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

  • Recommended for cats at risk of developing lower urinary tract disease
  • Dissolution of pure struvite uroliths
  • Help prevent struvite, calcium oxalate and phosphate uroliths
  • Provides nutrition that aids in the management of pure struvite 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
  • Reduced level of magnesium, a natural component of struvite stones

Rated 4.6 out of 5 by 290 reviewers.
Rated 5 out of 5 by royal canin vet so feline My Bella had bladder surgery. My Vet prescribed this food for her. She was eating Fancy Feast and Science diet dry. The transition went beautifully. She got used to this and the dry food, and canned morsels in gravey. The problem was me. I felt so bad for her that she couldn't eat her other food, but after talking to my Vet he assured me this was the only way to prevent a bladder stone. Transition over, she is now on this new food for 10 whole days and I do not ever want to see another bladder stone. I can say that the food helps her drink the water she needs. Her coat is beautiful. No more constipation and she passes tons of urine a few times a day.My Vet is one in a million, but I see a positive difference with the food. All you moms out there, it will be ok switching. Your baby will thank you for it. October 14, 2016
Rated 5 out of 5 by 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. May 26, 2016
Rated 5 out of 5 by 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! May 11, 2016
Rated 5 out of 5 by Good product My cat, unfortunately, has been placed on this diet due to his urinary condition. Chewy makes it much simpler to attain this food in bulk without having to drive to the vets office or hospital for it. October 28, 2016
Rated 5 out of 5 by Very happy with service Supplies arrive in the 1-2 days as stated. I use canned and dry Urinary SO and my cat loves it. He is healthy now since his operation and change in diet. October 26, 2016
Rated 5 out of 5 by My cats all love this wet food! I have multiple cats, 2 of whom have to eat the special urinary care diet, therefore all of them eat the special food! I started out with the Hills product, but they did not care for it at all. The minute I gave them the RC SO wet food, they all went nuts and cleaned their bowls. Here we are, 4 weeks later, and they still love it. I highly recommend this food if you need to put one or more cats on the urinary diet prescription food. October 14, 2016
Rated 5 out of 5 by I prefer the morsel type of food I ordered the 5 oz cans in an attempt to save money. However I just don't like the gel. It's personal--my cat loves it. The 3 oz cans of morsels means I open 2 cans a day and thus the cost is much more. My cat likes both. October 18, 2016
Rated 5 out of 5 by No more UTI problems My cat was diagnosed with stress related UTIs. He was prescribed the dry Royal Canin because he would not touch canned food. Twice, he became dehydrated and required veterinary care. Of course, canned SO was recommended. He refused to eat the SO in gravy, lost weight and had another stay in hospital. All is well since I started feeding the SO in gel. He eats well, though I have to stand guard to keep him out of the dog's dry food. October 10, 2016
