猫的年龄怎么换算成人的年龄？How do cat years convert to human years?
常用的换算（International Cat Care 和 AAFP 生命阶段指南采用）是：第 1 年约等于人的 15 岁，第 2 年再加 9 岁（约 24 岁），此后每年约加 4 岁。这只是粗略对照，个体差异很大。The common scale used by International Cat Care and the AAFP life-stage guidelines: the first year ≈ 15 human years, the second adds 9 (≈ 24), then about 4 per year. It is only a rough comparison; individual cats vary.
生命阶段怎么划分？How are the life stages defined?
参照 AAFP/ISFM 的划分：幼猫 0–6 个月，青年 7 个月–2 岁，成年 3–6 岁，壮年 7–10 岁，老年 11–14 岁，高龄 15 岁以上。这些岁数指“几岁”（满 2 岁到 3 岁生日前仍算 2 岁），所以本工具写成连续的区间：幼猫 0–6 个月，青年 7 个月至未满 3 岁，成年 3 岁至未满 7 岁，壮年 7 岁至未满 11 岁，老年 11 岁至未满 15 岁，高龄 15 岁及以上。Following the AAFP/ISFM stages: kitten 0–6 months, junior 7 months–2 years, prime 3–6, mature 7–10, senior 11–14, geriatric 15+. Those ages are whole years (a cat is still 2 until its third birthday), so this tool uses the matching continuous bands: kitten 0–6 months, junior 7 months to under 3 years, prime 3 to under 7, mature 7 to under 11, senior 11 to under 15, geriatric 15 and over.
