Rated 5 out of 5 by Stopped Barfing! (knock on wood) My cat has barfed from the time he was a kitten. He is now 8 years old. He barfed almost daily. After numerous visits to the vet and over $1100 in charges to run tests that showed he was perfectly healthy I was at my wits end. I had tried going grain free, limiting his feeding, special dishes to slow down his eating, etc. and the barfing continued. On this last visit the vet prescribed this food (yes it needs a prescription from the vet) as a last-ditch "let's try this and see" attempt to help him. I mixed it 1/2 and 1/2 with the Fromm food I was currently feeding at the time in order to transition him over to the new food and the barfing immediately stopped. My intention was to transition to just this food (as the vet recommended) but the cat seems to be doing fine on the 1/2 and 1/2 mixture. Due to the cost of this, as long as he keeps doing well I will just leave this mixture alone. So far it has been almost 4 weeks and he vomited once and it was just hair. No food came back up. He likes this food. I have 2 other indoor only cats who eat from the same bowl. They all seem happy with it. Definitely worth trying if you have a cat with a chronic vomit problem. I just hope it continues doing such a great job for us. October 17, 2016
Rated 4 out of 5 by Are my cats worth it? I originally had my Ragdoll cat on Orijen cat food. From my research, Orijenis a good product and my cat loved it. However, the cat started having asthma spells and medicine did not improve the condition. This is where the Royal Canine food comes in. The vet thought that maybe a ingredient in the Orijen product (there are many) could be causing a reaction in the cat and suggested trying a hypoallergenic food. I just started giving the cat this food this week, so I can't say yet if it is working in reducing the asthma spells; However, I can say that the cat loves the taste. This is good and bad. The bad is that the cat is eating more and the product is relatively expensive. Almost 1 1/2 times as much as Orijen; BUT if the product helps his asthma spells, then the product may be worth the cost. September 22, 2016
Rated 5 out of 5 by Cat loved it! Internal medicine specialist prescribed this for my cat with food allergies. Cat loves eating it and I love that he can finally be weaned off of his prednisolone. It's a win! October 17, 2016
Rated 5 out of 5 by Amazing food! Before my vet recommended this food, my cat had diarrhea for almost a year, despite trials of many different kinds of special diets, probiotics, canned pumpkin and several prescription drugs, including flagyl, tylan and c-budesonide. Within a few days of switching to this food, the diarrhea went away completely! It's been almost two weeks since she's been on this food, and she's doing great - I love this food! October 12, 2016

Rated 5 out of 5 by He's eating it! Boo has allergies, at times he looks like a hairless cat! Have tried multiple foods; most of which he refuses to eat. The vet recommended This Royal Canin Hydrolized Protein food and he likes it. Victory! October 12, 2016
Rated 5 out of 5 by It's comparable to pizza. My IBD cat eats it as prescribed by our vet. Fortunately my other senior cat likes it a lot too. They both eat it as if I put a pizza pie in front of them. I wish it wasn't so expensive but prescription food is. At least shipping is free and customer service at Chewy is the best. October 6, 2016
Rated 4 out of 5 by Good service and product. This was my first time using online buying for my cat supplies. It came promptly, and the price was good. October 12, 2016
