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 ingestion of hair and formation of hairballs can occur, due to frequent grooming.
  2. Stomach: the first part of the GI tract, where inflamation may lead to vomitting.
  3. Small Intestine and Pancreas: where the small intestine is responsible for absorption of nutrients within the diet and the pancreas aids in digestion.
  4. Large Colon (Tranverse): which is responsible for forming stool.
  5. Large Colon (Descending): which is responsible for forming stool; any alteration to this process may lead to constipation or diarrhea.
  6. Rectum: where stool leaves the body

How Nutrition Can Help

Talk to your vet about your concerns for your pet's GI tract health. 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.

can you please explain what the S/O index is all about ?

Better Than I/D. Easy Transition & Loves It

My Sphynx had beed on Hills Prescription I/D almost her entire life (8yr) Suddenly she started puking (not sure if it was food or something else) The vet suggested a food change, plus restricted calorie since she is 19lbs & could never lose weight that started after the I/D. I gave her "samples" & she LOVED. I introduced slowly mixing w/ I/D. Not puking...nothing! It's been about 2 months & she looks thinner and just healthier in general! I wish I would have discovered this a long time ago!!!

Really Disappointed

I was so looking forward to this food my vet prescribed to see if it would help with my cats digestive issues. However, he threw up immediately after eating this the very first time. Now I have a huge bag and I'm afraid to feed it to him again. I guess I'll have to donate the bag to a local shelter. My kitty is not back to Blue Buffalo Tastefuls for Sensitive Stomach, which has 1st ingredient as deboned chicken. I was disappointed to see the 1st ingredient in this Royal Canin is brewers yeast. Maybe Franco is allergic to yeast?! :(

Good Choice

My guy eats wet version of this, well sort of; he nibbled it, vs devouring this! Good to know dry can still keep him regular!

Easy Transition

The vet switched my car's diet. Was trying to follow the transition process, but he had other ideas. He ate all this new food and left the prior food in the bowl. Guess he likes it alot!!

She likes it

My cat's cholesterol and weight was up at her last exam. The vet suggested going to Royal Canin Moderate Calorie Gastrointestinal food. She is super picky and I was afraid she would have a hard time adjusting since both the color and shape are different from her old food. She scarfed it up like it was a special treat. She likes it. As always, Chewy customer service and delivery is excellent.

a nice way to boost my cats fiber intake

This food takes care of a couple of digestive issues with our cats. All good. I mix with other dry food and it settles their stomachs right down.
