Cat Age Calculator

Cats don't age ×7 — the first year alone is worth about 15 human years. Pick the breed and we'll add that breed's lifespan and senior threshold.

How the math works

A cat reaches roughly 15 human years by its first birthday and about 24 by its second, because kittens grow up far faster than children. After that, every cat year adds around four human years. So a 10-year-old cat is about 56 — middle-aged, not elderly — and a 20-year-old cat is about 96.
