Abstract |
Noninvasive fecal assays were used to study steroid metabolism and ovarian activity in several felid species. Using the domestic cat (Felis catus) as model, the excretory products of injected [14C]estradiol (E2) and [14C]progesterone (P4) were determined. Within 2 days, 97.0 +/- 0.6% and 96.7 +/- 0.5% of recovered E2 and P4 radioactivity, respectively, was found in feces. E2 was excreted as unconjugated estradiol and estrone (40%) and as a non-enzyme- hydrolyzable conjugate (60%). P4 was excreted primarily as non-enzyme- hydrolyzable, conjugated metabolites (78%) and as unconjugated pregnenolone epimers. A simple method for extracting fecal steroid metabolites optimized extraction efficiencies of the E2 and P4 excretion products (90.1 +/- 0.8% and 87.2 +/- 1.4%, respectively). Analysis of HPLC fractions of extracted fecal samples from the radiolabel-injected domestic cats revealed that E2 immunoreactivity coincided primarily with the unconjugated metabolized [14C]E2 peak, whereas progestogen immunoreactivity coincided with a single conjugated epimer and multiple unconjugated pregnenolone epimers. After HPLC separation, similar immunoreactive E2 and P4 metabolite profiles were observed in the leopard cat (F. bengalensis), cheetah (Acinonyx jubatus), clouded leopard (Neofelis nebulosa), and snow leopard (Panthera uncia). Longitudinal analyses demonstrated that changes in fecal E2 and P4 metabolite concentrations reflected natural or artificially induced ovarian activity. For example, severalfold increases in E2 excretion were associated with overt estrus or exogenous gonadotropin treatment, and elevated fecal P4 metabolite concentrations occurred during pregnant and nonpregnant (pseudopregnant) luteal phases. Although overall concentrations were similar, the duration of elevated fecal P4 metabolites during pseudopregnancy was approximately half that observed during pregnancy. In summary, steroid metabolism mechanisms appear to be conserved among these physically diverse, taxonomically related species. Results indicate that this hormone-monitoring approach will be extremely useful for elucidating the hormonal regulatory mechanism associated with the reproductive cycle, pregnancy, and parturition of intractable and endangered felid species. |

Abstract |
Considerable efforts have been devoted to conserving the snow leopard Panthera uncia in recent years, but progress has inevitably been slow due to the difficulties of studying a sparsely distributed, secretive and endangered species in often isolated mountainous terrain. Although knowledge about the species overall distribution in the highlands of Central Asia still remains fragmenatry, it is important to briefly examine all the available information in order to review measures taken to date to conserve the species through the protected areas network. The purpose of this paper is to examine the distribution and status of protected areas inhabited or visited by snow leopard in relation to the species' distribution and highlight deficiences in the present network. |

Abstract |
For carnivore species, spatial avoidance is one of the evolutionary solutions to
coexist in an area, especially if food habits overlap and body sizes tend to coincide.
We reviewed the diets of two large cats of similar sizes, the endangered snow leopard
(Panthera uncia, 16 studies) and the near-threatened common leopard (Panthera par-
dus, 11 studies), in Asia. These cats share ca 10,000 km2 of their mountainous range,
although snow leopards tend to occur at a significantly higher altitude than common
leopards, the former being a cold-adapted species of open habitats, whereas the latter
is an ecologically flexible one, with a preference for woodland. The spectrum of prey
of common leopards was 2.5 times greater than that of snow leopards, with wild prey
being the staple for both species. Livestock rarely contributed much to the diet. When
the breadth of trophic niches was compared, overlap ranged from 0.83 (weight categories)
to one (main food categories). As these leopard species have approximately
the same size and comparable food habits, one can predict that competition will arise
when they live in sympatry. On mountains, climate change has been elevating the
upper forest limit, where both leopard species occur. This means a habitat increase
for common leopards and a substantial habitat reduction for snow leopards, whose
range is going to be squeezed between the forest and the barren rocky altitudes, with
medium- to long-term undesirable effects on the conservation of this endangered cat |

Abstract |
Two adult snow leopards (Panthera uncia), male and female, both with vaccinations current, became infected with feline panleukopenia virus (FPV) at the Blank Park Zoo, Des Moines, Iowa, in late 1988. Clinical signs included weakness, hemorrhagic feces, fever, seizures, and nasal discharge. Blood analysis revealed severe lymphopenia and mild anemia. A positive enzyme-linked immunosorbent assay (ELISA) test for FPV on fecal contents from the male leopard confirmed the diagnosis. In spite of intensive therapy, both animals died. Necropsy of the female, which survived for 1 wk after onset of signs, revealed intestinal crypt necrosis, pulmonary consolidation, necrotizing laryngitis, and diffuse lymphoid depletion. The male leopard, which lived 3 wk after onset of illness, had similar enteric and lymphoid lesions. In addition, there was a severe interstitial pneumonia, with syncytial cells containing eosinophilic intracytoplasmic inclusion bodies. Ultrastructural characteristics of these inclusions featured tubular structures consistent with a paramyxovirus. Although repeated virus isolation attempts from the affected lung were negative, polyclonal and monoclonal fluorescent antibody tests were strongly positive for canine distemper virus (CDV). Frozen paired sera from each leopard demonstrated very high acute and convalescing titers to FPV; both animals also seroconverted to CDV, with titers in the male leopard higher than those in the female. Additional tests for toxoplasmosis, feline infectious peritonitis, feline rhinotracheitis, feline calicivirus, feline leukemia, canine parainfluenza, and bovine respiratory syncytial virus were all negative. The neurologic signs present in these leopards remained unexplained, but may have been attributable to CDV infection. A feral cat trapped on zoo property had feces positive for FPV by ELISA. Although the specific contributions of FPV and CDV toward the development of this case are unknown, it is likely that initial FPV-induced immunosuppression allowed the subsequent development of CDV in these snow leopards. The likelihood that initial FPV infection came from feral cats underscores the importance of feral animal control on zoo premises. |

Abstract |
The recent development of potent and specifica lphar-adrenoceptoar gonistsa nd antagonists has enhanced their use in nondomestic animal immobilization and reversal. Medetomidine, a new potent alphar-agonist, in combination with the dissociative anesthetic ketamine, has been used to immobilize a variety of nondomestic mammals. Medetomidine alone induces sedation in a dose-dependent way, and complete immobilization has been achieved with high doses in semidomesticated reindeer (Rangifer tarandus) and blue foxes (Alopex lagopus). Howbver, we feel that ketamine should be added to the immobilization mixture to ensure complete immobilization and operator safety. In ketamine combinations, medetomidine doses are usually 60-100 pg/kg. The required ketamine doses are remarkably low:0.8-1.6 mglkg in most ruminants,2.5-3.0 mgUgin felids,u rsids,a nd canids,a nd 5.G-8.0m glkgi n primates,w olverines(Gulog ulo),ando therm uitelids. Clinically, the resulting immobilization is characterized by a smooth onset, good to excellent myorelaxation, and areflexia at higher doses. Determinations of hematologic, serum biochemicil, arterial blood gas,a nd acid-bases tatusp arametersi ndicate that the immobilization is physiologically sound. We have had no fatalities attributable to the immobilization mixture ( I ,240 immobilizations). The alphar-adrenoceptora ntagonist,a tipamezole,i s highly efective in reversingt he immobilization induced by medetomidine, medetomidine-ketamine combinations, or xylazine. In ruminants, the medetomidine-ketamine-induced immobilization can be rapidly and persistently reversed by administering 100-l 50 1rg/kg of alipamezole i.v. and the rest s.c., adjusting the total atipamezole dose to an atipamezole: medetomidine ratio of approximately 4-5 (w/w). Becauseth e required ketamine doses are relatively high in carnivores, we prefer to use a lower atipamezole dose (totil atipamezoie: medetomidine ratio approximately 2-3 w/w) and to administer it i.m. or s.c. Using thii regimen, reversals are calm and animals show minimal “residual ketamine effect.” Because atipamezole is a competitive antagonist, its dose should be reduced if it is administered late in the immobilization period when a large part of medetomidine has been endogenously metabolized. Xylazine-induced immobilization is rapidly reversed by I mg of atipamezole for every 8-12 mg of xylazine used. |
