Changes in your pet's stool color and consistency are normal when pets are transitioning to a fresh diet, especially if they are coming from a dry or canned diet.
During a transition to a fresh diet, the bacteria and nutrients found in the intestinal tract are changing, which means pets may have looser stools and go more frequently as they adjust. You may also occasionally notice some undigested ingredients in their stool. This isn't problematic, and shouldn't prompt concern as there are still plenty of nutrients within the diet.
With time, your pet's stools should become firmer, smaller, and they will likely be going less frequently. This is one of the benefits of a fresh diet. Since Nom Nom only uses whole food ingredients and doesn't include any fillers, your pet can better digest all the nutrients and use most of the food which results in less waste.
