Abstract: Spontaneous occurrence of toxocariasis (Toxocaracati) in captive snow leopards with symptoms of diarrhoea, general malaise, letherapy, dehydration, partial or complete anorexia, vomiting with or without expulsion of the ascarid is reported. Response to anthelmintic drug pyrantal pamoate along with antibacterial drug sulphadimethyl pyrimidine and supportive therapy is recorded.

Abstract: In the spring of 1983 the San Francisco Zoo received a female snow leopard (Panthera uncia) as part of an exotic animal exchange program with the People's Republic of China. Upon examination, it was found that this nine-yea old, seventy-five pound, wild-trapped animal had sustained considerable dental injuries, including fractures of all maxillary and mandibular anterior teeth. The purpose of this paper is to describe the dental procedures undertaken to restore the physiological function of all four canines.

Abstract: The methods to obtain progeny of the snow-leopard (Panthera uncia uncia) in captivity were being elaborated in the zoological garden of Kaunas, Lithuanian SSR. The blood characteristics for snow-leopards is given and compared to that for African lions and Sumatran tigers. A series of internal, external and clinical indices is established. The rut lasts for 5-7 day, the duration of pregnancy equals 98 days. The duration of lactation varies from 3 to 4 months. Sexual maturity is attained on the 3rd-4th year. From 1960 to 1967 in zoological ghardens of the world abuot 29 snow-leopards were born. 14 of them -- in the Kauna zoological garden.

Abstract: The snow leopard is listed as endangered, although most of its high mountain habitat remains untouched. However the ability of humans to exploit wildlife has led to it being endangered. Serious attempts to keep snow leopards in captivity began in 1891, but it was not until the 1950s that cubs survived long enough to become breeders. The American Zoo and Aquarium Association (ASA) Snow Leopard Species Survival Plan (SSP) was set up in 1984, achieving success with breeding goals.

Abstract: Eight adult pairs of snow leopards (Panthera uncia) were observed for one to three years in the months December through March to determine the species' social and reproductive characteristics in captivity. To statistically examine the occurrence of behaviors as a function of estrus, the observation weeks were divided into three time blocks: before estrus, estrus, and after estrus. Using percentage of scan samples as an estimate of time spent in various behaviors, 16 behaviors and combined behavior categories were examined for (1) behaviors that differentiated successfully from unsuccessfully breeding pairs, (2) sex differences in behavior, (3) significant correlations between pair members, and (4) behaviors that showed time block effects. The rationale for identifying a behavioral profile of successful breeders in snow leopards was to aid zoos in their captive management programs by increasing their knowledge of the social behavior of this species. By finding correlates to breeding success, informed decisions on whether to change partners after a certain period of time, how to group the cats, and the optimum strategy for a survival plan can be made.
