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 cat's stomach. Set your Royal Canin cat 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 dogs need for a range of medical conditions.

finicky cat gobbles

This must be extra flavorful, because my cat usually sticks his nose up at his 'special diet' dry foods! I would love a smaller bag option, as I only have the one cat...but this bag must stay pretty fresh because he still eats 6-8 weeks after opening! (also no bladder problems since I started with this in January!) Try it!

Fixed the problem

My poor guy has FLUTD. I found out when he started spraying around the house, trying to tell me something was wrong. The vet put him on this food and the spraying just stopped!! I’m sure it helps make him feel better too. Never had any problem to get him to eat it. It must taste pretty good as my other cats want to eat it too. I have to sprinkle a couple pieces in their dishes too.

Better than Hill"s C/D!

I had all of my Kitty cats on hills S/O for several years because of one of them having stress. bladder issues. When they started puking, I started looking for other alternatives. I tried Hills C/D that most people switched too after the SO. But they both started puking on that as well and quit eating. This is a much better alternative for them and they eat the heck out of it. There's still been a little puking, but I think that's because they're eating so much of it after not eating at all. I will definitely be buying this again. Chewy was great because they refunded me for the food that didn't work, and as you know this stuff is super expensive. I will probably eventually. Convert my Kitty cats to fresh food as they get older, but in the meantime this is working, so I'm going with it.

Fills up my Cat

Have a large Maine Coon and he is new to this food and seems to like it. Chewy had it delivered the very next day after ordering. Was pleased with this quick service.

Good but by vet rx only

This cat food in addition to meds from the vet fixed my cat's issues with protein and crystal build up. He had to be on for 3 months, but we're now able to switch to a non prescription food for urinary health. While it's expensive, it costs a whole lot less than surgery. Also chewy was fantastic and had it delivered the next day!

This product saved me thousands of dollars.

This product really helped me out. My cat had stones in her bladder. 7 to be exact. After a month of taking it everyday she only had 1 stone left. And the doctor said that one still slowly devolve with time like the rest of them. I'm glad bc if she had the other type of bladder stones I would have had to pay thousands of dollars for surgery. The added benefit is that my cat LOVES the taste of this product. Before she had to switch to this food she would take a while to eat her meal. Now as soon as I wake up in the mornings she'll start meowing so I can give her food.
