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.

When you say 'GEL' is that the equivalent of a pate type food vs. the morsels.
Answer by ChewyJul 02, 2018
Royal Canin Veterinary Diet Urinary SO in Gel Canned Cat Food has a pate texture.

my cat sammy is 1 and recently was at the vet for a uti. Im in the process of switching him from fancy feast whitefish over to c/d that has a whitefish flavor. Right now I am mixing FF with the C/D both whitefish. What is the flavor of the royal canin "gel" wet food and same with the dry food
Answer by ChewyJul 29, 2017
This product contains Pork By-Products, Chicken Liver, Chicken and Chicken By-Products as the proteins.

My cat is presently on Veterinary Diet Urinary SO but he also eats about a TB of this daily to take medicine, making the can last 5-6 days. No stomach upset, smells fine, but is it too long to store in a 35 degree fridge?
Answer by ChewyOct 16, 2018
Opened cans should be stored in the refrigerator, at temperatures between 40 to 45° Fahrenheit, for a maximum of 5 to 7 days. Any cat or dog food remaining after that time should be discarded.

How much do you feed daily to an adult male?

This is the only food my cat can eat

My cat as struggled with urinary crystals. We tried Hills dry and then eventually only wet, and he still have reoccurrences. My vet suggested we switch to Royal Canin and I’m glad he did. My cat hasn’t had a flare up since. This is the only food he can eat or else he will get sick. When my cat first went on the food it was around $50 a case and the cans were larger. Now it’s over $70 and they’ve reduced the size of the cans! There’s nothing I can do but pay that price or risk hurting my cat. Royal Canin needs to reconsider what they’re doing to consumers!

my cat loves it

buddy had to go on the urinary so about almost 2 years ago and he loves both the wet and the dry food only thing is i sometimes it comes in pate which my cat loves because he was brought up on that kind of wet food but sometimes it comes in chunks in gravy then i have to mash it up so he will eat it all but it says the same thing on the cans loaf in sauce so what you get is 50/ big deal but the pate works much better for my cat and maybe other cats would be the opposite.either way it's worth it.

He likes it!

I was quite skeptical when the vet told us we should change to this food. My cat did not particularly care for pate and specialty foods, but thank goodness, he likes this one. It is very pricey, but he only eats one can for his twice day feeding, so that makes it a little bit easier. I wish it were a little bit cheaper, though. Costs like this for pet care can be prohibitive.

I have been reading people say that they changed the formula, cat doesn’t like the loaf and so on. LOOK AT WHAT YOU ARE GETTING!! Both loaf and morsels are available. Buy a single at the store and see which one your cat will eat. Come back here and order in bulk. I discovered that my cats like loaf. With the morsels they lick the sauce and leave some food behind. It’s unfair to leave a low rating because of ordering the wrong one.

Good Substitute

The Royal Canin SO 3oz morsels in gravy was on back order so we substituted the 5.1oz loaf in sauce. I was concerned because cats can be finicky. Good news, our cat loves the loaf in sauce. It's a little more work dividing the can into separate meals, but we save a little money.

SO special diet cat food

The important issue is the cat actually eating the new food. So far, he loves it. My part of the equation is the cost. It is much higher in price than the limited ingredient brand we were using. At least, Chewy is less costly than the veterinary.

No one will eat this

I was hoping for morsels in gravy and ended up with loaf. The formula changed during the pandemic and none of my cats will eat this. It's sad because the autoship sent me more. I will donate it I guess and let the shelter toss it after the shelter cats will also refuse to eat it.

Spoiled she is

Artimas is spoiled and the fact she’s prone to bladder stones makes feeding her a little difficult. She like the loaf in gravy best and it’s hard to find. Thanks for carrying her fav.

work but $$$

Goodness gravy does this stuff work great but holy cow the price keeps going up, buying in bulk you think you’d get a deal but it’s still almost $3 a can, worth it to avoid vet bills but wow that’s still expensive

Cats will not eat

Cats will not eat it. I have 7 rescued ferals and one has urinary blockages, so all 7 have to eat this food. None of the 7 will touch it they will only lick the juice, they will not touch the meat. They definitely prefer the other RX urinary brands.
