While a 7-year-old dog might be considered a senior, a 7-year-old cat is only just entering middle age. Cats generally live longer than dogs, with many indoor cats reaching their late teens.
A cat is officially considered a “senior” around age 11, and “geriatric” at age 15. Understanding these life stages helps you adapt their diet and vet visit frequency accordingly.
