Any idea when this will be available again?
Answer by CrisFeb 25, 2022
So I went online (not through the app) and they have different size bag options there. I was able to order it that way. Hope this helps.

I have one cat who has been prescribed this food. Is it safe for my other cat who has no issues? He is male and I worry. Unfortunately they have grown up eating with each other and it's extremely difficult feeding them separately. Thank you!
Answer by ChewyMay 28, 2019
As this is a prescription food formulated to meet specific diet restrictions from known health issues, this food should not be fed to any other animal than the one prescribed due to the restriction of specific nutrients. Prescription diets can be detrimental to an otherwise healthy pet if that pet doesn't have the ailment for which the food is designed.

Is this food for cats with IBD and Oxalate crystals?
Answer by ChewySep 26, 2017
This food is formulated with low molecular weight peptides to support skin and digestive health in cats with food sensitivities. It also prevents the development of both struvite and calcium oxalate crystals that form urinary tract stones.

What is in the natural flavors?
Answer by ChewyJan 12, 2021
The natural flavorings come from the ingredients themselves along with the fats and oils.

It's not hyperbole, folks!!!

This food is literally the only thing my "Patootie" can eat. And that's not hyperbolic... it's the truth, plain and simple. What's scary is, when this food is out of stock, Patootie's health goes into decline. I wish there wasn't such a dependency; but he suffered for years, with HORRIBLE "inflammatory bowel disease", before figuring out the cause of it. Once we found Ultamino, it was clear it was THE cure to his ailments. We even tried Royal Canin's "Hydrolyzed Protein" (which is a step below the Ultamino), as we have other kitties who respond well to that; however, Patootie showed only a tad of improvement on the HP. If you're lucky enough to grab this, whenever it's in stock, then good for you! I was finally able to do so, and I'm SUPER relieved! My little guy gets instant relief from the severe food-intolerance, by which he's plagued, that reeks havoc upon his lower-gastrointestinal system. It's AWFUL trying to remedy his symptoms, to no avail, when we know he just needs his Ultamino. I know there are plenty of other folks, who are going through this same frustration, worrying while knowing their feline friend is suffering. I hope all this insanity ends soon and the world gets its normalcy returned. I'm hoping for the best!

The only thing that works for my cat with severe food allergies!

I've tried every other high-quality brand and even the Royal Canin Hydrolized Protein, and this food is the ONLY thing that works for my cat with severe food allergies. Her allergies mainly manifest with severe skin itching, to the point that she licks herself raw and has sore patches all over herself. Some diarrhea also. When this comes back in stock, I buy multiple bags so that she never runs out. It's expensive but definitely worth it!!!

Fast delivery!

I am impressed with the quick delivery of products from Chewy! Even though Chewy reps must check prescriptions from vets for certain foods, the orders are always filled quickly and are very much appreciated!

Lifesaver!!

This prescription food has been a lifesaver for my cat. He has digestive issues and this works great. My only complaint is Royal Canin is out of stock quite often so in turn so is Chewy, It’s a great food.

Pukey no more

I have a cat. She throws up. A LOT. My vet insisted it was her food but my cat is so picky and refused every other food we offered for years. I kept taking her to the vet. The vet would treat her and suggest new food. I would try new food. My Torti would then go on a food strike until I caved and gave her the old food. And round and round we would go. I finally found this food and decided to try it. My cat FINALLY ate it but grudgingly & only after a 12 hour standoff with lots of reproachful stares from her. She stopped puking but still refused to eat very much. She's an old girl and my husband felt bad so he gave her some of her old food. She pigged out... then puked 4 times that day and twice the next. She's back on this food now and eating it much better (maybe she learned a lesson?). She still gets suborn once in a while about eating it but she's MUCH better & the pukiness is basically resolved. This is life with a Torti just in case you were wondering. She's currently happily sleeping on my feet though; she's worth every penny.

stinky but works

The Vet prescribed this food and when I opened the bag the smell was horrible! I thought maybe there was something wrong with the food, but no, it just smells like that. It worked great to help my 3 cats stop vomiting 2-3 times a week. Now it's just hairballs. One problem at a time.

Royal Canin Veterinary Diet

All three cats did not like this item. I decided to mix in some formerly used dry food to give them a chance to eat it. Little by little it is starting to work! It was rather expensive for 5 pounds, so I have no choice to see if they eventually like it!

A nice, clean backside!

My 4yr old cat started have chronic diarrhea issues and frequent hairballs in March 2020. Tests came back normal. We tried so many different prescription diets and single protein diets. Some made things worse, some made it better temporarily but he would relapse. I was at my wit's end, so stressed out and anxious and constantly having to wipe my long haired cats bum. Then my new vet recommended this food and said a lot of pets had success with it when nothing else worked. Y'all, his diarrhea was gone WITHIN THE WEEK. It's been 5 months now and he hasn't had a SINGLE episode of diarrhea or a hairball. It's a miracle. I could cry. He will stay on this food as long as possible. Thank you Royal Canin for making my kitty happy again!

Life saver

My poor Jazzy. She was so sick. Our vet put her on this to decifer if she had food allergies or something worse. She healed and is thriving on this food.

If your cat has a food allergy this is the ticket!

My cat was 4 years old and gradually started vomiting his food after eating. I took him to the vet and after quite a few Veterinary exams, X-rays, bloodwork and then a food trial. We figured it out. Now no more vomit all over my house. He has stopped vomiting all together. He ate some pretty spendy food prior like taste of the wild, Wellness, Fromm. This food is spendy but if you've checked all the other things with your vet this may be the way to go. Ive had lots of cats in my life but this is my first food allergy cat to date.
