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.

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!!!

Bring Back Old Formula.

I am in agreement with many of the other people who have posted reviews. The new formula looks nothing like the older one. It is dry and developed a gross gelatinous film on the top of the can. The old version was darker and had a lot more moisture, which is good for the cats. Please go back to the old formula. This is really disappointing.

Need Consisten New Formula!

My senior cat has chronic digestive health issues and was placed on a special diet over a year ago. It's been a hit or miss with Royal Canin's Gastrointestinal canned food. Royal Canin improved the recipe in this item over a year ago, from a firm-dryish loaf to one that is more moist and has a bit more of a grainy texture and a bit darker, which my cat finally loved. For the past months, I have been receiving mostly cases of cans that have the new label, but the loaf is made with the old recipe and my cat doesn't want to eat it. I order 2 to 3 cases each month, which is costly. Chewy has been really helpful in providing support to return the partial complete cases, yet I am have had to throw away many cans that I open and find that it contains the old recip which also it makes it really difficult to maintain my cat on a consistent healthy diet. I contacted Royal Canin and a representative shared that all cans contain the new updated recipe but from time to time "the cans lose their moisture ", which sounds really odd for a new can of cat food. His only recommendation was to contact Chewy to return the cans and receive a refund. The explanation and recommendation doesn't resolve my daily challenge to feed my cat nor stress caused on both my cat, time and cost associated.
