The '''Syrian Hamster''' or '''Golden Hamster''', ''Mesocricetus auratus'', is the best known member of the [[rodent]] [[subfamily]] [[Cricetinae]], the [[hamster]]s. They may now be [[extinct]] in nature, but are popular as house pets all across the world, and are also used in scientific research. Adults grow from 12.5 to 17.5 cm (5 to 7 inches) in length, and in captivity will usually live from 2 to 3 years.

'''Fancy mice''' ("fancy", in this context, means "hobby") are domesticated versions of the common or house mouse (''[[Mus musculus]]'').
Like most members of the subfamily, the Golden Hamster has expandable cheek pouches, which reach from its cheeks to its shoulders.  In the wild, hamsters are [[larder hoarding|larder hoarders]], and they use their cheek pouches to transport food to their burrows.  They can load a remarkable amount of food into their pouches; their name in the local [[Arabic language|Arabic]] dialect in the area where they are found translates as "father of saddlebags" &#1571;&#1576;&#1608; &#1580;&#1585;&#1575;&#1576;.  If food is plentiful, they will store it in large amounts, and it has been reported that 25 kg of grain was found in the burrow of a single hamster.

Fancy mice are approximately 16-18 cm long from nose to the tip of the tail, and weigh about 35 g for females and 50 g for males. As fancy mice have a different process of [[natural selection]] than their wild cousins, they come in a variety of colors and patterns. Most fancy mice tend to be black, brown, or white in their primary color, but others (blue, champagne, white-[[albino]], chocolate, cream, dove, fawn, lilac, red, silver, or cinnamon) in color are available. Female mice are called ''does'' and males are called ''bucks''.
  
Most hamsters in American and English pet stores are Syrian Hamsters. ''Teddy Bear'' is a term sometimes used for the longhaired variety of the Syrian Hamster, and the so-called ''Black Bear'' hamster is just a Syrian Hamster with black fur. All of them may well indeed be the descendants of a single mother.

==Mice as pets==
 +
Mice are kept as pets in many countries for a number of reasons. Fancy mice are small, inexpensive, clean, and generally have a good [[temperament]]. Female mice are more popular with many owners since they tend to cohabitate with other mice better than males. Additionally, the urine of female fancy mice does not contain as strong of an odor as that of the male mice. Bucks will fight with each other, unless they were introduced at a very young age, and they produce urine with a strong, musky smell. Some people, however, prefer the personality and curiosity of male mice. It is a good idea to keep fancy mice in pairs if possible, since they are sociable animals. However, if a buck and a doe of breeding age are put in the same cage they will keep reproduce every three weeks until separated.  
  
Golden Hamsters have been used in scientific research, in the study of many diseases, and also in the study of behaviour.  They have a number of [[fixed action pattern]]s that are readily observed, including scent-marking.

Mice should be kept in well-ventilated areas. Fish tanks or cages with bars and plastic flooring make good housing.

In [[1839]] [[Britain|British]] [[zoologist]] [[George Robert Waterhouse]] reportedly found an elderly female hamster in Syria, naming it ''Cricetus auratus,'' the Golden Hamster. The hamster's fur was on display at the [[British Museum (Natural History)]].  The Syrian Hamster was then ignored by European science for the next century. Around 1930, zoologist and Professor at the University of Jerusalem [[Israel Aharoni]] found a mother and litter of hamsters in the [[Syria]]n desert. By the time he got back to his lab, most had died or escaped. The remaining hamsters were given to the [[Hebrew University of Jerusalem]], where they were successfully bred. They were a bit bigger than the ones Waterhouse found, so they were named ''Mesocricetus auratus'', though they were thought to be the same as the original hamster, the latin name for which was given to the [[Rennets]]. ''Mesocricetus auratus'' is the currently accepted scientific name of Syrian Hamsters.

Food for fancy mice is relatively inexpensive. Veterenarians generally recomend a product called ''lab block,'' a scientifically-formulated blend originally desinged for mice in laboratories. Dry [[dog food]] is another good option when lab block is unavailable, as it offers balanced nutrition for a mouse and helps keep their teeth conditioned. In order to keep variety in their diets, mice can also eat oats, oily seeds, clean [[egg shell]], breakfast cereal, and stale [[bread]]. They should also have clean water at all times and some sort of chewing wood in order to keep their teeth from growing too long.  
  
Descendants of these hamsters were shipped to scientific labs around the world, for use as research animals. They arrived in the [[United Kingdom]] in 1931, and in 1938 reached the United States. Just about all Golden Hamsters are descended from the original litter found in Syria, except for a few that were brought into the United States by travellers who found them in the desert. A separate stock of hamsters was imported into the US in 1971, but it isn't known if any of today's North American pets are descended from them.

White fancy mouse

Fancy mice ("fancy", in this context, means "hobby") are domesticated versions of the common or house mouse (Mus musculus).

Physical description

Fancy mice are approximately 16-18 cm long from nose to the tip of the tail, and weigh about 35 g for females and 50 g for males. As fancy mice have a different process of natural selection than their wild cousins, they come in a variety of colors and patterns. Most fancy mice tend to be black, brown, or white in their primary color, but others (blue, champagne, white-albino, chocolate, cream, dove, fawn, lilac, red, silver, or cinnamon) in color are available. Female mice are called does and males are called bucks.

Mice as pets

Mice are kept as pets in many countries for a number of reasons. Fancy mice are small, inexpensive, clean, and generally have a good temperament. Female mice are more popular with many owners since they tend to cohabitate with other mice better than males. Additionally, the urine of female fancy mice does not contain as strong of an odor as that of the male mice. Bucks will fight with each other, unless they were introduced at a very young age, and they produce urine with a strong, musky smell. Some people, however, prefer the personality and curiosity of male mice. It is a good idea to keep fancy mice in pairs if possible, since they are sociable animals. However, if a buck and a doe of breeding age are put in the same cage they will keep reproduce every three weeks until separated.

Baby Mice.

Mice should be kept in well-ventilated areas. Fish tanks or cages with bars and plastic flooring make good housing. The best products for in-cage bedding are aspen wood shavings, dried corn cob, or a commercial paper-based material. Mice can also be given newspaper with black-and-white printing for nesting. Small hide-aways and toys (such as a cardboard tube) are also good to have in the cage.

Food for fancy mice is relatively inexpensive. Veterenarians generally recomend a product called lab block, a scientifically-formulated blend originally desinged for mice in laboratories. Dry dog food is another good option when lab block is unavailable, as it offers balanced nutrition for a mouse and helps keep their teeth conditioned. In order to keep variety in their diets, mice can also eat oats, oily seeds, clean egg shell, breakfast cereal, and stale bread. They should also have clean water at all times and some sort of chewing wood in order to keep their teeth from growing too long.

Cat owners must also take special precautions to ensure that the mouse's housing is secure, as even the friendliest of domestic cats have been known to torment or kill fancy mice if given the chance.

Breeding mice

Bucks and does should be housed in separate enclosures until you want to breed. When the time comes you can place them together. When they have mated remove the male to stop him from remating with the female or harming the young. Several does can have their young together; they will keep all their young in one place. The young mice will suckle the mother, then wean onto solids. Then it is a good idea to move them into two separate cages, one for males and the other for females, at 5 weeks old. Make sure bucks have contact with other male mice, not only their siblings, or they may not be able to live with older males later on.

Mice clubs

Many fancy mice clubs have been set up around the globe. Shows are also held so owners can display their mice. See External links below.
