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 and who are predisposed to weight gain
  • Moderate calorie content, compared to Feline Urinary SO, to help maintain ideal weight.
  • 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 for cats prone to both struvite and 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
  • Complete and Balanced Nutrition

Customer Ratings & Reviews

Rated 4.7 out of 5 by 79 reviewers.
Rated 5 out of 5 by My cat loves it. My cat is alive today because of the 'Urinary SO' formula. He had chronic UTI's and blockage. After expensive treatment and PU surgery to prevent his death, he was blocked again. The Vet treated him once again and sent me home with this food for my cat. He loves it!! Even though it is a little pricey, it's worth it to me to keep my friend healthy. I feed him wet in conjunction with dry food for the crunchy aspect. My cat hasn't had anymore problems and is back to playing with my dogs. August 11, 2013
Rated 4 out of 5 by Have cat with history of urinary track disease. Been using for years. Little expensive but my willing to pay for my baby. Fully packed can, no waste. So glad they came up with moderate calorie as my cat is on the heavy side. January 18, 2013
Rated 5 out of 5 by Great product Our cat Teddy has benefited greatly fom the Royal Canin Urinary SO can food. He's had crystals in his bladder which has brought him to the vet a couple of times. Since being on this particular food it has apparently solved the problem or kept it at bay. He is also a "big boy" at 18 lbs so he is on the moderate calorie. He loves the food. We also give him the same of the dry food occasionally. December 16, 2014
Rated 5 out of 5 by Max approves Max loves his new food. He has a tendency to get crystals in the urine and this prevents them. November 5, 2013
Rated 4 out of 5 by Urinary tract health AND low cal in one: FINALLY! This is the ONLY brand that makes a low calorie food for Urinary tract health. Food for urinary tract health tends to be very high in calories, and weight gain is a common problem according to my vet. I don't know why this is the only brand to correct the problem, but I'm glad they did. Chunks in sauce is not ideal, but fortunately my kitty ate it, even though he never likes his food like this. Cannot find this food over the counter: vet has to write you a prescription. Only just started him on this, so I don't know if it really will work, but fingers crossed. January 20, 2015
Rated 5 out of 5 by I never thought a cat food would make ME happy! Our cat, Mel, has a hereditary urinary tract infection.. and will have it for the rest of his life (and he isn't even two years old yet). We've tried a few different (ground/pate) formulas from different manufacturers for him, but it was a real challenge to get him to eat them. You know how finicky cats are to begin with. Now add to that trying to give him a 'prescription.' Needless to say, it didn't go over well. Eventually, a pet food company came out with two different 'shredded' offerings; these worked well. For a while. When we found this version of Royal Canin, we were desperate for something that Mel would be able to eat without us having to spoon-feed him. (Yes, we had to spoon-feed him the other prescription foods. Just like a child.) Anyway, "Royal Canin Veterinary Diet Urinary SO Moderate Calorie Morsels in Gravy" has made EVERYONE in this house VERY happy! Mel will eat his food now without any coaxing, prodding, pleading, begging, or bribing. (Just like a child, right?) Mel has been eating this for a two months now and his lab results have been perfect! Thank you Royal Canin, and thank you Chewy! November 4, 2014
Rated 2 out of 5 by This is a prescription food for urinary problems. My cat is 10 years old and has been on Urinary SO for 9 months. I have been switching her over to the moderate calorie over the last few months. She likes the dry version, but the (wet) moderate calorie only comes in the Morsels in Gravy (not the pate version) and she won't eat it. I have to buzz it up in my food processor and mix it with the pate. She didn't like it alone (after buzzing)! November 13, 2014
Rated 5 out of 5 by My cat loves this food! My cat has been eating the wet and dry food for a while now and loves it! He has not had a problem with his urinary tract since he's been eating this food. June 13, 2014
