The '''Chinese Hamster''' is a species of [[hamster]], scientific name ''Cricetulus griseus'', which originate in the [[desert]]s of Southern [[China]] and [[Mongolia]]. These animals grow to between 7.5 and 9 cm in length and as adults can weight 50-75 grams. They live two to three years on average.
 
  
A Chinese hamster's body proportions, compared with those of other hamsters, appear "long and thin" and they have (for a hamster) a relatively long tail. Chinese hamsters are not, technically, [[dwarf hamster|"dwarf" hamsters]] since this term refers to animals in the genus ''Phodopus'', (the two types of [[Phodopus sungorus|Russian Dwarf Hamster]]s and [[Phodopus roborovski|Roborovskii Dwarf Hamster]]s).
+
'''Roborovskis''' ('''''Phodopus roborovski''''') are the smallest of the [[hamster]]s commonly kept as [[pet]]s; they are also the fastest. They are distinguished by the white spots where their eyebrows would be. On average, they live the longest of any pet hamsters, living about three to three and a half years of age.
  
The wild colour is greyish brown above with a black stripe down the spine and a whitish bellyThis colouration, combined with their lithe build and longer tail, makes them look "mousy" to some eyes and, in fact, they are members of the group called [[ratlike hamster|ratlike hamsters]]. Besides the wild colour, a well-known variation is the white-spotted Chinese hamster, which often is greyish white all over, with only a dark stripe on its back.
+
They are easily startled and are generally quite shy but curiousThey're social and usually sleep together in one place. They aren't good pets for families with children.  They are the world's fastest hamsters.  They're obviously also not a good fit for someone who wants a hamster that they can cuddle. Roborovski's are certainly not cuddlers. They are generally the size of a thumb and can easily squeeze through the bar of the cage, so careful consideration of cage choice is important. Because of their size and speed, Roborovski's are best for people who prefer to observe rather than to play with their pet.
  
They have quiet temperaments and are easily handled; one of their endearing traits is that of clinging to a finger with all four paws, rather like a harvest mouse on a corn stalk. Chinese hamsters can be quite nervous as youngsters but, once they are tame, display an endearing calmness and gentleness of character.
+
When observed they can be hilariously funny as they can often be seen scrapping. When they sleep, the fully grown ones are usually about the size of a ping pong ball. If kept together in mixed sex pairs or groups Roborovski Hamsters usually start to breed in the Spring following the year in which the female was born. Females often become sterile at around 24 months of age but males usually remain fertile for most of their life.
  
In the past, Chinese hamsters were commonly used [[Experimental_animal|laboratory animals]], until they were replaced by the common mouse and rat, which are easier to keep and breed. However, quite a few biotech drugs are still being produced by putting the gene for the protein into [[Chinese_Hamster_Ovary_cell|Chinese hamster ovary (CHO) cells]], which then produce the protein.

Roborovski hamsters are usually only pregnant for 23-30  days. When the young are born that usually look like beans. At around 5-6 days the skin may start to pigment and at 6-8 days hair begins to emerge and by 10-12 days the babies are covered in short fur and the eyelids are developing. At this time the babies may also start wandering around the cage, even though still blind. The female will usually collect the wandering babies and return them to the nest - this may be accompanied by squealing from the babies but is not usually anything to worry about. At 14-16 days of age the eyes open and the babies are covered in fur.

Roborovskis (Phodopus roborovski) are the smallest of the hamsters commonly kept as pets; they are also the fastest. They are distinguished by the white spots where their eyebrows would be. On average, they live the longest of any pet hamsters, living about three to three and a half years of age.

They are easily startled and are generally quite shy but curious. They're social and usually sleep together in one place. They aren't good pets for families with children. They are the world's fastest hamsters. They're obviously also not a good fit for someone who wants a hamster that they can cuddle. Roborovski's are certainly not cuddlers. They are generally the size of a thumb and can easily squeeze through the bar of the cage, so careful consideration of cage choice is important. Because of their size and speed, Roborovski's are best for people who prefer to observe rather than to play with their pet.

When observed they can be hilariously funny as they can often be seen scrapping. When they sleep, the fully grown ones are usually about the size of a ping pong ball. If kept together in mixed sex pairs or groups Roborovski Hamsters usually start to breed in the Spring following the year in which the female was born. Females often become sterile at around 24 months of age but males usually remain fertile for most of their life.

Roborovski hamsters are usually only pregnant for 23-30 days. When the young are born that usually look like beans. At around 5-6 days the skin may start to pigment and at 6-8 days hair begins to emerge and by 10-12 days the babies are covered in short fur and the eyelids are developing. At this time the babies may also start wandering around the cage, even though still blind. The female will usually collect the wandering babies and return them to the nest - this may be accompanied by squealing from the babies but is not usually anything to worry about. At 14-16 days of age the eyes open and the babies are covered in fur.
