Most cat food manufacturers offer foods that provide the proper nutrition for different stages of your cat’s life. Kitten formula food provides extra protein to support your cat’s growing brain, muscles and bones. However, when your cat reaches about one year of age, her kitten food has too much fat for her adult body and can lead to obesity. Thus you will need to change to an adult formula food. Your cat will eat adult food for most of her life. When she starts showing signs of aging such as mobility or digestive issues, you may need to change to a senior or mature formula food. There are also foods that help manage specific health issues such as weight reduction, urinary issues or hairball control. Some of these foods are only available through prescription. Change foods slowly over a period of at least a week to avoid digestive issues. Learn more from your qualified vets Colorado Springs CO.
