Nutrition of aging cats.
At least one-third of cats seen by veterinarians are mature, defined as 7 years of age or older, and approximately 13% of cats are geriatric, defined as 12 years of age or older. The article reviews physiologic differences between these life stages and relates the changes to nutritional needs. Geriatric cats have increased requirements for dietary energy and protein. Feeding management addresses what, when, how, and where food is provided. This article provides an update on diet-sensitive conditions, including cognitive dysfunction, diabetes mellitus, chronic kidney disease, osteoarthritis, and hyperthyroidism. Although guidelines are provided, patients must be evaluated and fed according to their individual needs.
