Evaluation of management in North American zoos to enhance breeding success of the fishing cat (Prionailurus viverrinus) ex situ population

The ex situ population of fishing cats (Prionailurus viverrinus) face many challenges to its sustainability such as mate incompatibility, low founder numbers and disease prevalence. The North American population was monitored for a three-year period during institutional transfers and breeding introductions. In total, 26 fishing cats, including 15 different breeding pairs were monitored during 20 […]

The influence of olfactory enrichment on the behaviour of captive black-footed cats, Felis nigripes

The value of olfactory enrichment for captive-housed animals is now well recognised. Large cats have been shown to benefit from the introduction of odours to their captive environment, but to date the effect of odour introduction on the behaviour of small cats remains unknown. This study investigated the behaviour of six zoo-housed black-footed cats, Felis […]

Restoration of reproductive potential after expiration or removal of melengestrol acetate contraceptive implants in Tigers (Panthera tigris)

Abstract 10.1002/zoo.20137.abs The need for contraception in the successful management of captive wild animals is becoming increasingly apparent. Because concerns exist regarding the reversibility of the contraceptive implant melengestrol acetate (MGA), reproductive data for 94 female Amur (Panthera tigris altaica) and Sumatran tigers (Panthera tigris sumatrae) were analyzed using survival analyses to evaluate return to […]

Seminal and endocrine characteristics of male Pallas’ Cats (Otocolobus manul) maintained under artificial lighting with simulated natural photoperiods

Abstract 10.1002/zoo.20127.abs Pallas’ cats (Otocolobus manul) have a pronounced reproductive seasonality controlled by photoperiod. Previous studies of reproduction in captive Pallas’ cats exposed to natural light showed a breeding season of December–April. This study evaluated the impact of artificial lighting timed to simulate natural photoperiods on male reproductive seasonality of four Pallas’ cats housed indoors. […]

An unusual osteological formation in the posterior skulls of captive tigers (Panthera tigris)

Abstract 10.1002/(SICI)1098-2361(1998)17:23.3.CO;2-3 Examination of pathologies in a series of felid skulls from a museum collection spanning the past century revealed distinctively malformed external occipital protuberances in zoo specimens of Panthera tigris, a condition that was not present in the skulls of wild-caught individuals. Myological studies and comparative dissections together support a conclusion that the condition […]

Reassessing the relationship between juvenile mortality and genetic monomorphism in captive cheetahs

Abstract 10.1002/(SICI)1098-2361(1996)15:43.3.CO;2-O Low levels of genetic heterozygosity are commonly considered a major threat to the survival of wild and captive populations. However, intense focus on genetic issues may obscure the importance of extrinsic factors influencing species’ survival in wild and captive environments. A key example for this is the cheetah (Acinonyx jubatus), which is frequently […]

Fecal androgen metabolite analysis for noninvasive monitoring of testicular steroidogenic activity in felids

Limited data are available on long-term, seasonal changes in testicular steroidogenic activity in nondomestic felids, primarily because of the difficulties associated with longitudinal blood sampling (e.g., handling, restraint, anesthesia). Therefore, a noninvasive approach for assessing testicular androgen production was developed using the domestic cat (Felis catus) as a model. Two adult males were injected i.m. […]

Successful ovulation induction and laparoscopic intrauterine artificial insemination in the clouded leopard (Neofelis nebulosa)

Abstract 10.1002/(SICI)1098-2361(1996)15:13.3.CO;2-J Exogenous gonadotropins and a laparoscopic intrauterine artificial insemination (AI) technique were assessed for effectiveness in the clouded leopard (Neofelis nebulosa), a species difficult to breed in captivity due to severe mate incompatibility. Fourteen hormone trials using 10 female clouded leopards were performed to evaluate the ability of 50, 100, or 200 i.u. pregnant […]

Cortisol metabolism in the domestic cat and implications for non-invasive monitoring of adrenocortical function in endangered felids

Abstract 10.1002/(SICI)1098-2361(1996)15:13.3.CO;2-Q Three domestic cats were given i.m. injections of 3H-cortisol to determine the time course and relative proportion of excreted 3H-cortisol metabolites into urine and feces. Most urinary radioactivity was detected in the first sample collected at 3.9 ± 2.5 hr postinjection and accounted for 13.9 ± 2.1% of the total radioactivity recovered. High […]
