HEALTHY DIGESTION: Highly digestible proteins and prebiotics promote digestive health and optimal stool quality

HIGH CALORIE CONTENT: Allows cats to eat small meal portions and still get the nutrition they need because of the adult cat food’s high calorie content

CAT GI HEALTH: Omega-3 fatty acids, EPA and DHA, and a blend of soluble and insoluble fibers help manage GI health

URINARY SUPPORT: The exclusive S/O Index, which creates an environment unfavorable to crystal formation in the bladder, supports urinary health

You’ve tried everything to help with your cat's GI issues, whether those are vomiting, diarrhea, or lack of appetite. And while bland homemade diets are often used for digestive upsets, your cat could be missing some key nutrients to help them fully recover. But with the help of your veterinarian and Royal Canin, there’s not just hope—there can be a true difference.

This palatable, digestible GI cat food supports digestive health with high fat and calorie content, so you can feed your cat small portions to support their sensitive stomach. This also helps underweight cats or cats who are eating less get the calories they need. Prebiotics help maintain the balance of good bacteria in the gut. A blend of dietary fibers supports healthy digestion for optimal stool quality. Omega-3 fatty acids, EPA and DHA, from fish oil help nourish and soothe the GI tract. And the exclusive S/O Index supports urinary health by creating an environment unfavorable to crystal formation in the bladder. Ask your veterinarian about pairing this diet with Royal Canin Gastrointestinal wet cat food as well as complementing with Gastrointestinal cat treats.

Tempted the appetites of all three sick cats

All 3 of my cats (age 5, 7 and 14+) came down with a short-term viral illness that gave them gastrointestinal upset (both ends) and they were not interested in eating. My mother offered me some of this dry food. Her cats are on this food as they DO have chronic gastrointestinal conditions and vomit with other food. I am pleased to say that, while my (normally unfussy) cats were barely sniffing at other foods, that they did enjoy this blend. I would like to have it for my oldest cat who is starting to lose weight, but I don't know if it is appropriate for his current dietary needs, which is the R.C.Urinary support (for his tendency to have crystals in his urine).

Gave my cat a longer life

We’ve been using this food for my cat Chino who has mega colon. Without this option he wouldn’t be here today.

One of my cats started have GI symptoms out of the blue and was initially prescribed the wet version of this food and liked it but once we were able to switch to the dry he was so happy. He gets so excited when it is meal time and he looks so much healthier. Prior to switching he struggled to put on weight and now he has been able to maintain a healthy weight. And his GI symptoms are gone!

Please change the design

I've bought the wrong bag of cat food more than once now because all the packaging looks exactly the same - This time I bought the High Fiber one by accident. If you changed your packaging - even just in different colors - for the different types of cat food, I'm sure many people could avoid this in the future!

Please offer it in a smaller bag

I bought this, but my cat sort of liked it and picked at it. Then he liked it, but it is not the only food he eats, so the large bag which wasn't fresh to begin with, now smells rancid, I won't feed Marky that. So $52+ shipping and I can't even donate it to the local cat group because it went bad. I store in tightly sealed plastic containers which should have preserved it. Please offer smaller sizes. Also, it works well, my cat does not need to be de-obstipated when on this..... however keep other kitties out of it, they will get diarrhea!!

Neither Cat Likes This; Why only the BIG bag

My vet just recently prescribed this food for one of my cats that has soft stools. Prior to this she ate any type of dry food we used, but almost exclusively Iams. She does not like this food. My other cat, who eats anything, also does not like it. I wish Royal Canin offered a smaller trial-size bag instead of the 8.8 lb bag. I just wasted $55.

Rectal Prolapsed Kitten

I have a 6 month old kitten that was suffering with rectal prolapsed. he undergoes a surgery and managed to survive. It works great and I'm truly grateful as this can help my cat to poop normally. Unfortunately, it is very pricey as I live in Malaysia. A bag of 2 kg is MYR 100-something :/ but I understand why the price point quite high.

So very sad...why the recipe change? :(

My 12 year old girl was having hairball issues and my vet recommended this to try and help. It did amazing for her, hairballs have been kept at bay and she absolutely devoured this stuff. She even began crying for it each morning and night upon hearing me open the can. I soon began to run out of the supply my vet sold to me and had to purchase a new case of cans. To my surprise, I open the first can upon arrival and it looked, smelled and even mixed differently than the original loaf recipe I was giving her. One thing I noticed, the fish oil looked to be too much and the scent was something of a spice smell possibly added? I hoped for the best, and prepared it for my baby girl. She walked over to it, smelled it for a moment, and simply walked away - not touching it for the rest of the evening after I gave her a chance to get used to the new offering. I ended up feeding her the old food supply I still had on hand before I began feeding her this line. I'm glad I had some left! Why did you guys have to change the recipe? I see so many others on here complaining about the same issue, and it still hasn't changed back? Now I have to find something else from another cat food line that can hopefully be close to this recipe. Super bummed for my girl and even more bummed that I had a remedy for her issue and now I'm back to square one hoping for the best again.

Cats loved it

I have the worlds pickiest cat with urinary issues. She loves this food! It's a bit spendy though.
