The Difference Between Kitten’s Food And Adult Cat’s Food

Adult cat food and kitten’s food don’t differ only in price. Kitten’s food is specifically designed for cats at this particular phase of their life. I mean, you can clearly read on the label that this food is for growth and reproduction while the box of food for adults states that it is for “adult maintenance.” 

Think of it as having a new human baby, their food is different than ours. Also, their nutrition needs are different than that of an adult man or woman. The same goes for a kitty, they have different needs for this phase of their life.

These foods are well studied and tested several times as well. So you can trust them with nurturing your little kitty. Regarding the ingredients, kitty food and adult food differs a lot in the proportions of proteins and fats they contain. For example, Kitten food must have at least 22% protein and 8% fat.

On the other hand, Adult cat foods have to be of 18 % protein and only 5 % fat, as claimed by the U.S. Food and Drug Administration. Indeed, the extra amino acids and essential fatty acids are included to help your little one with healthy tissue growth.

If your kitty doesn’t get enough protein, it won’t grow properly; on the other hand, adult cats don’t need this extra nutrient in their diet.

Also, your kitty is in a growing phase, you should pay attention to its bones and teeth growth. Your kitty also should be supported with Vitamins and Minerals, so it grows stronger, and you won’t have to face health problems in the future. Thus, kitten food is well enriched by it.

For example, we find that kitty food contains a lot of calcium and phosphorus because it is essential for them. On the other hand, we notice that adult cat food does not contain the same amount of vitamins and minerals simply because they no longer need to grow anymore.

If we are talking about calories, kittens need a lot. So, your little kitty needs more than double the amount of calories an adult cat needs due to their excessive energy and playfulness. Indeed, you can guess this from the boxes of kitty’s food. In these special food made for kitties, you can see that there is an increased amount of proteins and fats that is necessary for kittens.

This will give your kitty extra calories. No worries, these excess amounts of calories will ensure that your kitty will grow in excellent health.

Plus, these increased amounts of protein, fat, and calories are the ones responsible for your little one’s energy. On the other hand, if you constantly feed your adult cat kitty food, then your cat may get obese and face complications related to this problem such as heart diseases.

How To Shift From Kitty Food To Adult Food?

Now that you are aware of when can kittens eat adult cat food? You should know about how to transition from the kitty food to adult one.

Obviously, this cannot happen overnight, for that it may cause digestive problems to your adorable kitty. Therefore, it is highly essential that you shift gradually from a kitty’s diet to an adult one.

As you know, your little kitty’s stomach is filled with bacteria and yeast that help it to keep digesting the food it consumed and keep the immune system healthy. And because cats are not like humans concerning food consumption, they cannot switch from one diet to another every day or suddenly.

They consume one type of diet with the same essential ingredients for an extended period. In effect, the sudden switch in their diet may cause a lot of trouble for your kitty, including vomiting and diarrhea.

Because over this specific period, cats develop particular bacteria and yeast to digest their diet, when you suddenly switch what they were consuming, their system will not have time to adjust the bacteria as fast.

Therefore, it is highly recommended that you do a slow transition from kitty food to adult cat food. Generally, the transition should be done in 7 days.

However, it is better if you consult your vet, as diet transition may differ from one breed to another. Nevertheless, here is an alternative plan that is quite successful as reported by many pet parents who have altered their kitty’s diet to an adult one:

  1. Day 1 and day 2, add in your kitty’s dish quarter (¼) of the new diet (adult cat food) to three quarters (¾) of the old diet that you already use.
  2. Days 3 and 4, fill your kitty’s dish with half (½) of the new diet to half (½) of the old diet.
  3. Days 5 and 6, start to add three quarters (¾) of the new diet to a quarter (¼) of the old diet.
  4. Day 7, transition entirely to the new diet and add the full amount of adult cat food your kitty needs.
