Cats with sensitive stomachs need a diet that minimizes digestive upset while providing complete nutrition. Our team compared dozens of formulas, focusing on single-source proteins, limited ingredients, and added prebiotics. We looked for foods that could be fed as a complete diet for adult cats with frequent vomiting, diarrhea, or gas. In our evaluation, we considered fat content (lower is generally easier to digest), fiber sources (soluble fibers like beet pulp are gentler), and the absence of artificial additives. Our picks come from reputable brands with long track records in sensitive diet formulations.
