Sloane, A., Kelly, C., McDavitt, S., & Marples, N. (1998). Big cats in captivity: a quantitative analysis of enrichment. Adv.Etho, 33, 43.
Abstract: Studies on three species of big cats at Dublin Zoo have led to firm conclusions about the effects of certain forms of enrichment, some of which will be presented here. Lions, jaguars, and snow leopards were studied over two years and their behaviours quantified using focal animal sampling during selected hours during daylight. By comparison of these activity budgets with and without the enrichments being present, it was possible to identify the exact behavioural changes caused by each enrichment method, and to quantify these changes. In this contribution we present results showing that the presence of a platform in both lion and jaguar enclosures dramatically reduced stereotypic pacing behaviour. We will demonstrate that the effects of short term enrichment devices may have a wide range of effects on behaviours which outlast the presence of the stimulus. For instance scents added to the cage, or food/play items such as horse hides, hidden fish or ice-blocks often reduce pacing and increase resting later in the day, even after the cats have ceased using the enrichment items. This reduction in pacing and increase in resting time often meant that the amount of the enclosure used per hour was actually reduced with the presence of new stimuli, as result opposite to what might have been expected. The results of these studies will be discussed in relation to effective animal management.

Abstract: China may hold a greater proportion of the global snow leopard Panthera uncia population than any other country, with the area of good quality suitable habitat, estimated at nearly 300,000 km2, comprising .50% of that available across the species' entire range. We can now reconfirm the presence of snow leopard in the Taxkurgan area of Xinjiang Province in north-west China after a period of 20 years.

Abstract: Summary
A leiomyoma of the urinary bladder in a 14-year-old female snow leopard exhibiting bloody vaginal discharge was removed by partial cystectomy. Gravel (struvite) was found in the urine of the inflammatory bladder. Additionally ovario-hysterectomy was performed. Histological findings showed a glandular-cystic hyperplasia. Tumors of the bladder are very rare in cats. Specifically the benign tumors of the bladder very often have no clinical relevance and rarely result in bladder dysfunction. Therefore they might remain undiagnosed in many cases, particularly since the diagnostic procedure in big cats is very extensive. Leiomyoma of the bladder in snow leopards have not been described yet. The present paper describes the surgery performed, the succeeding therapy, the struvit prophylaxis, and discusses the aetiology of the leiomyoma's origin on the basis of current literature. Zusammenfassung
Bei einer 14-j„hrigen Schneeleopardin mit blutigem Vaginalausfluss wurde ein Leiomyom der Blase durch partielle Zystektomie entfernt. Im Urin und in der entzndeten Blase konnte Grieá (Struvit) nachgewiesen werden. Gleichzeitig wurde eine Ovariohysterektomie durchgefhrt. Der histologische Befund ergab eine glandul„r-zystische Hyperplasie des Endometriums. Tumoren der Harnblase sind bei Katzen sehr selten. Vor allem benigne Blasentumoren haben oft keine klinische Relevanz und fhren selten zu Blasenfunktionsst”rungen. Es ist daher m”glich, dass sie insbesondere bei Groákatzen wegen der aufwendigen Diagnostik bersehen werden. Leiomyome in der Blase sind beim Schneeleoparden bisher nicht beschrieben. In diesem Artikel werden die durchgefhrte Operation, die folgende Therapie und Struvitprophylaxe beschrieben sowie m”gliche Žtiologien der Entstehung des Leiomyoms anhand der Literatur diskutiert.

Abstract: The first observation of the occurrence of multiple ocular coloboma (MOC) in a snow leopard was reported in the International Pedigree Book of Snow Leopards Volume I in 1978 (1). The lesions in this syndrome consist of coloboma of the upper eye lid and uveal coloboma of the globe. Even colobomatous retinal cysts and retinal dysplasia have been noted. The ethiology of in all ten cases of MOC in the snow leopards kept at the Helsinki Zoo were described and discussed in detail in Volume II of the International Pedigree Book of Snow Leopards (2,3). Three cases of MOC in the snow leopards kept at Henry Doorly Zoo, Omaha, Ne., have been described by Phillips (4), one case is known of in Amsterdam (van Bree, personal communication), and two cases in Zoo Zurich (Isenbugel and Weilenmann, pers. comm.) The ethiology of the defect is still not known although various theories ranging from genetic to exogenous factors have been presented.

Waits, L. P., Buckley-Beason, V. A., Johnson, W. E., Onorato, D., & McCarthy, T. (2006). A select panel of polymorphic microsatellite loci for individual identification of snow leopards (Panthera uncia)
(Vol. 7).
Abstract: Snow leopards (Panthera uncia) are elusive endangered carnivores found in remote mountain regions of Central Asia. New methods for identifying and counting snow leopards are needed for conservation and management efforts. To develop molecular genetic tools for individual identification of hair and faecal samples, we screened 50 microsatellite loci developed for the domestic cat (Felis catus) in 19 captive snow leopards. Forty-eight loci were polymorphic with numbers of alleles per locus ranging from two to 11. The probability of observing matching genotypes for unrelated individuals (2.1 x10-11) and siblings (7.5x10-5) using the 10 most polymorphic loci was low, suggesting that this panel would easily discriminate among individuals in the wild.
