About Royal Canin Gastrointestinal Health For Cats

Worried About Your Cat’s Digestion?

Your cat’s gastrointestinal (GI) system helps support the rest of the body by properly digesting food and making sure to extract the nutrients needed for overall health. Your veterinarian is the expert on your cat, so you should always consult with this trusted advisor to find the best gastrointestinal health solutions and management options for your pet.

Know Your Cat’s GI System

  1. Mouth: Where hair ingestion from grooming can cause the formation of hairballs.
  2. Stomach: The first part of the GI tract, where inflammation may cause vomiting.
  3. Small Intestine and Pancreas: The small intestine is responsible for nutrient absorption and the pancreas aids digestion.
  4. Large Colon (Transverse): Responsible for forming stool.
  5. Large Colon (Descending): Integral to stool formation—any disruption here may lead to constipation or diarrhea.
  6. Rectum: Where stool leaves the body

How Nutrition Can Help

Talk to your vet about your cat’s GI tract and what diet can help keep it healthy. Your veterinarian may recommend a Royal Canin GI formula that is:

Rich in nutrients and easily digestible

Balanced for good digestion, with a blend of fibers and prebiotics to support digestive health

Highly palatable to encourage eating, even when appetite is decreased due to gastrointestinal upset

Find The Perfect Balance

With a dry and wet feeding routine, dry food supports positive oral health while wet food supports healthy hydration.


Keep your pet's feeding on schedule.  Set your order for Autoship to make sure you always have their veterinarian-recommended nutrition on hand.

Questions & Answers

10 Customer Questions

Does this diet help cats have less frequent bowel movements?
Answer by ChewyJul 09, 2017
This diet has high energy content which allows a reduction in meal volume and a decreased intestinal load. This may in turn result in smaller or less frequent bowel movements.

What is the difference between Royal Canin Veterinary Diet Gastrointestinal High Energy Dry Cat Food, Royal Canin Veterinary Diet Gastrointestinal High Fiber Response, and Royal Canin Veterinary Diet Gastrointestinal Moderate Calorie Feline?
Answer by ChewyFeb 27, 2019
This High Energy recipe is specifically formulated diet helps manage feline gastrointestinal disease in cats requiring a higher energy density. The Fiber Response recipe is specifically formulated prescription diet helps cats with digestion issues or food allergies achieve optimal health. The Moderate Calorie recipe is specifically formulated prescription diet helps cats with digestion issues or food allergies achieve optimal health, plus it features a reduced fat content to help limit weight gain in cats with a tendency to become overweight or obese.

One of my cats is on this high energy diet. Would it be suitable to feed to my other two cats also?
Answer by ChewyMay 06, 2018
Since this is a prescription food formulated to meet specific diet restrictions from known health issues, this food should not be fed to any other animal than the one prescribed due to the restriction of specific nutrients. Prescription diets can be detrimental to an otherwise healthy pet if that pet doesn't have the ailment for which the food is designed.

What are the DRY MATTER phosphorous and protein percentages for this formula?
Answer by ChewyJul 22, 2022
This formula has a phosphorus content of 0.97% as fed and 1.06% on a dry matter basis. The protein content is 30.85% as fed and 33.53% on a dry matter basis.

Diva Cat with Digestive Woes

Moonpie the Diva Cat was pooping pudding for weeks and weeks. Vet ran full gamut of tests which all came back normal. (Hooray for Moonpie!) This pointed to Gastro-Intestinal issues (lower GI.) Put her on a short course of meds to calm things down and switched to this food. Now she poops like a normal cat and is much happier. The litter box smells better too. She is very finicky, but she switched over to this food no problem. Well, actually, she really liked this food and decided to overeat the first time (it was mixed in with her other food to make the transition), so she did barf a huge pile of food the first day. No issues since then! Wish is was cheaper, but all of these veterinary diet foods are very expensive, so this one is no different.

Life Saver for My Cat

My 9 year old cat, Arya, was diagnosed with pancreatitis several years ago. I tried so many types and brands of dry food over the years which ultimately made her disease worse. Both of my cats have always preferred Royal Canin products so I asked my Veterinarian to prescribe a dry food for Arya. I just finished the transition from prescription Science Hill to this product. Both of my cats love it because of the enticing aroma and the small sized kibbles. Arya is gaining weight; not vomiting; and energy level is back to normal. Just wish it was less expensive but we spare no expense for our little fur babies.

Never been more happy to see poop

My eight year old cat has been dealing with chronic constipation for years. Already went down the whole road of using laxatone gel, pumpkin, and miralax and nothing really helped that much. It was getting so bad she was throwing up from straining and I knew I had to try something else. Within 24 hours of using this food mixed with her old stuff she actually had the most healthy poop I have seen in years. It’s worth the price for her comfort and will last much longer being mixed. This stuff is a miracle. I’m so happy and I know she is too!

This food really works. It’s the best!

Our cat had been vomiting daily. We started him on the Royal Canin Gastrointestinal dry cat food 2 weeks ago. This food has really worked to settle his stomach. He has not vomited once since starting this food.

Cat with gastrointestinal problem

This seems to be good food for the purpose intended. Sam, my 6 year old has pancreatitis flare up’s from time to time. This food has helped keep her home instead of vet hospital care. The only thing she is tired of the taste. Wonder if it comes in different flavors?

Gastrointestinal relief

My cat was having problems for quite a long time until his doctor decided we should try this special food. I was able to switch him over to it easily because he likes it very much. Since he’s been eating it for three months now I’ve seen a tremendous difference in his health and behavior. I intend to keep him on it. Ordering it from Chewy is cost effective and trouble free.

Mega colon

They have changed their formula, as of April 2020. It used to work for my cat's Mega Colon, but no longer does. Please bring back the old formula! We have started him on Miralax too which is helping, but we shouldn't have to add this while we are paying $$$$ for a prescription food. I have contacted Royal Canin directly, who confirmed they had changed their formula.

Exceptional Product and Service

My Vet recommended this for my cat that was having problems not keeping her food down. Since starting this gastrointestinal diet she has been fine. Highly recommended by me.

Allows my cats to have dry food again

I give this as a treat to my 3 senior cats. Only a tablespoon, twice a day. My vet allowed this for my cat with FUS because it's got the S/O Index. (Is on the S/O Index? I don't know how that goes.) He hasn't been able to keep dry food down in years, but this food agrees with him. He's having trouble with his appetite and keeping his weight up, so this is also boosting his appetite. I had stopped giving all of my cats dry food to avoid problems, but they all like this one, and they're enjoying having dry food back in their diet.
