Abstract |
There are several felidae amongst the numerous endangered species. Means of aiding survival are the reintroduction to the wild of animals bred under the auspices of man and their relocation from densely populated to thinly populated areas. It is unlikely that the dangers of such reintroduction or relocation projects have been examined sufficiently in respect to the risks of virus infections confronting individuals kept in zoos or similar situations. This report presents infections may be expected to occur when relo- three examples to illustrate that accidental virus cating and reintroducing wild cats. The first example is the reintroduction of captive snow leopards. Zoo bred snow leopards may be infected with FIV, a virus infection that is highly unlikely to occur in the original hirnalayan highlands of Tibet and China. A second example is of several cases of FIP that occured in European wild cats bred in groups in captivity. The third example mentioned is the relocation of hons from East Africa where all the commonly known feline viruses are wide-spread to the Etosha National Park. In the latter, virus infections such as FIV, FCV and FPV do not occur. The indiscriminate relocation and reintroduction of the wild cats mentioned here harbours a potential of undesirable consequences. |

Abstract |
An extraction and assay procedure to measure fecal estradiol-17-beta and progestin concentrations in several cat species was developed and validated for use for noninvasive monitoring of ovarian function. Fecal samples were collected over a range of 3-20 months from female tigers (three), lions (three), snow leopards (three), cheetahs (two), caracals (two), and domestic cats (five). Samples were extracted with 90% methanol, lipids removed with petroleum ether, and the estradiol and progestins in the methanol measured by radioimmunoassay (RIA). High Performance Liquid Chromatography (HPLC) fractionation and subsequent RIA of the fractions indicated that the estradiol-17-beta antiserum cross-reacted primarily with estradiol-17-beta in the feces of lions and tigers and was assumed to be specific for estradiol-17-beta in the feces of other species as well. However, there were several immunoreactive compounds, presumably progesterone metabolites, excreted in the feces which varied both quantitatively and qualitatively among species. The behavior of tigers, lions, cheetahs, and caracals was visually monitored during the collection period and frequency of sexual behaviors was positively correlated with increases in fecal estradiol in all species observed. The mean fecal estradiol-17-beta peaks were as follows: tigers, 128.0 +- 13.1; lions, 186.0 +- 14.8; snow leopards, 136.7 +- 15.9; cheetahs, 140.9 +- 9.0; caracals, 24.5 +- 4.0; and domestic cats 158.9 +- 19.3 ng/gm. Fecal progestin concentrations rose significantly (P lt 0,001) only after breeding or during pregnancy and were as follows: tigers, 5.6 +- 0.6; lions, 1.9 +- 0.1; cheetahs, 8.4 +- 1.1; and caracals, 2.4 +- 0.4 mu-g/gm. Fecal progestins were elevated for one-half to two-thirds of the gestation length during presumed pseudopregnancy but remained elevated throughout successful pregnancies. These results suggest that ovarian function can be monitored noninvasively in the family Felidae by the measurement of fecal estradiol-17-beta and progestin concentrations. |

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) |
