...the Government of the United States, which gives to bigotry no sanction, to persecution no assistance, requires only that they who live under its protection should demean themselves as good citizens in giving it on all occasions their effectual support. Geo. Washington Feb. 22, 1732

Toad Tales

From Wikipedia, the free encyclopedia
The Pallas's cat (Otocolobus manul), also called the manul, is a small wild cat with a broad but fragmented distribution in the grasslands and montane steppes of Central Asia. It is negatively affected by habitat degradation, prey base decline, and hunting, and has therefore been classified as Near Threatened by IUCN since 2002.
The Pallas's cat was named after the German naturalist Peter Simon Pallas, who first described the cat in 1776 under the binomial Felis manul                                    


The Pallas's cat is about the size of a domestic cat. ...The combination of its stocky posture and long, dense fur makes it appear stout and plush. 


 Its fur is ochre with dark vertical bars on the torso and forelegs. The winter coat is greyer and less patterned than the summer coat. There are clear black rings on the tail and dark spots on the forehead. The cheeks are white with narrow black stripes running from the corners of the eyes. The chin and throat are also white, merging into the greyish, silky fur of the underparts. 
Concentric white and black rims around the eyes accentuate their rounded shape. The legs are proportionately shorter than those of other cats, the ears are set very low and wide apart, and the claws are unusually short. The face is shortened compared with other cats, giving it a flattened look. The pupils are circular. The short jaw has fewer teeth than is typical among cats, with the first pair of upper premolars missing, but the canine teeth are large. The cheeks are white with narrow black stripes running from the corners of the eyes. The chin and throat are also white, merging into the greyish, silky fur of the underparts.  
...
Pallas's cats are solitary. Both males and females scent mark their territory. They spend the day in caves, rock crevices, or marmot burrows, and emerge in the late afternoon to begin hunting. They are not fast runners, and hunt primarily by ambush or stalking, using low vegetation and rocky terrain for cover. They feed largely on diurnally active prey species such as gerbilspikasvoles and chukar partridges, and sometimes catch young marmots.

Reproduction

The breeding season is relatively short due to the extreme climate in the cat's native range. Oestrus lasts between 26 and 42 hours, which is also shorter than in many other felids. Pallas's cats give birth to a litter of around two to six kittens after a gestation period of 66 to 75 days, typically in April or May. Such large litters may compensate for a high rate of infant mortality in the harsh environment. The young are born in sheltered dens, lined with dried vegetation, feathers, and fur. The kittens weigh around 90 g (3.2 oz) at birth, and have a thick coat of fuzzy fur, which is replaced by the adult coat after around two months. They are able to begin hunting at four months, and reach adult size at six months. Pallas's cats have been reported to live up to 11 years in captivity.
...
The manul has long been hunted for its fur in relatively large numbers in ChinaMongolia, and Russia, although international trade in manul pelts has largely ceased since the late 1980s. About 1,000 hunters of Pallas's cats are in Mongolia, with a mean estimated harvest of two cats per year. Cats are also shot because they can be mistaken for marmots, which are commonly hunted, and trapped incidentally in leghold traps set for wolves and foxes and snares set for marmots and hares. They are also killed by herding dogs. The fat and organs of the cats are used as medicine in Mongolia and Russia. While Mongolia has not recorded any trophy exports, skin exports have grown since 2000, with 143 reported exported in 2007.

Conservation

Otocolobus manul is listed in CITES Appendix II. Hunting of this felid is prohibited in all range countries except Mongolia, where it has no legal protection despite being classified as Near Threatened in the country. Since 2009, the felid is legally protected in Afghanistan, banning all hunting and trade in its parts within the country and is listed as an endangered species in Pakistan-administered Kashmir.

In captivity

In 2010, there were 47 Pallas's cats in 19 institutions that are members of the Association of Zoos and Aquariums, and four litters were expected. No births and three deaths occurred in 2009. Pallas's cats have the highest percentage of 30-day mortality of any small cat at 44.9%. The seasonality of their reproduction makes it difficult to control reproductive cycles. Keeping Pallas's cats healthy in captivity is difficult. They breed well, but survival rates are low owing to infections, which are attributed to an underdeveloped immune system. In their natural high-altitude habitat, they would normally not be exposed to viruses causing infection.
In June 2010, five kittens were born in the Red River Zoo in Fargo, North Dakota. A female was artificially inseminated for the first time at Cincinnati Zoo, and gave birth to three kittens in June 2011. In May 2013, three kittens were born at the Nordens Ark zoo in Sweden.In May 2016, four kittens were born at the Korkeasaari zoo in Finland
