About Royal Canin Urinary Health for Cats

Worried About Your Cat’s Urinary Health?

Your veterinarian is the expert on your cat’s health, so you should always consult with this trusted advisor to find the best urinary health solutions for your pet. Royal Canin works closely with veterinarians to develop cat formulas that help support urinary tract and bladder health.

How Can Nutrition Help?

Your veterinarian may recommend a Royal Canin Urinary cat food formula for your cat. These special formulations can:

Dilute Urine

This helps your cat urinate more often, which can help minimize time for stones to form.

Lower RSS

RSS methodology predicts urine crystallization and is used to develop diets that reduce the risk of stone formation.

Maintain Balance

A precise mineral balance can also help prevent stones from forming.

Set Up Autoship for Consistent Delivery

Last-minute dietary changes can sometimes upset your pet's stomach. Set your Royal Canin pet food order to Autoship to keep feeding on track and avoid unwanted disruptions.

About Royal Canin

What sets Royal Canin apart is their close collaboration with veterinarians. Through these professional partnerships, they strive to learn everything they can about pet health, including how different formulas perform for different breeds, sizes, lifestyles and therapeutic conditions. Ongoing research and development allows Royal Canin to keep providing the precise nutrition cats need for a range of medical conditions.

Expensive prescription pet food ruined in transit

This evening we received our regularly scheduled Chewy shipment. upon 1st inspection the box was savagely broken and ripped, as if the box had been meat hooked and dropped from a height, and the packing tape also failed. the cat litter arrived safely as it was shrink wrapped, BUT the very expensive Royal Canin Feline Urinary s/o prescription food bag was compromised and torn. There was cat food spilled inside the box and I don't know how long the contents were exposed during transit, and I don't know how much of the food was lost in the process. This is a 1st. Shocked & Disappointed, I would like a refund for the food, please. Thank you

A small (and I do mean very small) step up from Hills CD Urinary dry food.

Our cat flat out rejected Hills CD dry so vet gave a prescription for this . He does eat some ,not a lot but maybe 15 to 25 morsels a day of this. He also eat about 1 can of the Hills urinary wet food per day. Clearly he is no fan of these prescription diet food, but so far after about 3 months no more struvite urinary blockage . surgery alone was $1200 and he had a rough recovery. This Royal Canin SO is the only dry food he eats, His diet is probably 95% wet canned food and 5% RC SO, but as long he has no more blockage and he leaves nice big clumps in the litter box I have to give kudos to RC SO. He eats it, albeit reluctantly.

Good Product and Incredibly Fast Delivery

This prescription food prevents crystals in my cat's urine. After having to have him cathed twice due to blockage, this food has prevented that for at least the last five years. He does inhale it, so I have to limit how much he eats, but I mix it with this regular food, and it increases his water intake significantly preventing crystals. Highly recommend. Also, ordered on Saturday, delivered on Monday. Incredibly fast. Excellent job Chewy!

Picky cat approves

Urinary blockage issues instigated a need for a specialized diet for my 9 yr old girl. She is a picky eater and has eaten the same cat food for 8 yrs. We were given a different veterinary diet to try initially, she wouldn't touch it. We then tried Royal Canin. She decided it was worthy and has been eating it beatifully. Obviously the main reason was to treat bladder crystals and it has worked wonderfully.

13 years later and still doing well

We have a Maine Coon that has been eating this prescription food for nearly 13 years. He had an American Shorthair older cat he shared the house with and we could not set up two foods. So the Maine Coon started eating the prescription food and he has done amazingly well. He gets annual checkups and bloodwork and so far so good

Cat vomited 6 times in 1 day!

Yes, you read that correct! I have 2 adult cats. They have been vomiting up a storm from this stuff! One cat vomited 6 times in one day! Their poop smells atrocious and this food gave them bad diarrhea, which of course I have to clean off their fur daily. It was tracked all over our home. I feel so bad that I accidentally bought a second bag and gave this to them. I had bought a different kind in between and because I buy the largest bags and put them in storage containers, I completely forgot that I already bought this and had issues with it before and now I have two big containers of this garbage. On top of that, I bought another bag of non-prescription urinary food and stupidly mixed it with this thinking I could make it all last longer and not get their tummies so messed up by mixing it up but after reading these reviews, now I see there is a real problem and I'm harming my cats life. I'm so mad at myself for spending all this money on food I can't give them and feel awful for my poor babies. I just came here to write a review and I'm shocked at all the other reviews of the same complaint! They need to take this off the market. Chewy, please contact them and inform them of what's going on. This is really really bad food harming our poor furbabies. I've already lost a 4 year young cat to what I believe was a deadly can of wet cat food, I don't want to lose another one.

Urinary tract dry cat food

Royal Canin is a pretty good product. My male cat had urinary blockage, and I don't want to go through that again nor does he, so our vet prescribed a diet of urinary food to help keep his tract clear. My female cat eats it as well and so far so good

Useful

Excellent Prescription Diet for cats with Urinary Problems. Very tasteful for them and enjoyed by my cat with that problem. Never tires of it and always ready to eat it. Appears to keep problem under control with much satisfaction.

Excellent product and service from Chewy

Our cats have been on this for several years now. Treating the health problem very well, no recurrences. A huge thank you to Chewy who has been steady in filling our order throughout all the difficulties of the last few years. No worries we would have to change diet and what the effects would be.
