HELPS DISSOLVE STONES: Innovative urinary tract cat food helps dissolve pure struvite stones and helps prevent calcium oxalate stones

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

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

HELPS PREVENT STONE REOCCURANCE: Specialized diet, with a reduced level of magnesium, helps prevent struvite stones from reoccurring

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 loaf in sauce wet 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. 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. And this specialized nutrition, with a reduced level of magnesium, helps dissolve pure struvite stones and prevent struvite stones from forming. 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 dry cat food and treats to complement your cat’s diet.

Royal Canin SO for dogs

I am so disappointed in this food. My dog has been on this diet for some time. It was a bit more expensive but saved us vet bills and it was worth it to avoid some issues she had in the past. However I agree with the other reviews. The cans are smaller, there is not doubt that the product itself has changed and the price has skyrocketed I t eh last few months. We payed 56$ not that long ago for 12 cans and now pay 77$. Unfortunately I don’t think we will be able to continue with this food. I feel that they are totally taking advantage of their customers. Shame on you! We will be looking into an alternative diet for our dear pet who clearly you do not care about.
Royal Canin response
Please know that the decision to increase our prices is never taken lightly, but it is necessary to continue to deliver a quality product for the pets that we serve. Our price increase was a singular occurrence at the beginning of the year. The rising costs of innovation, raw materials, packaging and transportation are reflected in the current price increase. I sincerely apologize for the frustration.

Crazy to shrink size instead of just raising price

Just plain dumb to shrink the size of the can. This is a medical diet for sick cats on controlled diets. Don't go changing the size of the can because that throws off everything when it comes to planning feedings. I'd rather just pay a higher price for the same size. Now I'll never ever buy a product from royal canin for the rest of my life

Too expensive for small 5.1 oz can that was 5.5 oz

My cat is young and needs urinary help but can has gotten smaller and now just went up in price all in the last year. I know some things are more expensive but instead of two cans a day my cat now needs three of small 5.1 oz. It’s too much to make 3 changes in a years time.

Royal Canin, very disappointed in them.

I’ve been buying royal canon products from my cats for many many years. I noticed a while back how their 6 ounce cans were actually 5.5 ounces. Now to my horror I see they reduce them to 5.1 ounce and still keep the same price. Instead of being honest and just raising the price they quietly make the cans smaller. Did the vet tell us to make their portion sizes smaller?

Also disappointed in pricing

It took years for me to regulate and stabilize my cat. It was a sticker shock when I first started feeling her this line. Needless to say, however much time later—and especially this past year or so—I am appalled at how much more this costs. First shrinking the size of the cans by .7 oz with no price change now a price increase of 12ish percent. All in roughly 6 months. Wow. I haven’t had a raise in 5 years. I have expressed my concerns with my vet. We will be considering other options for my kitty. It’s too bad because I will need to prepare for a tumultuous transition. She doesn’t deserve this.

Awful customer service

First the company stopped making the treats and now all of a sudden my car won’t eat the last eat batch of wet food we received. Previous to this batch it was her favorite thing. Now won’t even take a bite. There must have been a change in this product as she is eating other things but won’t touch this suddenly.

New customer, works for us

My 2yr old male cat was having urinary blockage, requiring a couple vet visits. We were reducing dry food, trying to encourage more water, and leaning away from seafood, but by the second visit he required expensive surgery. Then we relented and tried this. Haven't had any issues since. The kicker is, although he is a bit finicky about food, he likes this canned stuff. I had already been mixing some water into his meat, not only to get him more, but because he eats kind of weird; he licks it into his mouth rather than biting into it. So even though this 'loaf' does appear a bit dry (still says "in Sauce" here, that's not right), we were already used to mixing in water to get it to a more goop like consistency. I guess it's expensive, but if it avoids the health issues from now on, I consider it worth it.

No sauce - dry and dense

I too am having issues with my cat not eating the food with less sauce/gel in the pate. It is dense and very dry. I have purchased 3 different lots and the same result. I did just contact customer care and explained the problem and provided the lot numbers and BBDates. They stated there has been no change - but you can clearly see it when you open the can. My cat will not eat it after 10+ years of eating it. I have been able to find a few lots just recently with the same amount of sauce/gel as previously - but not anymore. I do not want to have to go through changing my cat's brand but I may have no choice :(

Disappointed in downgrade

Very disappointed in Royal Canin for decreasing the size and charging the same price. I would prefer if they would have kept the same size and amount of gravy and charge the price that they need. My cat has not been eating the food with less gravy/sauce in it. I’m very disappointed in the Urinary SO 7oz. cans size being downsized to 5.1 oz. and the price is the same price. I would have preferred they just charge more to keep the original size and provide the same amount of gravy or sauce as before. Now I open a can and the cat will eat it a little of it once and then will not eat any more until I open a new can the next day. I would prefer now if they would sell the Urinary SO loaf brand in the smaller 3 oz cans. At least not as much would go to waste. Now Looking into Hills Science brands as a replacement.
