Lanier, D. L., & Dewsbury, D. A. (1976). A quantitative study of copulatory behaviour of large Felidae. Behavioural-Processes, 1(4), 327–333.
Abstract: Observed a total of 109 copulations in 6 male-female pairs from 4 species of large Felidae. The mean intromission durations were 3.0 sec for Asian leopards (Panthera pardus), 3.3 sec for African leopards (P. pardus), 12.9 sec for snow leopards (Uncia uncia), 2.3 sec for spotted jaguars (P. onca), 3.3 sec for black jaguars (P. onca), and 12.4 sec for Siberian tigers (P. tigris). Behavioral patterns were qualitatively similar across species; all displayed a copulatory pattern with no lock, no intravaginal thrusting, ejaculation on a single insertion, and multiple ejaculations. Whereas domestic cats are reported to assume a neck grip and to tread prior to insertion, these larger Felidae generally did so after intromission had been achieved. After copulation, females of some pairs swiped at the male and displayed a rolling after-reaction. (18 ref) (PsycINFO Database Record (c) 2000 APA, all rights reserved)(unassigned)

Bannikov A.G. (1971). Genus Panthera.
Abstract: It gives the description of genus Panthera: lion, tiger, leopard, jaguar and snow leopard. The mountains of Central Asia and South Siberia limit the habitat of snow leopard in the USSR. This species is also distributed in the Himalayas, Tibet, and mountains of Mongolia. In summer, it lives at 3,660 3,970 m above sea level, while in winter, following the ungulates; snow leopard descends to 1,800 m. In the Himalayas, it ascends up to 5,500 m above sea level in summer. In Djungar and Talas Ala-Tau, snow leopard keeps at 600 1,200 m. It takes refuge in caves and cracks of rocks. Snow leopard is mostly active in twilights and night, rarer in daylight, and preys on ungulates, hares, marmots, and others. The coupling period is winter or early spring. A gestation is about 90 days. It has 3 5 cubs in a litter.
