Cat owners may need to change a cat's food for a variety of reasons. Changing cat foods should not be done abruptly as this may cause the cat to become ill or reject the new cat food.
Changing cat foods is recommended when the cat reaches a new stage in life. For example, kittens are fed kitten food until they are switched to adult food at about nine months of age. Senior cats are often switched to senior cat food which has more fiber and fewer calories than regular adult cat food.
There may be times when the cat owner's budget may necessitate changing cat foods. A veterinarian may recommend a change in cat food for health reasons.
