At what age is a cat considered senior?

According to AAFP life stage classifications, 7-10 years is the mature stage, 11-14 years is the senior stage, and 15+ years is super senior. Cats 11 and older are generally considered senior, and biannual comprehensive checkups are recommended.

How old is a 1-year-old cat in human years?

A cat's first year is equivalent to approximately 15 human years, the second year adds 9 more (about 24 human years), and each subsequent year adds roughly 4 human years. So a 5-year-old cat is about 36 in human years, and a 10-year-old is about 56.
