Protein Levels In Kitten Versus Adult Cat Food

How Does Cat Food Designed For Adults Affect A Kitten’s Delicate System?

Adult food contains additives like preservatives that kittens’ young bodies may have trouble tolerating. It also has higher mineral levels important for adults but too rich for kittens.
