Simplified “cat years ↔ human years” estimate
Choose direction, enter one number, then Calculate
Pick cat years → human years or human years → cat years. Cat→human follows a common simplified curve (first cat year ≈15 human years, second adds ≈9, then ≈4 per cat year); human→cat applies the inverse of that same curve. Decimal cat ages (e.g. 2.5) are interpolated inside each segment. This demo caps entries at 38 cat years or 120 human years for stable output—not a clinical model.
No. It is a simplified chart for curiosity only. Inputs cap at 38 cat years and 120 human years; breed and health change real aging.
