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 My cat loves it and begs for more My cat recently had to switch to a diet for urinary health and had not been eating canned food at all. He is somewhat picky and didn't always eat all of the morsels in gravy so I thought I would give the pate version a try. He LOVES it. He sits and watches my every move as I get it ready for him each day and eats every last bite. September 19, 2016
Rated 2 out of 5 by Veterinarian recommendation My cats don't love this food but the Vet wants my female one to eat it due to a bladder infection. The other two won't touch it and the one it was recommended for will only tolerate but would prefer dry food. September 22, 2016
Rated 5 out of 5 by Effective product I'm so grateful I found Royal Canin SO. My cat was diagnosed with a bad case of UTI and was very sick. The vet prescribed the other brand of RX urinary food but my cat would not touch it. After losing her appetite completely and becoming dehydrated AND an expensive trip to animal emergency, we were given sample cans of RC SO which she actually ate. She made a remarkable recovery and is doing very well on the product. No more sick cat...more like Tarzan cat! I am so grateful to God that I found this product and thankful to Chewy for offering it at a reasonable price. September 11, 2016
Rated 5 out of 5 by Great savings! I've been using this product for the last four or five years since my vet prescribed it. Works great at keeping my cat healthy and free of crystals! Just found the chewy site and the savings are gonna add up quickly over the vet prices not to mention the convenience of auto ship! September 13, 2016
Rated 5 out of 5 by My baby girl had urinary issues so the vet suggested Royal Canin cat food. My baby loves it and devours it without hesitation. My baby girl had urinary issues so the vet suggested Royal Canin cat food. My baby loves it and devours it without hesitation. September 11, 2016
