While most pets adapt easily to a raw food diet, some may experience challenges during the transition period. During the first 2 to 4 weeks of transitioning, pets may experience digestive upset, including gas, loose stools, and in rare cases, vomiting. This happens because the enzymes necessary for digesting high-quality protein in raw diets differ significantly from those needed for high-carbohydrate, processed foods. The body must adjust to producing the appropriate enzymes, and because raw food has a high moisture content (65%–75%), it requires less bile for digestion.
