Q: How old is a 1-year-old cat in human years?
A: About 15 human years. A 2-year-old cat is about 24, and each year after that adds about 4.
Q: How long do cats usually live?
A: Indoor cats commonly live 12 to 18 years. Outdoor cats often have a shorter lifespan because of traffic, disease and injury. These are typical ranges, not predictions.
Q: At what age is a cat considered a senior?
A: Cats are generally considered senior from about 11 years old, and super senior from 15. Regular vet check-ups become especially important at these stages.
