Age is not just a number in this case

When it comes to choosing the diet for your cat, age is not just a number, because you have to consider its needs at every stage of its life. For instance, if you want to adopt a kitten then you have to choose a diet rich in essential nutrients because they have different needs than an adult cat. 

“Just as human babies don’t eat the same foods as adult humans, nor should kittens and adult cats eat the same foods since they require different nutrients as they change over the years. You may see cat food with the phrase ‘for all life stages’ in its description, but it’s best to seek life-stage nutrition,” says Brittany Carey, a cat specialist, and manager at Cat Safari in San Francisco.
