Royal Canin Veterinary - Gastrointestinal Moderate Calorie - cat dry food

These kibbles that I’ve been buying for 5 years suited my two cats very well, as they both have gastrointestinal issues. But in the last bag I bought, the kibbles are different—bigger, lighter in color, and round, whereas they used to be triangular. I feel like my cats are having trouble getting used to them because they’ve been vomiting frequently since. I don’t know if Royal Canin changed the recipe for these kibbles, but just in case, I’m going to try the ones from Hill’s.
