My IBD cat won't eat Royal Canin duck. Is Natural Balance LID okay?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Longhair | Female | spayed | 10 years and 5 months old | 10 lbs

My cat has been to the vet twice for vomiting. It is most likely that she has IBD. The vet has prescribed Royal Canin Selected Protein Duck, but kitty wont eat it. I found Natural Balance Limited Ingredient Diet Duck and Green Pea, which she likes better. Is this food a good alternative to Royal Canin? I just want her to eat. She keeps losing weight

I am sorry to hear about Kitty, that sounds so frustrating! So unfortunately the over the counter diets with limited ingredients are not as good as the prescription diets. The reason for this is that the over the counter foods are processed in the same facitilities and sometimes the same equipment as other foods, so some cross contamination does occur. In some pets the small contamination might not be a big deal, in others is can. Think of people with a severe peanut allergy that can't eat anything that says "processed in a plant that also processes peanuts". When they have done studies checking the foods, they can detect other ingredients in those foods. I would let your vet know that Kitty doesn't like the Royal Canin diet. There may be other prescription diet options available from your vet, or your vet may feel comfortable trying the Natural Balance diet in her situation.
