Most cat food manufacturers make a variety of foods that will support your cat’s needs during the different stages of her life. Kitten formula food has enough extra protein to support her developing brain and growing muscles and bones. However, by the time your cat is about one year of age, kitten food will provide too many calories and could contribute to obesity. Thus you will need to switch to an adult formula food. You can feed your cat this food for most of her life. When your cat starts showing signs of aging, a mature or senior formula food may be a better choice. There are even foods that support specific health issues such as weight control, urinary system management, allergies, or hairball control. Some of these foods are only available by prescription. Change foods gradually over about a week to prevent digestive issues. For more information, contact your Arlington Heights, TX veterinarian.
