When Do You Stop Feeding Kitten Food

When should you stop feeding kitten food? Kitten food is different than adult cat food because it has higher protein and fat content. It’s important to make sure your kitten gets the right nutrition, but there are some things you need to look out for when switching over from kitten food to adult cat food. Here are four signs that it’s time to switch

  1. Your kitten no longer wants the wet or dry kibble
  2. Your veterinarian recommends a diet change
  3. You notice your pet losing weight even though he/she eats less
  4. You’ve reached one year of age.

When a kitten reaches 16 weeks of age, her nutritional needs change from those of a kitten to that of an adult.  Depending on the breed, she may be completely done growing by 6 months of age, though some kittens do take up to 12 months for their bones to mature.

To understand how big your cat will get as an adult, you need to know how big her parents are.  If she’s a small breed, like a Devon or Cornish Rex, you can expect her to stay on the small side; if she’s a big breed, like a Maine Coon or Norwegian Forest Cat, you can expect her to be on the large size as an adult.

My female cat weighed 10 pounds at her last checkup at age 7.  I was not surprised to learn that she weighed 10 pounds, because she is a very large cat with Maine Coon breed lines.

If you were feeding your kitten the right amount of food for her stage of life (kitten or adult), you can expect her weight to stay steady as an adult.  If she’s a kitten but is putting on weight, then you may need to cut back on the amount of food that you give her.

Changing your cat from a kitten to an adult diet can be accomplished in one step or more gradually over time.

Gradually changing from one type of food to another helps reduce potential digestive upset.  Start by adding a little bit of the new food to your cat’s current diet every day until you’re feeding only the new food.

Your veterinarian will be able to advise you on how much food to feed your adult cat based on her size and activity level.


When should you stop feeding kitten food? The answer to this question is not so simple. For some kittens, the switch from kitten food to adult cat food may be a gradual process that takes place over time while for other cats it could happen quite abruptly without any warning signs.

It’s important to pay attention to your pet and how they’re responding in order to best determine when they are ready for the change.
