Most cat food manufacturers offer a series of foods that support your cat’s dietary needs throughout the varying stages of her life. Kitten food offers extra protein to support her developing brain and growing muscles and bones. However, when your cat reaches her first birthday, this kitten food provides too many calories and can contribute to obesity. Thus you need to switch to an adult formula food. You can continue with this food for most of your cat’s life but consider switching to an adult or mature formula food once she starts showing signs of aging. There are also specialized foods that help manage specific health issues such as weight control, urinary tract support or hairball control. Some of these foods are only available by prescription. Gradually switch foods over about a week to reduce digestive issues. For more information, contact your veterinarians Green Bay, WI.
