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

  • Complete and balanced canned cat food diet recommended for cats at risk of developing lower urinary tract disease
  • This diet promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals.
  • Help prevent struvite, calcium oxalate and phosphate 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

Royal Canin Veterinary Diet Urinary SO in Gel Canned Cat Food is rated 4.7 out of 5 by 373.
Rated 5 out of 5 by from 2 Cats for me with bladder issues Over one week 2 of my adult male cats both became very sick with stones and blockage. The urinary diet was suggested, and despite the cost this food has become a way of life for all three of my adult male rescue cats. As hard as it was to shell out the vast amounts of money each month, all cats are thriving on this food since Feb. 2016. What I really like besides my cats obvious enjoyment of this food, is that it is firm from the can, not disgusting to touch if some misses the dish. My boys eat the gel and the morsels, another Royal Canin urinary canned food. They lick their dish clean, then each other's. I serve the dry low calorie Royal Can in urinary food while I'm at work long days and they can't wait to get the canned meal before and after work. For all the love and joy they give to me, they deserve the extra cost. helps in a HUGE way with the autoship with convenience and price discounts. I never run out and have to pay the horrendous local higher prices. Click, it's here in 2 days. Try it, your cats will thank you.

Rated 5 out of 5 by from Chewy is the greatest! When I was told by my vet that my cat would need to be on a prescription cat food for the rest of his life, my heart sank. Fortunately, I was told about Chewy -- that the cost would be less, that the food would be delivered to my home, and that they guaranteed their products. But there's more! When my cat wouldn't eat the first prescription food, Chewy cheerfully refunded what I had paid. You can save by signing up for autoship, and still delay a shipment or ask for it to come sooner. The products I have ordered from Chewy have been of excellent quality. My cat has not had a recurrence of his urinary tract issue since we started the prescription foods. The shipments arrive in good shape and exactly when they are due.

Rated 4 out of 5 by from One of two veterinary diets recommended to us My cat likes the consistency of this gelled pate better than Hills c/d which is more like ground food but I couldn't get him to eat it at first. He'd peck at it, eating a few bites at a time. He was a dry food kibble kitty before trying this so it took weeks to gradually get him to eat regular servings of any wet food. After an initial adjustment period transitioning to SO cans, it kept his urine clear of struvite crystals. I wish it wasn't made with pork and grains but all of the recommended Rx diets are. These are the diets that have been clinically proven to dissolve and prevent struvite crystals.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from My cat likes it! My cat had to go on a prescription diet due to crystals. I wasn't sure how he was going to react to this change. He does eat it and likes it. At his last follow up check up, his crystals were gone. I will be looking into buying him some crunchy food. He misses his crunchy food. It's such an awful change for a cat when all of a sudden he can't eat what he has for years. I'm so thankful that there is a product that helps his condition and that is appealing to him. Thank you Chewy for being so helpful and understanding during a difficult time for us.

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from Comparable prices and Free Shipping! One of my cats requires special food but I didn't like going to the big box store and lugging a month's supply home. I avoid all that mess, save time, a little bit of cash, and spare my back by having it delivered by CHEWY. Cases of canned cat food arrived quick, and were adequately packaged. No complaints. This is where I'll be getting cat food from now on.

Rated 5 out of 5 by from Fast shipping and good customer service I did have to call Chewy to prompt them to contact my vet, but when I called I spoke immediately with a human-no wait time! He was friendly, contacted my vet immediately, my order shipped that day and arrived the following afternoon! Wonderful customer service, and my cat seems to really like the food too, bonus!!
