What Is Considered a Senior Cat? Age Stages, Health & Care Guide

According to the American Association of Feline Practitioners (AAFP) and the American Animal Hospital Association (AAHA), a cat is officially considered a Senior Cat when they reach 11 years of age (equivalent to approximately 60 human years). Cats aged 15 years and older are classified as Geriatric (Super-Senior). Knowing your cat's life stage helps you spot subtle aging symptoms and adjust veterinary care to ensure a long, comfortable life.
