Rated 4.9 out of 5 by 197 reviewers.
Rated 5 out of 5 by This product immediately cured my cat's colonitis My cat was using this product previously, but our vet stopped carrying it and we switched him to another product. Then when he developed colonitis, I asked if it might work to switch him back to Fiber Response and the vet agreed. I ordered it from and it arrived 2 days later. Almost immediately the problem was solved and we are all very happy about that! October 26, 2016
Rated 5 out of 5 by Great dry catfood. This dry catfood is high in fiber as well as essential vitamins and minerals. One of my cats needed this high fiber food so the other three went on it too. The one that needed it is doing very well. Plus they all love the taste. October 28, 2016
Rated 5 out of 5 by My cat loves this food :) I have a 15 year old male cat, who has bowel issues and severe constipation. He was also taking lactulose but after being on the food for a while he no longer needs the lactulose. I pair this dry food with 1/4 of the wet and he enjoys it! October 24, 2016
Rated 5 out of 5 by Prescribed By My Vet My cat is overweight and was having some issues with his intestines, so she gave me a sample of this Royal Canin and Marcus really liked it. He doesn't seem to be as hungry all the time and his stools are better now. It's still too early to know of any weight loss, but so far so good. Thank you for carrying this food! October 16, 2016
Rated 5 out of 5 by Royal Canin gastrointestinal dry cat food does the trick! The Royal Canin food was recommended by our vet for a runny bowel problem and after a day or two, the poop was shaped and normal. We had tried other brands but nothing worked. also delivered fast with no hassle finding it at a store. October 10, 2016

Rated 5 out of 5 by Works Great! My cat Pookie suffered for 7 years with constipation problems. After many trips to the vet and trying every food on the market, we finally found this food! It works perfectly and my cat has been regular and problem free for the past year while eating this food. One bag lasts a long time, and Pookie loves the taste. October 9, 2016
Rated 5 out of 5 by Cats find it tasty Both my cats like this food. I was given a sample of the food by my vet yesterday. I ordered the food last night and Chewy called my vet for the RX. I received the food this morning. I noticed my cat that has constipation issues had a more productive poop already this morning. October 5, 2016
