • Increasing the urine volume simultaneously reduces the saturation of urine with calcium oxalate and struvite crystals

Royal Canin Veterinary Diet Urinary SO in Gel Canned Cat Food is rated 4.7 out of 5 by 346.
Rated 5 out of 5 by from 2 Cats for me with bladder issues Over one week 2 of my adult male cats both became very sick with stones and blockage. The urinary diet was suggested, and despite the cost this food has become a way of life for all three of my adult male rescue cats. As hard as it was to shell out the vast amounts of money each month, all cats are thriving on this food since Feb. 2016. What I really like besides my cats obvious enjoyment of this food, is that it is firm from the can, not disgusting to touch if some misses the dish. My boys eat the gel and the morsels, another Royal Canin urinary canned food. They lick their dish clean, then each other's. I serve the dry low calorie Royal Can in urinary food while I'm at work long days and they can't wait to get the canned meal before and after work. For all the love and joy they give to me, they deserve the extra cost. helps in a HUGE way with the autoship with convenience and price discounts. I never run out and have to pay the horrendous local higher prices. Click, it's here in 2 days. Try it, your cats will thank you.

Rated 5 out of 5 by from My cat depends on this wet food. My cat George is a senior girl, and she has to depend on Royal Canot in Veterinary Diet SO wet canned food to prevent urinary crystals so she can go pee. She really enjoys this food and can not tell the difference between this and regular wet cat food. I highly recommend it to everyone.

Rated 5 out of 5 by from Excellent, but pricey This is an excellent product for protecting against crystals in the urine. My cat (8 years old) had this problem and nearly died from it. I started using Royal Canin Urinary SO after this episode (based on the recommendation of our Vet) and my cat seems to be doing well. It is 6 months after and he is doing fine. Of course, he has a check-up next week, so we'll see how he's really doing. Unfortunately, this prescription food is much more expensive than regular cat food. If you have a male cat, you might want to try giving him canned food mixed with a little extra water (to make sure he gets a good amount of water in his diet). But, if he has urinary issues, just go to this Royal Canin canned food (which should be better than the dry, which we also give him - since there's a higher moisture content). Our cat also seems to like the food. This is a good product. I also give this to our 3 year old female cat, in addition to regular canned and dry food, and she enjoys it and seems to also be doing well.

Rated 5 out of 5 by from No Recurrence & Great Price My male cat has had 2 bladder stones thus far in his life. After the second one, we knew that something had to be done. The cost of surgery and the stress it involved for myself and my cat was simply not worth it anymore. Plus, since my cat simply does not want to drink water, we had to do wet food. Our vet originally recommended Science Hills but when we moved, our new vet only carried Royal Canin. Maybe it was a selling tactic, but our new vet also said some studies have shown Royal Canin has an even better prevention rate. So we went ahead and tried it. Of course the wet food versus dry has made a huge difference in his health overall and there has been no recurring bladder stones! While a case can be expensive, Chewy has it for even cheaper, on autoship, with quick shipping, and a discount. Also, our vet was completely fine with writing a prescription for it. Now there are no regrets about providing this for the long and healthy life of my cat. It really does work!

Rated 5 out of 5 by from Comparable prices and Free Shipping! One of my cats requires special food but I didn't like going to the big box store and lugging a month's supply home. I avoid all that mess, save time, a little bit of cash, and spare my back by having it delivered by CHEWY. Cases of canned cat food arrived quick, and were adequately packaged. No complaints. This is where I'll be getting cat food from now on.

Rated 5 out of 5 by from Loved by finicky eater! I have a young lynx point male with perpetual urinary & stomach issues that has to be on a restricted diet. My vet and I tried numerous different brands of the prescription canned foods and he refused to eat any of them. A co-worker came across a can of the Royal Canin Urinary SO (pate) so we gave that a try. He loves this food and gobbles it up every time! I would definitely recommend this food even for the non-finicky that are on food restrictions.

Rated 5 out of 5 by from This product appeals to all my cats.charlene I have a nine cat household and getting everyone to eat and enjoy the same food has always been a challenge......until now. Everyone loves it. It is very easy to portion out...moist & easy to eat. This is a great choice for cats with urinary problems and for older cats as well. I have both. I am an auto/repeat customer. Thank you so much. Charlene Woonsocket,RI.

Rated 5 out of 5 by from Royal Canin Vet Diet SO=So Far, So Good After taking my 11 year old female cat to the vet twice in six weeks for a UTI it was discovered "she" is actually a "he" and had crystals in his urine. The $$ spent for this enlightening info and treatment, steroids, antibiotics and muscle relaxants, and anti anxiety medication, was astronomical. I requested a second opinion and was advised by this Vet that my cat may do well with the Royal Canin Vet Diet SO and no meds. After being on this food for about three months there have been no recurrences of his urinary issue. My fingers remain crossed. I have noticed he, Lillimae, is drinking very little water, but urinating much more. Additionally he really enjoys the Royal Canin and waits patiently for his three, meals per day. His coat is also much shinier. Occasionally I add a tsp of either No Salt Added canned chicken or Low Low Sodium canned Tuna. I am very pleased with this product and will continue to order as needed. Yes it is expensive BUT much less than shelling out several thousand dollars during the year for vet bills.
