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

I am very glad this is back in stock as this is an essential food for my medically food sensitive cat. This food is by prescription only and when it was unavailable at most places, the substitute food recommended to me did not work and sent my cat to the Vet, ending in a VERY expensive vet bill. When my vet was unable to see my cat, another veterinary hospital was able to step in and help care for my sick cat. They call this food "the magic poopy food" and it truly is amazing at getting the job done. If your cat experiences severe constipation as mine does, consider asking your vet about this great food. It is a bit expensive but so medically necessary for my cat. I highly recommend this food I am very glad this is back in stock as this is an essential food for my medically food sensitive cat.

I prefer NEVER to have to give my cat dry food but this was recommended to me by my vet at a time when I was ready to try anything because my cat suffers from serious constipation and does not drink water. Luckily even with only 1 small portion a day my cat is more regular and she loves this stuff. I do wish that it would come in smaller bags. 8lbs. is quite a lot of food to buy when you aren't sure if it will work or if your pet will like it. Yes, I would recommend this as a possible help to your cat's constipation.

Both of my cats are going to the bathroom great since use but I had to contact Royal Canin to find out how to ween the cats off the script food they were on to the Royal Canin that does not give those directions on the bag. Email back said give 25% mixed in with what they were on for 3 days, then 50% for 3 days , then they should be ready for it only to eat.

Cat food is good, Thor really likes it and it keeps him healthy. Had a really hard time getting approval to send the food. Spent 4 days going back and forth about the perscription. Had a good perscription that was written in January for unlimited purchase but was rejected for being out of date. Had to go to Vet to get a new perscription but still had a lot of issues with upload and chewy vet approval. Chewy should make this process much easier. We can't get it local and went through a lot of hassle to finally get the food that we were out of.

I began my kitty’s diet change using the Hills Science Diet because the Royal Canin was on back order everywhere & I couldn’t get it. But I noticed immediate changes in her ability to poop regularly. I’ll admit at 1st, I didn’t think I’d be able to get her to eat this. So, like any type of food or diet change, she didn’t take to it immediately. It literally smells like earth (grass & dirt) lol. But I knew it was necessary. So as with any diet change, I began the transition process. I started adding in a small amount of it to her existing food & each day I added a little more of this & a little less regular food. The transition was actually less difficult than I anticipated - my kitty has never I began my kitty’s diet change using the Hills Science Diet because the Royal Canin was on back order everywhere & I couldn’t get it.

So as with any diet change, I began the transition process. I started adding in a small amount of it to her existing food & each day I added a little more of this & a little less regular food. The transition was actually less difficult than I anticipated - my kitty has never & will not eat ANYTHING but water & dry cat food (no wet food, no treats, no people food — NOTHING) & she’s been this way pretty much since birth. So the transition process wasn’t something I was looking forward to. But simply changing to a food that they don’t like or won’t eat right away, will most likely create an aversion to that particular food. So transitioning was key. Plus I didn’t want it to cause stomach upset or anything like that. But anyway, after being on this special food for just a couple of days, I noticed a lot of profound changes in my kitty! 1st, you wouldn’t believe the size of the poop that came out of her, lol! And she’s been able to truly clear herself out tever since! She’s been on this new diet since April 2021 & it’s now mid July 2021. She’s not constantly constipated anymore (poor thing). The vet said that she’s be on this for the rest of her life & now while this is a very expensive food, I don’t mind if it’s improving her quality of life & overall comfort level. Additionally, I noticed profound changes in her overall mood, her energy levels have increased, she’s more playful, she awake a lot more & she’s not as fat either. So this stuff is fantastic! I was informed there is an alternative to this food, it’s from “Hills Science Diet - Gastrointestinal Biome” dry kitty food & it’s offered here & other places too. Now my kitty eats either (surprisingly), but they’re very similar in their ingredients & they even smell the same. I had to buy once because I couldn’t find the Royal Canin anywhere & she had to eat that for a few weeks. But I thought I’d put the info out there so you know there is an alternative. Though it’s certainly a very similar food, it’s not identical. It’s why my vet called it an alternative. I feel the Royal Canin is just a bit better & more effective but my kitty was okay on it for those few weeks. … more

It will take some time before we know the effect of this product. In somewhat of a related review, the cat litter you ship us is to heavy for the box it ships in. It broke through the box on our doorstep. Chewy is doing a great job in helping our cat and many others! Thank You

After reading so many positive reviews I had hope this food would be the miracle cure for my cat who has chronic constipation. After several days of eating it, she has not gone. Glad so many have gotten relief with this food. Unfortunately, it didn’t work for me. Will be returning for full refund.

My cat, Pickles, has had digestive issues since I brought her home from a shelter. She has been to the vet several times and I've tried their suggestions of probiotics, then not giving her treats, hairball formulas, etc... Pickles has not really liked the Royal Canin but I mix it in with her other food. Chewy is the best - very responsive, great selection of pet care products and outstanding customer service. Highly recommend!

My vet and I feel that this Royal Canin Gastrointestinal Fiere Response food is a life saver for my kitty, Tippy, who is now aactually 10 years old. He has been on this diet for about 9 and a half years. So when we could not get this food we tried others that did not do well with his body. So, when you got it back in stock it was quite a relief for me and for Tippy as well. He is now eating, drinking, and eliminating like he did before the food was unavailable. Thank you!!

This Royal Canin gastro formula really works to keep my 3 cats "regular" and producing normal bowel movements. When I ran out and couldn't find this food any more (including from my vet) I had to resort to another brand that my vet recommended. Same cost but not the same results. Chewy came through for me when they were able to get some in stock. The cats are back to their normal selves again and I'm very thankful for Chewy!
