Based on the Chiang's method, the life table for cats was constructed from the death data of 3936 cats. They died in the Kanto area and were buried in an animal cemetery in Tokyo from June 1981 through May 1982. This life table seems to be the first one for domestic pet cats. The expectation of life for cats was 4.2 years at age 0, 5.0 years at age 1, 5.4 years at age 4, 5.3 years at age 5, 3.5 years at age 10, and 2.2 years at age 15. The maximum age at death was 22 years. From age 0 to age 5, the probability of dying for cats was higher than that for dogs, but over 6 years of age it seemed that Gompertz's equation was applicable to this life table for cats. From these results, if the probability of dying for cats at early ages decreases, the fundamental pattern of dying curve for cats seems to be a similar figure of dogs. The life table was constructed for different breeds and localities. Comparing the expectation of life at age 1 (e1) of the two populations divided by breeds or localities, there was significant difference in the e1 among different localities but not among different breeds. These facts suggest the existence of some factors which may influence the life span of cats among different localities.
基于蒋氏方法，利用3936只猫的死亡数据构建了猫的生命表。这些猫在关东地区死亡，并于1981年6月至1982年5月被埋葬在东京的一个动物公墓中。这个生命表似乎是国内宠物猫的第一个生命表。猫在0岁时的预期寿命为4.2岁，1岁时为5.0岁，4岁时为5.4岁，5岁时为5.3岁，10岁时为3.5岁，15岁时为2.2岁。死亡的最大年龄为22岁。从0岁到5岁，猫死亡的概率高于狗，但6岁以上时，似乎冈珀茨方程适用于这个猫的生命表。从这些结果来看，如果猫在幼年时死亡的概率降低，猫死亡曲线的基本模式似乎与狗的相似。针对不同品种和地区构建了生命表。比较按品种或地区划分的两个人口群体在1岁时的预期寿命（e1），不同地区的e1存在显著差异，但不同品种之间没有。这些事实表明，不同地区存在一些可能影响猫寿命的因素。
