Cat age in human years, by breed
Every cat ages on roughly the same curve. What changes by breed is how many years they get — from about 8 years at the low end to 20 at the high end.
Each page below pairs the human-years chart with that breed's published lifespan, the age it becomes a senior, and the specific inherited conditions that shape its later years.
