Cat age calculator
A two year old cat is 24 in human years. The ×7 rule calls her 14, which is the gap between a teenager and a cat in her prime.
The first year adds about 15 human years, the second adds 9, and each year after adds 4. Enter an age and a breed: the calculator places the result on that curve, then on a life-stage chart drawn from breed lifespan data.
