Worked wonders for my IBD Kitty!

I received my first bag of this just over a month ago and it has been a life saver! My just turned 2yr old kitty was diagnosed with IBD and it has been miserable to control. We have tried so many prescription foods with little to no success until we found this! Meow Meows IBD was so bad that he was throwing up even while he was on medication and already on another brand of hydrolyzed food. Once I switched to this his throwing up not only stopped but he is almost completely weaned off the medication also! I cannot say enough good things about this after the success I have had with it. We literally had nothing left to do for my poor guy and having to give him meds daily was making him even more miserable. So happy to have found Royal Canin Hydrolyzed Protein, it literally saved my little guys life and I cannot give enough thanks!

Changed kitty's life!

My sweet 1.5 year old calico had chronic cat acne on her chin and also had eosinophilic granuloma complex,often on her lips. Her vet aid it could possibly be a protein allergy and suggested a specialized protein diet. I read all the amazing reviews on the Royal Canin site for this food and decided to try it. Twelve weeks later and not a single outbreak! This food is amazing. Thank you Royal Canin!

Saved my cats life

My cat Bear was horribly sick growing up. He never seemed to put on weight and was constantly having turds randomly pop out of his butt (he was as surprised as I was). He originally was diagnosed with IBS. I switched him to this amazing food immediately and he gained weight, his skin stopped flaking, and no more surprise turds! I came to find out recently he has nerve congenital nerve damage in his back end making his intestines not work properly. This food is pure magic. You get what you pay for! Although I do wish it was not as expensive for this broke college kid;)

IBD Cat Healthy and Comfortable

We inherited a family cat who had had diarrhea for about as long as we had known him. At approximately 10 years of age he had watery diarrhea and had been losing weight over the past two years. We first tried the novel protein approach, which seemed to help a little but not significantly. We then tried prednisolone and another brand of hydrolyzed protein diet. This was the best combination yet, but he still had quite loose stools and obvious times of discomfort when he would posture and vocalize his pain. We tried to keep his interest in his canned food and pred by sprinkling another kind of hypoallergenic food on top of his dish, but that food was unavailable for several weeks. Our vet said that Royal Canin also made a hydrolyzed protein diet, so we might try that instead. I gradually began adding Royal Canin to his regular food and when we ran out of the other two brands he received only Royal Canin HP. After 3-4 days I observed him pass the first formed stool he has had in perhaps 5 years or more. After 2 weeks his stool is even more normal and he no longer has any episodes where he looks uncomfortable. It is a miracle! We worked with different diets for almost 4 months and found this one by chance. He was always an affectionate cat, but now he follows us around all day and wants to be held constantly. He is more laid back and clearly so grateful to be comfortable. His coat looks great, he has continued to gain the weight he lost over the past two years and now feels a little round when I pick him up. I encourage owners to explore other hypoallergenic diets and not assume they are all alike. Although this food is expensive it is the only thing that we have found that works for our kitty and so it is priceless!

My Cat is Going to Live!

I was really worried about my kitty who seems to be allergic to most meat proteins. This food has saved her life. She likes the taste and even though it is soya based, it is balanced nutrition. My friends say she is the most well groomed cat the seen. My vet was pleased with her check up. I only hope one day they come up with a canned version and possibly more hydrolyzed meats and flavors, but for now I am pleased.

Healed My Kitties Paws

Best Cat food ever! My cat loves it and it has healed the issues he has had with his paws for years now. I just wish it came in a wet food option as well. The dogs have a wet option, Don't understand why the cats don't.

Expensive, but good for kitty’s IBD

But this food every time now, even with change to their formulation. Expensive, but good for kitty’s IBD. Otherwise pukes up other foods.

A finicky cat loves the taste...I love the benefit

My cat is an extremely finicky eater, so I was worried when my veterinarian recommended this food to help control her weight. My veterinarian gave me suggestions on how to phase in this food, and within a week, my cat was eating this food over her previous non-Royal Canin dry food, and even over her favored wet cat food! My cat is almost through her second bag of the Feline Hydrolyzed Protein HP dry cat food, and she still loves it. At first I thought the price of the large bag was rather high, but when I found out how many recommended servings were in each bag, this product was worth every penny! My cat has maintained her weight, and she is happy with the taste and serving size of the product. Additionally, this diet seems to be easy on her stomach. I am pleased to have this healthy product to feed my cat. I am happy to highly recommend the Royal Canin brand to other pet owners.
