Hamsters
Hamsters are rodents (order Rodentia) belonging to the subfamily Cricetinae, which contains 19 species classified in seven genera.Fox, Sue. 2006. ''Hamsters''. T.F.H. Publications Inc. They have become established as popular small pets. The best-known species of hamster is the golden or Syrian hamster (''Mesocricetus auratus''), which is the type most commonly kept as pets. Other hamster species commonly kept as pets are the three species of dwarf hamster, Campbell's dwarf hamster (''Phodopus campbelli''), the winter white dwarf hamster (''Phodopus sungorus'') and the Roborovski hamster (''Phodopus roborovskii''). Hamsters are more crepuscular than nocturnal and, in the wild, remain underground during the day to avoid being caught by predators. They feed primarily on seeds, fruits, and vegetation, and will occasionally eat burrowing insects. Physically, they are stout-bodied with distinguishing features that include elongated cheek pouches extending to their shoulders, which ...

Roborovski Hamster
The Roborovski hamster (''Phodopus roborovskii''), also known as the desert hamster, Robo dwarf hamster, or simply dwarf hamster, is the smallest of three species of hamster in the genus ''Phodopus''. It lives in the deserts of Central Asia, averaging under at birth and and during adulthood. Distinguishing characteristics of the Roborovskis are eyebrow-like white spots and the lack of any dorsal stripe (found on the other members of the genus ''Phodopus''). The average lifespan for the Roborovski hamster is 2–3 years, though this is dependent on living conditions (extremes being four years in captivity and two in the wild). Roborovskis are known for their speed and have been said to run up to 6 miles a night. Distribution and habitat Roborovski hamsters are found in desert regions, such as the basin of the lake Zaysan in Kazakhstan and regions of Tuva, Mongolia and Xinjiang in China. The hamsters inhabit areas of loose sand and sparse vegetation and are rarely found in areas o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syrian Hamster
The golden hamster or Syrian hamster (''Mesocricetus auratus'') is a rodent belonging to the hamster subfamily, Cricetinae. Their natural geographical range is in an arid region of northern Syria and southern Turkey. Their numbers have been declining in the wild due to a loss of habitat from agriculture and deliberate elimination by humans. Thus, wild golden hamsters are now considered endangered by the International Union for Conservation of Nature. However, captive breeding programs are well-established, and captive-bred golden hamsters are often kept as small house pets. Syrian hamsters are larger than many of the dwarf hamsters kept as pocket pets (up to five times larger), and weigh about the same as a sugar glider, though the wild European hamster exceeds Syrian hamsters in size. They are also used as scientific research animals throughout the world. Characteristics The size of adult animals is around long, with a lifespan of 2–3 years. Body mass is usually in th ...

Campbell's Dwarf Hamster
Campbell's dwarf hamster (''Phodopus campbelli'') is a species of hamster in the genus ''Phodopus''. It was given its common name by Oldfield Thomas in honor of Charles William Campbell, who collected the first specimen in Mongolia on July 1, 1902. It is distinguished from the closely related Djungarian hamster as it has smaller ears and no dark fur on its Crown (anatomy), crown. Campbell's dwarf hamster typically has a narrow Primitive markings#Dorsal stripe, dorsal stripe compared to the Djungarian hamster and grey fur on the stomach. This hamster may be raised in captivity and kept as a small pet. In the wild, the breeding season for Campbell's dwarf hamster varies by location. For example, the breeding season begins towards the middle of April in Tuva and towards the end of April in Mongolia. However, in captivity, there is no fixed breeding season and they can breed frequently throughout the year. Females are usually sexually mature at two months of age and the gestation pe ...

Winter White Dwarf Hamster
The winter white dwarf hamster (''Phodopus sungorus''), also known as the Russian dwarf hamster, Djungarian hamster, striped dwarf hamster, Siberian hamster, or Siberian dwarf hamster, is one of three species of hamster in the genus ''Phodopus''. It is ball-shaped and typically half the size of the Syrian hamster, so is called a dwarf hamster along with all ''Phodopus'' species. Features of the winter white hamster include a typically thick, dark grey dorsal stripe and furry feet. As winter approaches and the days shorten, the winter white dwarf hamster's dark fur is almost entirely replaced with white fur. In captivity, this does not usually happen as animals maintained as pets are generally housed indoors and exposed to artificial light that prevents the recognition of short winter daylengths. In the wild, they originate from the wheat fields of Kazakhstan, the meadows of Mongolia and Siberia, and the birch stands of Manchuria. Winter white dwarf hamsters are common as pets in ...

Phodopus
''Phodopus'', a genus of rodents in the hamster subfamily Cricetinae—a division of the larger family Cricetidae—is a lineage of small hamsters native to central Asia that display unusual adaptations to extreme temperatures. They are the only known hamsters that live in groups and, in some cases, rely on significant contributions by males to the raising of offspring. They are nocturnal and active throughout the year; they do not hibernate. Species of ''Phodopus'', together with members of the genera ''Cricetulus'', ''Allocricetulus'' and ''Tscherskia'' are called dwarf hamsters because of their small size (roughly ) relative to other hamsters. Like other hamsters, members of ''Phodopus'' have a round body shape, short tails and cheek pouches in which they can store food. They all live in dry conditions with extreme temperatures. They inhabit the forests, steppes and semi-deserts of Mongolia, Siberia, China and Kazakhstan. Fossils of ''Phodopus'' have been found in Pleistocene ...

Small Pet
The most common rodents kept as household pets are hamsters (golden hamsters and dwarf hamsters), gerbils (Mongolian jirds and duprasi gerbils), common degus, fancy mice, fancy rats, common chinchillas, and guinea pigs (cavies). The domestication of small mammals is a relatively recent development, arising only after large-scale industrialization. Historically, Western society was more agrarian than today, with rodents as a whole seen as vermin that were carriers for disease and a threat to crops. Animals that hunted such pests (e.g. terriers and cats) were prized. Some of these small rodents are prohibited from being kept as pets in certain areas for being invasive; California, Hawaii, and New Zealand have strict regulations to protect their native environments and agricultural operations. Gerbils, degus, and domesticated rats have various prohibitions on their ownership. Characteristics Guinea pig Guinea pigs (cavy) have perhaps been kept the longest as pets amon ...

Cricetus
The European hamster (''Cricetus cricetus''), also known as the Eurasian hamster, black-bellied hamster or common hamster, is the only species of hamster in the genus ''Cricetus''. It is native to grassland and similar habitats in a large part of Eurasia, extending from Belgium to the Altai Mountains and Yenisey River in Russia. Historically, it was considered a farmland pest and had been trapped for its fur. Its population has declined drastically in recent years and is now considered critically endangered. The main threats to the species are thought to be intensive agriculture, habitat destruction, and persecution by farmers. Description The European hamster has brown dorsal fur with white patches. The chest and belly are black. The tail is short and furred. It is much larger than the Syrian or dwarf hamsters, which are commonly kept as pets, and is the largest known species of hamster. It weighs and can grow to long with a tail of . Its dental formula is . Behaviour T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cricetulus
''Cricetulus'' is a genus of rodent in the family Cricetidae (voles and hamsters); it has seven member species that inhabit arid or semi-arid regions in Eurasia. They tend to be more ratlike in appearance than typical hamsters, hence the common name ''ratlike hamster''. Many of the species are considered dwarf hamsters. However, members of the genera ''Allocricetulus'', ''Tscherskia'', and '' Cansumys'' are often called ''ratlike hamsters'', and so are considered to be members of the genus ''Cricetulus'' by many authorities. Species *''Cricetulus alticola'' — Tibetan dwarf hamster *''Cricetulus barabensis'' — Chinese striped hamster *''Cricetulus griseus'' — Chinese hamster *''Cricetulus kamensis'' — Kam dwarf hamster *''Cricetulus lama'' — Lama dwarf hamster *''Cricetulus longicaudatus'' — long-tailed dwarf hamster *''Cricetulus migratorius'' — grey dwarf hamster *''Cricetulus sokolovi'' — Sokolov's dwarf hamster See also * ...

Cheek Pouch
Cheek pouches are pockets on both sides of the head of some mammals between the jaw and the cheek. They can be found on mammals including the platypus, some rodents, and most monkeys, as well as the marsupial koala. The cheek pouches of chipmunks can reach the size of their body when full. Description and function Cheek pouches are located in the thickness of the flange on both sides of the head of some mammals. Monkeys have open cheek pouches within the oral cavity, but they open out in some rodents of America. Hence the name "diplostomes" is associated with them, which means "two mouths." In some rodents, such as hamsters, the cheek pouches are remarkably developed; they form two bags ranging from the mouth to the front of the shoulders. Étienne Geoffroy Saint-Hilaire described that some bats of the genus '' Nycteris'' have an amazing form of cheek pouches, as they have a narrow opening, through which the bat can introduce air, closing the nasal canal through a special mecha ...

Mesocricetus
''Mesocricetus'' is a genus of Old World hamsters, including the Syrian or golden hamster, the first hamster to be introduced as a domestic pet, and still the most popular species of hamster for that purpose. Recent research has shown that, unlike almost all other land mammals studied, all species of this genus lack the capacity for color vision.
