HELPS PREVENT STONES: Specialized adult cat food helps dissolve pure struvite stones and helps prevent calcium oxalate stones

WEIGHT MANAGEMENT: Low calorie cat food (10% less calories than Royal Canin Urinary SO Dry Cat Food) for ideal weight maintenance

BLADDER HEALTH: RSS methodology for cat bladder health helps lower the risk of crystal formation

S/O INDEX: The exclusive S/O Index creates an environment unfavorable to crystal formation in the bladder to help support urinary health

When your cat has urinary issues, easing their discomfort requires special care. But with the help of your veterinarian and Royal Canin, there’s not just hope—there can be a true difference.

This veterinary-exclusive dry cat food was developed to nutritionally support your adult cat’s urinary tract and bladder health. It increases the amount of urine your cat produces to help dilute excess minerals that can cause crystals and stones. Moderate calorie content (10% less than Royal Canin Urinary SO dry cat food) helps them maintain a healthy weight. Relative Super Saturation (RSS) methodology is used to help lower ion concentration in urine, which contributes to stone formation. This formula promotes a urinary environment unfavorable to the formation of both struvite and calcium oxalate crystals. Lower urinary tract issues may be a recurring concern for some cats. Talk to your veterinarian about keeping your cat on this urinary cat food for long-term urinary support. And ask them about the right Royal Canin wet cat food and treats to complement your cat’s diet.

Very disappointed new formula

I have purchased this food now for about close to two years, and my cats do not like the new formula. Typically they can eat the top 1/4-1/2 of the bag, but past that even the cat that will eat anything, walks away from it. I close the bag tightly and even flip it upside down to see if that works if some flavors are settling. They also get sick on it like the others I see in the review. They are also opposed to the wet version as well. I have to throw 1/2 of the bag away every time I purchase it. Very disheartening. The old formula was a little better. It is very challenging since the boys need the SO food. We even buy the medium sized bag.

Formula Change

My cat used to eat the old formula (green label) and we had no issues. I called Royal Canin when the bag switched to the (gold label) and was told that they added "Wheat" to the ingredients. This may be the problem why everyone's cats no longer like the food or vomit a lot when eating this food. Wheat can be bad especially if your cats is allergic to wheat which a lot of cats are. Also, the same thing with the wet SO food, my cat will no longer eat it.

Cat Gained Weight and Vomited with new Formula!

I used to feed the RCVD Urinary SO to both my cats and they were overweight and would have the occasional hairball but I was working in feeding them less and doing stuff to help hairballs. When the Moderate Calorie diet version came out my Vet recommended it so of course I switched and ever since both my cats vomit without hairballs, one of the gained weight even though I have restricted the calories more and the other cat who loves to eat stopped eating it and was recently diagnosed with Diabetes (this is mot likely unrelated to the food however this is a very high carb diet which I didn’t not realize.) I will be switching my cat with Urinary issues to a different diet. The only good thing and the reason I gave 2 stars is because since being on the diet my cat didn’t get anymore struvite crystals.

I am a veterinary assistant - Dissatisfied

I have worked in veterinary medicine for 8 years. I have all 3 of my male cats on urinary S/O or an Royal Canin S/O indexx food. The S/O Mod Cal food makes my cats excessively vomit and has done so for several months. This did not used to be the case. They used to love eating it and would hound me to be fed. Now when it put it down they just look at me. There is no way that Royal Canin hasn't changed their formula. I'm really annoyed about this and won't recommend it to clients. I recommend sticking with the regular Urinary S/O food that is not the Mod Cal diet or switching to another Royal Canin diet that has the S/O index in it. I also feed the Royal Canin Feline Dental Diet b/c it has the S/O index in it. I do not have problems with this food and my cats teeth (8 yrs old) look like a 2 yr old cat. I've never brushed their teeth and they've never had a dental.

no bladder stone worries now

my female cat developed bladder stones and thankfully they were small enough to be flushed out without surgery thanks to my great vet. He recommended using prescription dry food. My cat loves this one and has had no issues and it's been at least six months. Highly recommend.

Mixed results after formula change

The first bag of Urinary SO Moderate Calorie dry food made my cat vomit after every meal. Royal Canin told my vet they couldn't think why that would happen and offered to switch the bag out for free "just in case". The first bag was my usual large bag (like 14lbs I think?). I asked for a replacement bag in the smaller size in case my cat continued to vomit and I was stuck with the extra food. She does NOT have an upset stomach and is not vomiting now that we're using the smaller replacement bag of the new formula. However she doesn't really seem to enjoy the flavor of it and making her eat is now a struggle, when before, well, she was on the moderate calorie for a reason.

not good

My cat had been on this food both canned and dry for 2 maybe 3 years and it did great, no stones. She started getting sick last month, vomiting, not eating (although she was hungry), signs of bladder issues ...spent $$$ at the vet, she was forming crystals again...We had just started her on the food from the new packaging so I got online and discovered the formula had also been changed, confirmed this with a phone call to the company. Changed to a different brand of food and she is back to normal but I am now left with an entire case minus 1 can and almost an entire bag of food that she refused to eat ( I did try with the dry food). Being we have it auto shipped from another company they will not take returns on prescription food. Had we or our vet been informed of the change, we could have tried to introduce it gradually but the fact that she started to form crystals again leaves me wondering. Not real happy the price went up either.

very effective!

I disagree with all these bad reviews. My cat had 5 bladder stones. I started to feed her the Urinary SO dry and canned foods gradually mixing and increasing the amount of this new food until it was all the new food. She had no issues with the old or new version of this food and it dissolved all 5 stones within a month and her coat got nice and shiny and the dander was gone. As long as you gradually introduce the new food your pet should be good.

New Formula Is Bad

We have three cats and one has the prescription for the SO food. They had been on the wet and dry food for two years and loved it. Within the first month of using the new formula dry food, my cat with the prescription had to go to the vet because he was very sick. We used up our old batch of wet food and tried to feed him the new formula of the wet food and he wouldn't eat it, nor would either of our other two cats, one of which eats everything. I came on-line to see if the food changed and found these reviews. Our vet has changed the prescription to a new brand, which all our cats love. Seems awfully coincidental that our cat had no issues for two years and then became sick within weeks of the new formula change.
