- Abstract
Reproductive data compiled from the International Clouded Leopard Studbook revealed that 75% of all litters were born to females between one and five years of age. Sixty-three percent of the males had sired litters by four years of age with reproduction declining after six years of age. Sixteen zoological institutions surveyed worldwide contributed estrous cycle data from 28 clouded leopards. Sexual maturity (age at first estrus) for these females ranged from 17 to 28 months of age with a mean estrous cycle length of 29.9 ± 13.8 days. The mean length of estrus was six days. Gestation length ranged from 85 to 121 days (X̄ = 93.4 ± 6.3). There was a significantly higher incidence of estrus in fall and winter compared with spring and summer over latitudes ranging from 36°-45° and 51°-55° ( P < .005). Mating occurred in all months except June and October, and cubs were produced in all months except December. The highest frequency of mating occurred during the month of December corresponding with a birth peak in March.
