Royal Canin Veterinary Diet Gastrointestinal Fiber Response Dry Cat Food, 8.8-lb bag

I was using another prescription brand the vet recommended along with a over the counter laxative. But my cat still was not able to get a complete poop. Switch over to this because if the reviews and I am so happy I did. It is the best I have been feeding for about 3 weeks without the over the counter laxative and she is pooping every day compared every other day with the other brand. And the poop are not hard nuggets they're normal poops. Would recommended to anyone who has a cat with mega colon problems. I am so happy I made the switch!

Just want to say that I really appreciate you guys. My kitty gets very constipated but one piece of helping him stay regular is his Royal Canin Fiber response dry food. I’d let him get low and went to a vet close to my house . They were out and gave me a different brand that was “the same thing”. Kitty didn’t like it and it was making his tummy hurt (I know this because I know my cat real well, for those wondering how I knew his stomach hurt). We were about to go out of town for a week and nobody around home had any of his food. I took a chance and ordered two bags from you guys. I knew you’d have to verify the prescription and was just praying it would arrive before we left. Well, few Just want to say that I really appreciate you guys.

I have to mix it with his laxative and I was grateful to have it to fix up for him before we left. Our sitter could have handled it I’m sure but I know exactly how he likes it and was thankful to be able to do that for him myself. She commented that he only ate out of the one big bowl, even though I’d left him 3 huge bowls of food. I said, yep, that’s his food he likes! … more

I have an 11 month old kitten who has mega colon and has been chronically constipated since he came to me at 6 weeks old. He’s also got a misshapen pelvis which doesn’t help the situation. We tried prescription medications, miralax, daily suppositories and still had to do enemas every other week. He was having a hard time passing stool, the texture was also very clay like. Once he turned 10 months old we started him on this food and while he still has to has the prescription medication, miralax and suppositories, the amount, frequency and consistency of his stool has changed ten fold. We were worried we would have to consider surgery to help this, which a positive outcome wasn’t even guaranteed I have an 11 month old kitten who has mega colon and has been chronically constipated since he came to me at 6 weeks old.

I do wish they made a wet food option in the fiber response line but it’s still a miracle food and highly recommend this to anyone with cats with GI issues. I work at an animal hospital so I made sure that all options were explored to assist this issue when he was very small and we explored all options (prescriptions, over the counter medications, suppositories, etc) and were starting to lose hope that we’d be able to help my little guy. Who knew that starting a new diet would completely change his quality of life! … more

My cat started getting constipated and absolutely nothing was working. Not even laxatives! Now she takes dumps the size of a dog's! The only downside is the price, but clearly it's been worth the money. I've started mixing this with another dry food to help make each bag last longer a 2 to 1 ratio of the royal canin to the other food. Still does the job!

Just wanted to express our appreciation to Royal Canin Gastrointestinal dry cat foods and Chewy for helping to save our little boy Chessie. Chessie has for many years suffered with Mega Colon disease and we have done everything possible for him to keep his colon and try to help him live a normal life. Recently, he was so packed inside we were considering having him put down, but thankfully our Veterinarian Dr. Costello suggested we clean Chessie out real good and start all over with this Royal Canin diet. In just about a week the results have been incredible. Chessie's trouble has been improved 100% and his life is much happier now. The staff at Town and Country have been wonderful to Chessie Just wanted to express our appreciation to Royal Canin Gastrointestinal dry cat foods and Chewy for helping to save our little boy Chessie.

I own a 21-year-old spayed feline who lives solely indoors. Despite a heart murmur, a few missing teeth, and arthritis in her front paws, she's in excellent health. However, in January 2021, she began experiencing severe gastrointestinal challenges, attempting to defecate in her litter box without any results. Twice, I had to take her to my local veterinary ER to have hardened stool removed from her colon via enema and manual extraction. During our second trip to the ER, the veterinarian recommended feeding her a higher-fiber diet (our cat was previously fed a different type of Royal Canin food), and, specifically, recommended this type, Royal Canin Gastrointestinal Fiber Response, Dry Cat Food I own a 21-year-old spayed feline who lives solely indoors.

Since feeding this new type of food, our cat has responded very well. She loves the flavor of the kibble and is once again able to have a bowel movement with ease. What's more is that she seems more energetic and happy. I highly recommend Royal Canin Gastrointestinal Fiber Response, Dry Cat Food if your cat is experiencing similar defecation challenges. Without making this switch, I fear that my cat would have never recovered from her gastrointestinal problem. Now, I'm hoping that in the near-future, Royal Canin makes a soft food version. Overall, though, Royal Canin Gastrointestinal Fiber Response, Dry Cat Food deserves the highest praise, and I'm thankful that Chewy provides distribution of this specific food, especially in the midst of a pandemic. … more

My vet put my Maine Coon cats on this food soon after they turned 1 and started getting hairballs. We mix half Fiber Response with half regular Maine Coon food. It totally stopped the hairballs. When we tried feeding 100% Fiber Response, they had diarrhea, hence mixing 1/2 and 1/2. With the pandemic, the vet clinic has routinely been out of stock of this food, and their supplier has it listed on back order and can never give an in-stock date. So I turned to Chewy and had no problem getting the order filled within a day and shipped immediately!

On my third emergency vet visit to deal with my cat's chronic constipation, the vet recommended a change in diet and suggested this specific brand. Even though it is dry food, the doctor mentioned having great success with other cats having the same problem as my kitty. I noticed a difference in 24 hours of my cat eating this food. He goes to the bathroom regularly in his litter box, isn't struggling when he does, and drinks more water. This prescription food is more expensive, but absolutely worth every penny!

This diet helps my older cat that came from a shelter. Her spine is arched and she has osteoarthritis. Before starting the diet, she was constipated. I have another, healthy 1 year old kitty that eats it too and he is doing great. Works for multi-cat household.
