Promotes digestive health and optimal stool quality with highly digestible proteins and prebiotics

High calorie content allows cats to eat small meal portions and still get the nutrition they need

Helps manage GI health with omega-3 fatty acids, EPA and DHA, and a blend of soluble and insoluble fibers

Supports urinary health with the exclusive S/O Index, which creates an environment unfavorable to crystal formation in the bladder

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 her 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 with Royal Canin Gastrointestinal dry cat food (formerly Gastrointestinal High Energy) and Gastrointestinal cat treats as a complement to your cat’s diet.

Our cat was diagnosed through biopsy with IBD. He's been on this food exclusively for the past 4 years. The most recent formula change gets an all paws up from our cat. He wasn't thrilled with the old formula flavor and wasn't a good eater. He now gets super excited at meal times, finishes his portions in a few short minutes and then gets the zoomies! Although he's 15, he's so excited after eating he plays peek-a-boo around the house and basically acts euphoric. Thanks for the formula update, Royal Canin! Also, our cat had no problem changing from the old formula to this one. No stomach upset or IBD flareup - yay!

Availability and reviews

My cats had to transition to the wet food gastro S/O due to numerous changes in the dry food and some whoppers of vet bills. Now I read reviews of this food and see the same thing is happening…..changes in formulas, changes in product size and amount with no reduction in price as well as spotty availability. The most recent case had numerous dented cans and they weren’t on the perimeter of the shrink wrapped case either. It seems that production problems and quality are suffering. I am now in search of another brand due to the lack of consistency. If anyone has suggestions I would love to hear them. Transitioning cats to foods they aren’t accustomed to is a nightmare for them and their owners but the quality control and production seems to be absent with Royal Canin. It makes me nervous to think what is actually going in to the food as well.

Ripoff Price

They lower the gastro wet food from 5.7 ounces to 5.1 and have the nerve to keep the same price. After 5 years of using this cat food, I’m gone!,,,

Greatly Helped Digestive Issue

We are happy with this product and has greatly helped our cat from throwing up (she is on maintenance chemo for intestinal cancer). The flavor is not our cat's favorite so we add freeze dried protein (i.e., chicken, salmon, etc.). We break the freeze dried bits using a mortar and pestle and mix a couple of spoons with the can food.

Reorders for this product are unreliable and difficult to obtain. According to the veterinary pharmacy, this is due to Royal Canin's internal production problems. In addition, the last shipment arrived in unsatisfactory, smaller 5.1 oz cans -- same price, less product seems like a rip-off. My vet prefers this product to competitors but prescribed backup alternatives that are readily available, in larger cans, and less expensive. Royal Canin social media (e.g. Insta, Twitter) say nothing about these issues. Maybe try a little transparency for a change!?!?

Smaller Portion Same Price

My cat has been on this food for over a year, I just got my new shipment and the cans are .7 ounces smaller…. Why?

Inconsistent at best

My cat was on the high energy formula, then whenever it changed she was fine with it. Then, I got three cases of a much more watery and darker formula. By the time we to the last case she was seriously not liking it. I just received a new shipment, of SMALLER cans (5.1 oz. as compared to the old 5.8 oz.) and it’s the dryer loaf formula, which she is fine with. I came to this site looking to find feeding recommendations, and see that it’s still listed as 5.8 oz. I’m not sure I’ll continue using this food, I have a vet checkup next week and may make a change per the vet’s advice

Not as good as the old formula

My cat has no choice but to be on this food due to having IBD and an issue with crystals in her urine. Apparently you are the only game in town with a food that addresses both issues. However since the formula was changed she is eating less and vomiting more. Please change back to the old formula!!!
