Helps reduce skin reactions that may be due to sensitivities to common proteins found in pet foods

Minimizes the risk of reaction with proteins extensively broken down to a size that’s virtually unrecognizable by the immune system

Reinforces the skin barrier with specific nutrients to support healthy skin in cats with skin sensitivity and irritation

Helps support healthy digestion with an exclusive blend of fibers

Your vet may have put your cat on an elimination diet trial to test for food sensitivities. Or they believe your cat needs long-term support for their skin issues. In any case, your vet recommended Royal Canin Ultamino for a reason. This innovative diet is the result of years of extensive research, formulated as a nutritional solution for pets with severe food sensitivities. Its highly palatable formula contains a protein source that is broken down to an amino acid level so it can be absorbed in the digestive tract with reduced risk of triggering an immune response. Optimal amounts of B vitamins and amino acids reinforce your cat’s skin barrier. Omega-3 fatty acids EPA and DHA help promote healthy skin and coat. And Relative Supersaturation (RSS) methodology helps reduce the risk of struvite and calcium oxalate crystal and stone formation in the bladder. An exclusive blend of fibers helps support healthy digestion in cats prone to digestive upsets, including diarrhea. And with strict manufacturing procedures to help avoid cross contamination, you can confidently feed Royal Canin Ultamino to your cat for a happy, healthy life.

No more vomiting!

Our cat has been on this over a year now and she is so much better. We tried other foods and nothing worked. She prefers this to anything else, and even after losing many of her teeth she eats it just fine. She doesn't throw up anymore and she feels much better!

Cat likes it and has solved most allergy issues

Our vet had us put our cat on this food and it has solved the vomiting issues! We are still working on scratching and skin reactions but has worked so far to atleast reduce the itch. She eats it no problem just wish we could have a wet food and or treat option for our girl.

Great for Gastrointestinal Issues

My cat has been on this diet for 6 months now and it is the only food that prevents him from vomiting! I just wish it came in a larger bag.

The only try cat food we purchase

Our calico cat, Cali has a severe are auto immune disease and this is the only dry food she doesn't get a severe reaction to. She was a rescue and needs special attention. She loves this food and it helps her live a normal life. This little lover deserves the best!

Helped heal my cat with food allergies!

We used Ultamino exclusively for just over a year while trying to figure out why our cat was having major skin issues. We eventually narrowed it down to food allergies, and I credit our use of Ultamino for helping to get our Autumn's face healed. It helped when all the medications couldn't. I only wish it was a bit cheaper so we could have left all of our cats on it long term. It was truly life-changing for our girl.

Excellent cat food!

My cat has been on ultimino dry cat food for about 2 years. She was extremely allergic to all other cat food. She was on steroids for her constant break outs. But, now that she’s on ultamino dry food, she’s doing good! Haven’t had to give her a steroid in 4 months! I wish there was a canned ultamino I could give her too. Also, her coat looks awesome! No shedding!

Cat actually likes it!

My poor foster cat has food allergies, so her animal dermatologist prescribed this food. She can be particular about food, but she really likes it! My other foster kittens like it too when they steal if from her. Thanks for making a prescription food that helps her.

Best food for tummy problems

My cat has IBDS. It took us a long time to find the right food for her. After living through diarrhea and vomiting for a year, the vet out her on Ultamino. It is the only food we can feed her. She is now healthy and happy. Royal Canin rocks!!!
