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.

Smaller cans, worse value

Ignoring that the website still advertises the cans as being 5.8 oz, but they've been reduced in size to 5.1, this is simply a pain because you have to recalculate the feeding amount and use more cans.

Seeking alternative brand due to smaller can size

I am looking into other brands due my displeasure of the (smaller can size/price). Bad idea all around (customer satisfaction, carbon footprint and environmental impact). I can’t find the magnesium content for the SO so that I can compare with Science Diet and Hill’s uninary products.

Why, why, whyyyyyy would you change the can size?

I mean, we all know why... but it's so frustrating. I will pay more for an already expensive food because it is what my cat needs to stay alive, all of us here are a captive market. You have our business... but, come on, the ol' can size switcheroo is an such an insult. I would threaten to use another product or spend my money elsewhere, but you know as well as we do that there aren't other options. So I will continue to begrudgingly buy your product because I have to, because I want what's best for my cat, but the second I have a viable option, I'm out.

Add inconvenience to an already pricy product

12% small cans now for the same price. Our cat has been on this for many years and due to scaring in his throat (due to a horrible vet), we have to add 4 tablespoons of water to each 5.8oz can and mix it up so he can swallow it. What's 4 tablespoons minus 12%? PIA! If you need to bump your bottom line, just raise the already high price and stick it to us that need your product and don't mess with the portion size of the can for those of us who rely on it. If it were easy to find another product for our cat I would do it.

Horrible Decision

Our boys have been on the 5.8 royal canin urinary SO for years. The price has always been high but we tolerated the expense. The price went up over 15% in the past year, and now Royal Canin has reduced the size of the can by 12% without reducing the price. This increases my cost dramatically, and also causes a problem determining how much food to give each cat. Bring Back the 5.8 oz can please. I am looking at alternatives due to the changes the company has made in the product.

Well, you used to make a 5.8 oz can

How can you stop making the 5.8oz cans? It's SO NOT NICE to do to the people who need your food the most. I'm actively seeking other brands. You will NOT be getting my business anymore. Peddle your small cans to someone who can afford it.

Great food,ridiculous size can

For years, this food has helped my cat Rocky. After suffering bladder stones and having an operation, the Vet put Rocky on this food exclusively. He loves it, which is great because it is the only thing he can eat to prevent problems. The can size has just been reduced from 5.8 oz. to 5.1. Seriously? Am I supposed to feed my cat less food? Now I am forced to do complex mathematics to make sure Rocky get the same amount of food that he had before. Please bring the 5.8 oz. cans back!

Deceptive Packaging.

I am so incredibly disappointed in the recent change in can size. According to your website you still list the can size at 5.8oz yet my Chewy order arrives this month with 5.1oz cans. This shorts me 3 cans per case and affects the amount that I am having to feed. Additionally the price has increased by almost $10 a case in the past year. The decrease in can size is the last straw for this family. We will be asking our vet for a suitable alternative to your brand.

SMALLER SIZE SAME EXPENSIVE PRICE

First off: this food helped my cats with urinary tract problems, so very happy with the efficacy. I AM NOT HAPPY to see RC reduce the can size from 5.8 to 5.1 ounces, while the EXPENSIVE PRICE STAYS THE SAME! Almost $60 PER CASE!! So now we are shorted nearly 3 cans per case. I'll have to start looking into other options. VERY DISAPPOINTED.

Did you changed for,USA? Why?

My cat has been on the same diet of Urinary SO for 9 yrs. Never had an issue. I have been wondering if it was a new formula for a while now. Recently for the past 2 mos my cat has been having diarrhea and loosing weight. He is a strictly indoor cat since he was 6 weeks old and he is now 10yrs. Nothing has changed in our house, no new food, etc. He has been to vets twice, once as an emergency due to diarrhea and lethargic. All the tests have come back negative. The only thing changed recently is a new shipment of the SO canned food. Did you change the formula and why? I see others have been having issues too. He still eats the food but is not having normal stools eve since started the last shipment. Please reply!
