About Royal Canin Kidney Health for Cats

Concerned about Your Cat’s Kidney Health?

The healthy functioning of your cat’s kidneys is essential to them living a healthy life. Their kidneys serve as a filtering system that helps remove toxins and waste from blood. You should always work with your veterinarian to monitor your cat’s kidney health.

Support Your Cat’s Quality of Life Through Kidney Health Challenges

Feed a Specific Renal Diet

Your veterinarian can recommend the right diet to support your cat’s kidney function.

Encourage Drinking Water

Make sure that your cat always has fresh and clean water available. Offering them moist food can also support hydration.

Stimulate Your Cat’s Appetite

Offer your cat a nutritional option with different taste, smell, and texture to help ensure food intake, especially for pets with a poor appetite.

How Nutrition Can Help

Your veterinarian may recommend a formula that includes:

Digestive Support

A combination of highly digestible proteins, balanced fibers, prebiotics and EPA + DHA to support digestive health.

Antioxidant Complex

Enriched with a blend of antioxidants to promote tissue and cellular health.

Kidney Support

Modified phosphorous and protein to support kidney function.

Adapted Energy

Adapted energy content to reduce meal volume and help compensate for a decreased appetite.

Add Variety and Remember to Set Autoship

Offering a range of aromas and textures can help ensure palatability and adequate food intake. Also, remember to set Autoship to make sure that your cat always has their veterinarian’s recommended nutrition.

About Royal Canin

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.

I have 2 cats - one with kidney disease and one that is healthy. Can I feed BOTH cats this food?
Answer by ChewyNov 26, 2019
This food is intended to be fed to cats that were prescribed this by their Veterinarian only. It's recommended to consult with them before feeding to non-prescribed pets.

Is this kibble very hard, crunchy or a soft, chewy texture?
Answer by ChewyNov 29, 2017
This kibble is crunchy but easily digestible.

Can you use the different varieties interchangeably? For example, if I run out of the "A" bag, I use the "F" variety instead.
Answer by ChewyMar 09, 2021
The Royal Canin Veterinary Diet Renal Support A, F, and S foods can be easily mixed or rotated to provide multiple feeding options.

what is the protein and calcium levels on a dry matter basis?
Answer by ChewyMay 13, 2022
This recipe has a calcium content of 0.80% on an as-fed basis (0.87% on a dry matter basis) and a protein content of 22.22% on an as-fed basis (24.15% on a dry matter basis).

Both my cats became sick a few days after eating this. They developed diarrhea and now one of my cats is refusing to eat and very lethargic. The diarrhea turned bloody and now he’s not pooping at all. I thought this food was supposed to help them, but it did the opposite. He’s currently at the vet getting all sorts of tests and I’m in tears afraid I will loose him. The fact that it made both my cats sick at the same time makes me believe it was the change to this food. Beware :(

Cat Eats It!

My cat, who has never been a picky eater, has early stage kidney disease, but turned up her nose at the food prescribed by her veterinarian. Looking for an acceptable alternative, I asked Royal Canin for their equivalent products and received a list of three dry and several canned foods. I made an arbitrary choice of Renal Support A. While the cat wasn’t wildly enthusiastic she did eat breakfast and dinner after totally rejecting the originally prescribed food. Conversely, her brother, who does not have kidney disease, is more than happy to eat anything she leaves! Neither cat is very fond of canned food, but I think I will try to introduce some wet food going forward.

Not the same quality as RC's other prescriptions

Vet prescribed this food my cat had previously been on the SO diet so I expected him to like it however this one refuses to stay in his stomach. He throws up a few hours after he consumes it & I reached out to my vet to switch to something different.

Royal Canine Renal Support A for Cats

My cat has been doing better in Royal canine kidney support A; and she likes the taste, which is so important as she wouldn’t eat other brands.

Cat won't eat it after about 1 month of eating it

My CRF/CKD cat got tired of it after maybe 1 month, was hoping that rotating it with the other variations of this food that he'd go back to it after awhile, but he did not. He has liked RC foods in the past, and will eat other foods, so now he's having to eat other foods with rx vitamins phos-bind added, instead. I tried all 3 of the RC vet renal dry plus their wet, and he won't eat any of them after initially showing interest.

Great shape, crunch and flavor

This kibble is a hit with both kitties...most importantly RJ, who is facing early kidney disease. I am thrilled that he likes it. The shape and crunch mean he is also chewing this (sometime he just swallows tiny kibble bits). I don't feed this to our other kitty as he is still very young and needs a more protein dense food. However, he does steal some from RJ when I am not looking!

Tiggy has been eating this for years

I took in a 15 year old cat for a neighbor in such poor health she no longer felt she could properly care for her treasured pet. Tiggy was apparently prescribed this product a while back, and she eats it enthusiastically.

It is a good product, but my cat has sensitive stomach and we have to feed her less or she quickly chews and barfs it up. She is old so we have to be careful what she eats. Thanks for the quick delivery.

Early Stage CKD

I had been buying smaller bags of the S formula. This size is much more economical. I have 4 cats two seniors, one with early stage CKD or predetermined CKD. Everybody likes it so a bigger bag is better.

My cats

I'm glad to have a dry food option for the kitties. They like the can food a lot but will eat the dry sometimes.
