How Diet Helps Manage IBD in Cats
Special therapeutic diets reduce gut inflammation by:
- Using highly digestible ingredients (>90–95%) to minimize residue and ease absorption.
- Minimizing antigenic load with hydrolyzed (broken-down) or novel proteins (e.g., rabbit) to avoid immune triggers.
- Lowering fat to reduce pancreatic stimulation (common in IBD + pancreatitis cases).
- Supporting microbiome with prebiotics/probiotics for better stool quality and gut health.
Goals: Fewer vomiting/diarrhea episodes, firmer stools, weight restoration, and improved quality of life. Per experts, dietary trials succeed in 50%+ of cases; combine with meds if needed.
