摘要: Based on the Chiang's method, life table for cats was constructed from death data of 3936 cats. They died in Kanto area and were buried an animal cemetery Tokyo June 1981 through May 1982. This seems to be first one domestic pet The expectation 4.2 years at age 0, 5.0 1, 5.4 4, 5.3 5, 3.5 10, 2.2 15. maximum 22 years. From 0 probability dying higher than that dogs, but over 6 it seemed Gompertz's equation applicable this these results, if early ages decreases, fundamental pattern curve a similar figure dogs. different breeds localities. Comparing 1 (e1) two populations divided by or localities, there significant difference e1 among localities not breeds. These facts suggest existence some factors which may influence span
