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.

Amazing for my cats skin

My cat had horrible atopic dermatitis on his neck, he would get painful lesions and his skin under his neck was raw from the constant scratching and licking. Medications would help but never fully heal him, the lesions would always come back. This food healed his skin!!! Hasnt had any lesions for a year since we started the food! I am no longer concerned about his quality of life!

My cats love it!

The vet suggested I try this food for my cat while we determine what was cause her allergy. All of our cats LOVE this food!!!! When it turned out that it wasn't her regular food causing the allergy, but her cat treats, they were a bit upset to have to go back to their regular food. Now, we use this food as cat treats. Even though Royal Canin cost more than regular food, it cost way less than cat treats do. Especially since some members of my household tend to feed the cats quite a few treats! :-) Yes, as others have mentioned, the food does have a very distinctive smell. When we were feeding it to them regularly as food I did get used to the smell after a few weeks. It also helped keeping the food sealed, which is always best anyway to keep the food fresh.

Good and Bad

My cat was put on this due to vomiting and diarrhea. Both are gone, but I can barely get her to eat this. As others have said, it smells awful. I am not exaggerating when I say that I can smell it from 10 feet away. I have to keep the bag sealed or it smells up the room. She will only eat it because I won't let her have anything else and she is starving.

Helped my cat with a protein allergy!

I adopted my cat and he had chronic diarrhea, no idea why. Tried over the counter food sensitivities food but nothing worked. Finally vet put him on this food after a couple others and it worked! Apparently he's sensitive to proteins and this food breaks it down enough that he can digest it. Only downside is it smells horrible and it took him a while to get used to the taste (at first he didn't eat very much of it). Plus too expensive!

8 pawsdown!

I have 8 cats. One has yet to be determined allergies (itchy/scratchy). He's been on RC Limited Diet Duck/Green Pea formula for years. The DVM thought maybe Ultamino formula would be better. NOT! First, it smells horrendous. Cats have a keen sense of special & they ALL took one whiff of this food and turned up their noses. Even the feral cat I feed wouldn't eat it! Second, it is only available in a 5.5# bag. If my cats HAD liked the food, it would be cost-prohibitive, as are many of the RC foods but as a pet parent, what other option(s) do I have? If they need a certain food, they need it.

Walter loves it

I bought this about 6 months ago. Walter has IBS and the veterinarian recommended it. It took about 3 weeks and Walter started feeling much better. He doesn't throw up as much as he used to and has started to gain his weight back. This food made a big difference in my cats wellness!

Miraculous

After trying other hydrolized protein feeds, we were were ready to resort to invasive tests to get to the bottom of our cat's colitis. She improved in a day on the Ultamino and was symptom - free in less than a week. And she likes it! Just wish there was a canned version or treats!
