The '''Chinese Hamster''' is a species of [[hamster]], scientific names ''Cricetulus griseus'', which originates in the [[desert]]s of northern [[China]] and [[Mongolia]]. These animals grow to between 7.5 and 9 cm in length and as adults can weigh 50-75 grams. They live two to three years on average. The Chinese hamster is often kept as a pet or (in the past) as a laboratory animal.  
 
  
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).

== History and Origin ==
  
The wild colour is greyish brown above with a black stripe down the spine and a whitish belly. This 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]]s. 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.

Despite the name, the Polish rabbit is thought to have originated in Belgium and has been exhibited in England since 1884. Many believe that they were developed from Dutch and Himalayan rabbits in the 1860s. The Polish rabbit was originally developed as a meat breed and was larger than the contemporary Polish. In the 1900s, the Polish rabbit was one of the most popular meat breeds in Europe, especially [[Belgium]].hi
  
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.

Today, the Polish rabbit is now considered more of a pet and is classified as a fancy breed. They are small rabbits with short ears that touch each other all the way to the tips. Due to their small size, the Polish rabbit is often confused with the Netherland dwarf, although the Polish is a little larger and the head is not rounded. The Polish rabbit weighs about three to four pounds.
  
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.

Until the 1950s, most Polish rabbits were white with either red eyes or blue eyes. The red-eyed white is a true albino. The blue-eyed white has the Vienna white gene and is not a true albino. Since the 1950s, colored Polish breeds have been recognized by rabbit clubs. In 1957, the [[American Rabbit Breeder’s Association]] approved the black and chocolate Polish. In 1982, the blue variety was approved and in 1998 the broken variety was allowed.
  
Of note, some [[US]] states such as [[California]] regard the Chinese hamster as a pest, and as a result require a special permit to own, breed or sell.  Other states such as [[New Jersey]] require a similar permit, in order to prevent the proliferation of non-indigenous animals.

Because of their small size, Polish rabbits need less space in cage and barn facilities, and take up less space in apartments than some of the larger bunnies. As with other small breed rabbits, they tend to be higher strung than their larger counterparts. They are also not ideal pets for small children as they are easily dropped, injured and stepped on. Their high-strung nature makes them more suited for a mature, rabbit-loving, adult home.
There is quite some confusion over the latin name of the Chinese hamster and the closely related [[Chinese striped hamster]]. Some people consider the Chinese hamster (''Cricetulus griseus'') and the Chinese striped hamster (''Cricetulus barabensis'') different species [http://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?mode=Undef&id=10028], whereas others classify them as identical [http://walnut.bioc.columbia.edu/srs7bin/cgi-bin/wgetz?-id+4mKAd1Sl9c0+%5Btaxonomy-ID:10029%5D+-e], the Chinese striped hamster as a subspecies of the Chinese hamster (in which case the latin name of the Chinese striped hamster would be ''Cricetulus griseus barabensis'') [http://www.ratbehavior.org/pet_rodent_classification.htm] or the other way round (in which case the latin name of the Chinese hamster would be ''Cricetulus barabensis griseus'') [http://www.napak.com/chinese_hamster.html].

The Polish Rabbit is a breed of rabbit. It is a compact breed with the reputation for being high-strung. The breed was developed in Belgium as food; however as time progressed, it became more popular as a pet.

History and Origin

Despite the name, the Polish rabbit is thought to have originated in Belgium and has been exhibited in England since 1884. Many believe that they were developed from Dutch and Himalayan rabbits in the 1860s. The Polish rabbit was originally developed as a meat breed and was larger than the contemporary Polish. In the 1900s, the Polish rabbit was one of the most popular meat breeds in Europe, especially Belgium.hi

Appearance

Today, the Polish rabbit is now considered more of a pet and is classified as a fancy breed. They are small rabbits with short ears that touch each other all the way to the tips. Due to their small size, the Polish rabbit is often confused with the Netherland dwarf, although the Polish is a little larger and the head is not rounded. The Polish rabbit weighs about three to four pounds.

Until the 1950s, most Polish rabbits were white with either red eyes or blue eyes. The red-eyed white is a true albino. The blue-eyed white has the Vienna white gene and is not a true albino. Since the 1950s, colored Polish breeds have been recognized by rabbit clubs. In 1957, the American Rabbit Breeder’s Association approved the black and chocolate Polish. In 1982, the blue variety was approved and in 1998 the broken variety was allowed.

Housing and Care

Because of their small size, Polish rabbits need less space in cage and barn facilities, and take up less space in apartments than some of the larger bunnies. As with other small breed rabbits, they tend to be higher strung than their larger counterparts. They are also not ideal pets for small children as they are easily dropped, injured and stepped on. Their high-strung nature makes them more suited for a mature, rabbit-loving, adult home.

Feeding

Commercial rabbit pellets are recommended. Feed 1/4 cup of pellets per 5 pounds of body weight every day. For rabbits under 8 months of age, feed unlimited plain alfalfa pellets. Fresh rinsed greens, vegetables, and fruit, as well as grains and hay, can then be given as supplements. Free choice hay, such as timothy, should always be available and changed daily. Alfalfa hay, which is too rich in calcium, should not be offered free choice to rabbits over 8 months of age.

As with other rabbits, Polish rabbits do not do well in high or low temperatures. They are prone to hairball obstructions and matted coats if not cared for properly. Rabbits need daily grooming to remove loose hair. Other health concerns include earmites, Pasteurella, respiratory disease, dental problems, urinary bladder stones and fractured backs. Be quick to notice any changes in diet or litter box habits and contact a rabbit veterinarian immediately.

The average life span of a breeding Polish rabbit is 5 to 6 years. By spaying or neutering your Polish early in life, you can increase their life expectancy to around 10 years.
