Dietary modification is a cornerstone of chronic vomiting management in cats, with specific dietary approaches appropriate for different underlying causes.
Dietary management for chronic vomiting cats must be matched to the identified or suspected cause to be effective. A hydrolyzed protein diet prescribed for a cat with lymphoma will not address the primary problem; a highly digestible diet alone for a food-allergic cat will not eliminate the allergen exposure causing inflammation. Appropriate dietary modification requires either diagnostic information about the cause or a systematic diagnostic trial that provides that information. The welfare benefit of successful dietary management — elimination of chronic nausea and vomiting — is significant and sustained, making the investment in proper dietary selection worthwhile.
