Nutrition at Every Life Stage Pets’ dietary needs change as they grow. First, puppies and kittens require nutrient-dense foods to support rapid development. Specifically, they need higher levels of protein, fats, and essential vitamins. Moreover, proper nutrition supports brain and bone growth. Next, adult pets need balanced meals that maintain energy without promoting weight gain. At the same time, portion control becomes increasingly important. Likewise, consistent feeding schedules help regulate metabolism. Finally, senior pets often benefit from diets that support joint health and digestion. For instance, some older pets need fewer calories but more fiber. In contrast, others may require therapeutic diets for medical conditions. Therefore, routine nutrition reviews are beneficial.
