Why Do Kittens Need a Different Food?

According to the ASPCA, kittens actually have about two to three times more energy than an adult cat. Up to thirty percent of this energy comes directly from the protein in their diet. Overall, this means that a bag of food specially formulated for kittens will require significantly more protein than adult cat food.

This isn’t the only difference in the diet though. Kittens are prone to growing much bigger and at rapid rates during the first year of life.

Growing like this will require them to have more nutrients, protein, and vitamins than an adult cat will really need. The way they grow and metabolize their food is the significant reason why kittens need a different diet than adult cats.
