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 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 Cats cant wait go eat! My little guy had a bout with UTC and is not on a strict diet. He was very pleased when he got to eat soft food on a daily basis. He loves this food and gobbles it down. My other cats can't wait for him to finish because they get the leftovers! July 26, 2016
Rated 5 out of 5 by This food saved my cat from major bladder surgery. Great product and great customer service from Chewy staff. I used the online chat for help when I ordered a different flavor by accident and my cat would not eat it at all. They sent me the new flavor which arrived the next day and I didn't have enough to deal with shipping the other food back. I donated it to my vet. July 25, 2016
Rated 5 out of 5 by Cats loved the taste I have found that my cats often do not like the Rx food, but both seem to enjoy the SO. Hopefully it will work to help the male's bladder crystals go away. I have also noticed a drammatic improvement in his coat. He is shinier, and the bit of dandruff is now gone. I give them a little of the dry version of SO as a treat, since I want him to produce as much urine as possible. Ordered from Chewy under auto ship program. Arrived in 2 days (as promised). Well packaged, and saved considerable $$$ when compared to other providers. July 18, 2016
Rated 5 out of 5 by Keeps my little boy cristal-free My vet put my male cat on this diet when he had crystals in his bladder. His urine amount was tiny. After being on SO for just a week he showed marked signs of improvement. It is also filling so he isn't crying for food all the time. I highly recommend this food if your cat has crystals.
