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

As a last resort (before considering surgery for mega colon) I decided to give this food a try at the recommendation of my vet. I was skeptical because I have used a wholistic approach over the past year, in addition I don’t believe in a dry food diet for a cat with constipation. But, my cat really likes it and it is actually working. He has had regular bowel movements since starting on it a month ago. As a caveat, he is still on meds, and we are giving him subcutaneous fluids at home, but none of that was working well before this food. So glad I tried it. Chewy was quick to fill the prescription and it came within a few days.

I have a 9 year old (short hair tabby ) stray . My vet thinks he is part maine coone, which are known to have constipation issues. He had a spinal injury which makes it even harder for him to pass a bowel. He got 3 enemas at the vet and this is the food he was put on. Right now with this mixed with giving him 2 doses of SMOOTH BM everyday he is passing poop normally now. I am taking off a star because this food is very expensive for a small bag, but it seems to last my cats longer than cheaper food. Also I noticed their poop smells less than normal. There are a lot of fillers in this food but its helped my kitty (:

Our vet put our long-haired cat on this high fiber food to help with her massive hairballs. We had tried everything - making sure she had plenty of water, offering cat grass, daily brushing, a primarily wet food diet. Nothing helped and her hairballs were large, frequent, and caused significant distress. Once we started on this food, we noticed a change right away (namely in the form of a LARGE poop!) This food definitely means big stinky poos, but it also means less frequent hairballs that come up much more easily. Previously she would suffer for days trying to get up 6 in+ hairballs — now she only feels bad for a little while, still eats her food normally, and her hairballs are much smaller Our vet put our long-haired cat on this high fiber food to help with her massive hairballs.

My big boy cat Baby has had horrible issues with constipation including a clean out visit to the vet. The Royal Canin Gastrointestinal Fiber response veterinary diet has literally been a lifesaver for Baby. He has daily normal poops since he has been on this prescription food. I also feed it to Cleo my 17 year old feline and she too has normal daily poo's...and I also notice their fur is shiny and beautiful. I recommend this to those of you who have cats thqt are constipated. I also commend Chewy for delivering it promptly to my apartment door. I can't say enough good words about Chewy.

I wouldn’t want to get anyone’s hopes up, but my 14 year old Maine coon was dealing with constipation that led to an obstipation and a preliminary diagnosis of mega colon last year. The vet said “wait a minute…I’ve heard this food can make a huge difference”. We tried the food (along with the medications) and within a week my cat was looking much better. More than 6 months later, she’s still on the diet and going strong, the vet credits the diet for saving her life. I’m very glad we were able to get her started on this food!

I have been feeding this to my one cat for about 6 years on the advice of my vet. I realize this next part makes me guilty of being quite foolish and stupid but I only looked at ingredients over a week ago. Am I seeing what I’m seeing just a whole bunch of fillers, by products and items never heard of? I’ve been paying $56 a bag with similar all fillers bags in the grocery store for $10-$15 a bag. Can someone tell me differently and by how? Thank you Respectfully Mr. Michael P.

I've always been skeptical of prescription foods and their contents, and always opted to feed my cats the most holistic diets I could. That said - my cat, who had a previously fractured pelvis from before she found me, who after 10 years of managing chronic constipation recently developed megacolon to a life-threatening degree. I started her on this food, and both our worlds have changed! When things got critical, we were up to two doses of Miralax (r), two doses of lactulose, and 3 doses of cisapride a day. Now that she's on this diet, everything is "smooth" sailing ! I'm so glad she enjoys eating it, because it's been amazing. She's gained her appropriate weight back and she barely needs I've always been skeptical of prescription foods and their contents, and always opted to feed my cats the most holistic diets I could.

No more constipation! For one cat this means $$$$$$$$ in vet bills. Both cats were given a choice of three different kibbles and they both chose this one. My cats are acting like kittens and the one who has problems no longer has a bloated stomach. It is a little pricey but the vet bills are so much worse!

Like many of the other reviewers, my cat suffered from chronic constipation, multiple visits to the vet for enemas and all around stress for him (and me). This food truly made a difference! It's been 5 months and he has had no issues and he "goes" once a day. I can't say enough good things and I want to let others know there is hope!

Got it to see if my senior cat will eat it since there’s no smaller size bag. Very costly purchase for a cat may eat a few kibbles first day and hasn’t touched it since. This rate, the bag may last 10 years to finish up if my 18 years old cat lives that long. At least, my senior cat hasn’t turn his nose completely at it and thought it’s a good sign. Lately, he has not shown any interest. Will try to return if possible or donate.
