Product Description

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 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 SO diet in gel is the healthiest lifetime diet for male felines My 3-year-old male feline tabby had to be catheterized at the animal hospital, because all the other moist food he was on had caused a urinary tract infection (UTI), as well as the formation of struvite crystals and stones in his bladder and urethra, preventing him from emptying his bladder and causing tremendous pain. The vet said ALL male cats should eat Royal Canin's urinary SO diet in gel for life and should never be given anything else--including treats, dried food or other moist food--because these cats are extremely prone to chronic UTIs and crystals. The reason male cats are predisposed to these kinds of urogenitary problems is because they're born with very short and narrow ureters, which can easily get clogged with stones and crystals, unlike their female counterparts. More tips from the vet: • Add only filtered water to each SO meal, which turns the food into a slurry, a consistency my cat adores. • Every time you feed your cat his morning meal, remember to add no more than 1/8 tsp Miralax powder to the slurry, so your cat can produce stools comfortably, without straining or ever becoming constipated. I totally swear by Royal Canin's SO diet; my cat adores it, and he's not had UTIs, stones or crystals since making the switch. Catsmeow28 Arden, NC May 12, 2016
Rated 4 out of 5 by My cat likes it, and it has worked so far. Despite being expensive, it appears the food is good for my 10 year old with feline bladder disease. He has been on this diet for about 6 weeks and his behavior and apparent health is much better. Previously he had been on a premium kibble and ate as he wanted. Over the years he had slowed down a lot and had constantly worsening hairballs. In late December he got blocked and spent a couple of days in the kitty hospital. After coming home we went through a few weeks of trying Canin Urinary SO wet and dry food as well as Science Diet C/D. Initially he rejected both brands, wet and dry. Finally, and on the third try with Canin Urinary SO wet food, he loved it. Since then he has eaten very well, and drank some water. Regulating amount has been a chore, he seems to want more than we think he needs. That said, we've only experienced one small hair ball and he plays like a kitten a couple of times a day. So far so good. February 25, 2016
Rated 5 out of 5 by Great price on this product! Just took my kitty to the Vet and zero crystals! So glad to have found this product at Chewey's. The price is cheaper than retail stores and at my Vet. My cats love this product and it addresses both types of crystals, struvite and oxalate. May 20, 2016
Rated 5 out of 5 by Very pallatable and effective I have three urinary issue cats and one of them is extremely picky. They all seem to really like this particular prescription diet. There haven't been any reoccurrences of their issues since being on this diet. May 20, 2016
Rated 4 out of 5 by Expensive but worth it. After having my cat in the ER vet for a blockage he needed a change in diet. Its expensive but Id rather pay it out slowly than in another ER visit. He eats it up, I wouldn't say hes a picky eater, but he has turned his nose up to a few foods. May 19, 2016
Rated 5 out of 5 by Yummy. After watching the food dish be left with uneaten food, it is nice to see a clean plate after each feeding. It is cat approved in this pet kingdom. The queen bee gives two paws up. May 19, 2016
Rated 4 out of 5 by Our cat does well on this After an expensive bout with a urinary blockage in November, our vet recommended our ten year old cat be put on your product for the rest of his life. He has about a quarter of a can mixed and softened with a little water in the morning. The rest of the day he snacks on the dry version. He seems to be thriving, full of energy. May 17, 2016
