These rodents are discovered in a wide range of habitats, from northern Europe within a broad band across a great deal of Asia, apart from the southeastern corner. Twenty-four species are identified but, as in the gerbils, only one particular – the Golden, or Syrian, Hamster (Mesocricetus auratus) – has turn into common as a pet all through the globe.

The Golden, or Syrian, Hamster

The Golden Hamster was initially discovered in 1839 and, forty years later, live specimens had been brought to England from Syria by James Skene, who had been serving there within the diplomatic service. This group appears to possess thrived for thirty years, with all the final progeny dying in 1910.

Subsequently, there appears to possess been none of those rodents in captivity till April, 1930. Certainly, it was recommended that the species was extinct, until Dr. Israel Aharoni found a nest of Syrian Hamsters on Mount Appo in Syria. The young hamsters were transferred to the Hebrew University at Jerusalem. The breeding program was not completely prosperous at first, due to the fact four from the eight hamsters escaped, and then a female died as a result of a fight using the only surviving male. From this unpromising starting, however, the male mated successfully with both the other females and, within a year, 3 hundred and sixty-four offspring had been reared.

A number of the progeny had been sent to Dr. Edward Hindle in England and, possibly by means of breeding stock in the London Zoo, Golden Hamsters became available for the pet-owning public. It was not till the commence with the Second World War that these hamsters had been observed alive in North America. It is remarkable to reflect that all such hamsters kept throughout the world currently are believed to be the direct descendants from that nest discovered on Mount Appo more than half a century ago.

Hibernation

An uncommon and typically disconcerting habit of hamsters is their capacity to hibernate if environmental situations are unfavorable. This is a natural trait, which to some extent is now much less apparent in domesticated stock. The hamster’s physique temperature falls from the typical amount of about 37 C (98.7 F) to somewhat above the environmental temperature. The respiratory price is barely one breath a minute, whereas below normal situations the figure reaches as much as one hundred or a lot more. Because the heart beat may also be as low as four contractions per minute, compared with five hundred per minute inside the active animal, towards the casual observer a hibernating hamster appears dead. A fall in temperature, coupled with declining periods of light, will trigger hamsters to enter this torpid state.

Clearly, within a area in the residence heated for the duration of cold climate, such behavior is less probably to take place. To encourage a hibernating hamster to wake from its sleep, transfer it to a warm position exactly where it might awake gradually. A temperature in excess of 20 C (68 F) is excellent. Steadily the hamster’s breathing will grow to be apparent, and its body will warm up as blood flow to the skin increases. In the event you find out a hamster apparently dead in the nest, treat it in this solution to establish regardless of whether or not it has merely entered a torpid state.

Other factors also influence a hamster’s readiness to enter a state of dormancy. These consist of the provision of a very deep layer of bedding material and, substantially, an chance for the hamster to store food. Hoarding behavior is pretty organic, with food becoming taken back within the cheek pouches and stored inside the nest.
