Assumptions and limits

A chart-based analogy, not a biological-age test or lifespan forecast. Interpolation between listed ages is a calculator assumption.

Chart: 1 month → 1; 3 months → 4; 6 months → 10; 1 year → 15; 2 years → 24. After 2 years: H = 24 + 4(a − 2).

A 5-year-old cat gives about 36 human-equivalent years; a 6-month-old kitten gives 10.
