【 摘 要 】

References(16)Cited-By(9)The breeding season was investigated in 174 female cats that were acclimated under a natural photoperiod, and determined the interval between birth and initial estrus (puberty) was determined in 125 cats. Although the breeding season differed noticeably among individual animals, the mean was 180.4 ± 3.0 (SE) days between the end of January and the end of July. The interval between birth and first estrus ranged from 181 to 560 days, with a mean of 345.0 ± 0.9 days. With respect to month of birth, the mean interval was 343.0 ± 9.5 days in cats born between March and June. Among cats that were born between July and October, the mean intervals were 242.0 ± 6.3 days in cats that exhibited estrus the year after birth and 519.2 ± 5.8 days in those that exhibited estrus 2 years after birth.
