The Roborovski Hamster

___________________________________________________


The Roborovski Hamster originates from Western and Eastern Mongolia and Northern China. Roborovski Hamsters were imported into the UK in the 1960s by London Zoo but the present UK stock was imported from Holland in 1990. Roborovski Hamsters were later imported into the USA and are now available as pets in many countries.
The Roborovski Hamster is the smallest of the hamster species kept as pets, being only around 4-5 cm in length. The natural colour is sandy-gold over the back with a white belly and distinctive white "eyebrows" which gives them a very appealing appearance although other varieties exist.

Roborovski Hamsters are extremely active and fast and so are not widely kept as a pet as they are much more difficult to handle than the other species of Dwarf Hamster. This makes them unsuitable pets for children who want a pet they can hold and play with but are a fascinating pet for those who prefer simply to observe, particularly when given a large and interesting environment in which to live. Roborovski Hamsters are, however, of very good temperament and rarely nip.
As Roborovski Hamsters are not a suitable pet for children they are rarely seen in pet shops but can be obtained from specialist hamster breeders in various countries.

The average lifespan of the Roborovski Hamster is 3-3½ years although they can live longer.

The Dwarf Winter White Russian Hamster

___________________________________________________


The Dwarf Winter White Russian originates from Eastern Kazakhstan and South West Siberia where it lives amongst grassy steppes.

The Dwarf Winter White Russian Hamster is the least common of the two species of Dwarf Russian Hamster kept as pets and is therefore rarely seen in pet shops. The Dwarf Winter White Russian is sometimes also known as the Siberian Hamster. Both the Dwarf Campbells Russian Hamster and the Dwarf Winter White Russian Hamster are sometimes labelled as Djungarian Hamsters. The Russians themselves refer to the Dwarf Winter White as the Djungarian but American Scientists refer the Campbells as the Djungarian. It is however a very misleading name as neither species actually inhabit the area of Djungaria.

The Dwarf Winter White Russian Hamster is more compact in shape than the Dwarf Campbells Russian Hamster and has more prominent eyes, a roman nose and a curved spine towards the rear giving it a bullet shaped body. Dwarf Winter White Russian Hamsters are approximately 8-10cm in length when full grown with males being larger than females. They have expandable cheek pouches. Russian Hamsters have furry feet and are sometimes referred to as the Furry or Hairy Footed Hamster.
The Dwarf Winter White Russian Hamster is so called because of its tendency to turn white in the winter. This is due to the shorter daylight hours and the hamster's coat may become lighter or have white patches or become almost completely white. Dwarf Winter White Russian Hamsters do not normally breed when in their winter white coat.

The Dwarf Winter White Russian Hamster is sociable and will live with others of its own kind in single or mixed sex groups provided that hamsters are introduced at a young age. The Dwarf Winter White Russian Hamster is nocturnal but can be quite active for short periods during the day. It makes a good pet although because of its small size it can be difficult for small children to handle. The Dwarf Winter White Russian Hamster can also be less tolerant of clumsy handling than the bigger Syrian Hamster but is generally nice natured. They are able to squeeze through the bars of some hamster cages and so cages designed for mice, glass or plastic aquariums make more suitable cages. The average lifespan of the Dwarf Winter White Russian Hamster is 1½-2 years although they can live longer.
Due to the similar appearance of the Dwarf Campbells Russian Hamster and the Winter White Russian Hamster and their ability to interbreed it may be difficult to distinguish which species a particular hamster is, or indeed if it is a hybrid of the two species.

The Dwarf Campbells Russian Hamster

___________________________________________________


The Dwarf Campbells Russian Hamster inhabits the Steppes and semi deserts of Central Asia; the Altai mountains Tuvinskaya Autonomous Region (Tuva), Transbaikalia, Mongolia, Nei Mongol (Inner Mongolia), and the adjacent parts of Heilungkiang and Hebei provinces of Northeastern China, where it lives in sand dunes.

The Dwarf Campbells Russian Hamster (sometimes incorrectly labelled as the Siberian Hamster in pet shops) is the more common than the other species of Dwarf Russian Hamster, the Dwarf Winter White Russian (Siberian) Hamster, and is often seen in pet shops in many countries today.

Both the Dwarf Campbells Russian Hamster and the Dwarf Winter White Russian Hamster are sometimes labelled as Djungarian Hamsters. The Russians themselves refer to the Dwarf Winter White as the Djungarian but American Scientists refer to the Campbells as the Djungarian. It is however a very misleading name as neither species actually inhabit the area of Djungaria.
The Dwarf Campbells Russian Hamster is approximately 10-12cm in length when full grown, with males being larger than females. The Dwarf Campbells Russian Hamster has a plump rounded body and expandable cheekpouches. Russian Hamsters have furry feet and are sometimes referred to as the Furry or Hairy Footed Hamster.
The Dwarf Campbells Russian Hamster is sociable and will live with others of its own kind in single or mixed sex groups provided that hamsters are introduced at a young age. The Dwarf Campbells Russian Hamster is nocturnal but can be quite active for short periods during the day. It makes a good pet although because of its small size it can be difficult for small children to handle.

The Dwarf Campbells Russian Hamster can also be less tolerant of clumsy handling than the bigger Syrian Hamster and more prone to nip when annoyed. They are able to squeeze through the bars of some hamster cages and so cages designed for mice, glass or plastic aquariums make more suitable cages. The average lifespan of the Dwarf Campbells Russian Hamster is 1½-2 years although they can live longer.
Due to the similar appearance of the Dwarf Campbells Russian Hamster and the Winter White Russian hamster and their ability to interbreed it may be difficult to distinguish which species a particular hamster is. So how do you tell if you have a Campbells, a Winter White or a hybrid?

Syrian hamsters

_________________________________________________________

The Syrian Hamster is sometimes referred to as the 'Golden Hamster' due to its original wild golden colouring although today there are many different colour and coat mutations. It is also sometimes referred to as the Standard or Fancy Hamster and Long Haired Syrian hamsters are sometimes referred to as 'Teddy Bear Hamsters'. In addition the Hairless Syrian Hamster is sometimes referred to as the 'Alien Hamster' and the Black Syrian Hamster is also referred to as the 'Black Bear' or 'European Black Bear' Hamster.
The Syrian Hamster is the most common type of hamster kept as a pet and is approximately 6-7 inches in length with a very short tail. It has hairless feet with four toes on the front feet and five on the back feet. The Syrian Hamster has expandable cheek pouches which it uses to collect and carry food and bedding and it can carry up to half its body weight in grain in its cheek pouches

The Syrian Hamster is a solitary animal and will not usually live with another past 8-10 weeks of age and so it is important that they are housed separately as serious fighting, even death can occur if more than one are kept in the same cage. The Syrian Hamster is nocturnal, usually waking during the evening.

The Syrian Hamster makes a good pet and easy enough for small children to handle under supervision. The average lifespan is 2-2½ years although they can live longer and up to 3-4 years is not too unusual.


BREEDING HAMSTERS

___________________________________________________

Before breeding hamsters consideration should be given as to whether the pair of hamsters that it is intended to breed are a good match to produce healthy, good natured babies and also make plans for homing the babies produced.

When considering which pair of hamsters to breed together it is important to consider their size, health and temperament as both good and bad qualities present in the parents will be passed onto the babies. It is also important to correctly identify the colours of the pair it is intended to breed together as some colours of hamster produce undesirable babies (eg eyeless hamsters) when bred together.

The average litter size for a Syrian hamster is 8 but they can have up to 26 babies although this is extremely rare. However it is not unusual for litters of 10-14 to be produced and survive.The average litter size for Dwarf hamsters is 4-6 but they can have larger litters and the Dwarf Campbells Russian Hamsters can have up to 14 babies and litters of 8-10 are not uncommon.

It is therefore vital that consideration is given and plans made for homing the babies before making the decision to start breeding hamsters taking into account that 14-26 babies could be produced from a single mating. Many local pet shops have regular suppliers so don't rely on these to take surplus babies without speaking to them before making the decision to start breeding your hamsters.

How to Tame Your Hamster

__________________________________________________

Taming can be a long process, don't expect your hamster to suddenly like be handled over night. It can take weeks or even months depending on the hamster. When you first get your hamster leave it alone for the first 24 hours to let it get used to it's surroundings. After this time feed your hamster some treats from your hand so they get used to seeing your hand. Wait until your hamster wakes up on it's own to do this, hamsters don't like being woken up and it could result in you getting a nasty bite.

Once your hamster seems confident with taking treats out of your hand you can try to start handling your hamster. Before you handle your hamster make sure you have washed your hands well. Hamsters have a strong sense of smell. If they smell something on your hand they may mistake it for food and decide to bite!

Get a cup or something similar and place it into the hamster's cage. He should come to investigate and crawl inside. Take the hamster and cup out of the cage and let him walk out onto your hand. While you do this make sure you're sat down or sat close to the floor incase your hamster decides to jump. Let him walk from hand to hand. Be careful you don't grab or wrap your hands around your hamster until he is fully tame as this may scare him and he'll jump out of your hand.

Once your hamster is more confident with you, you can start to pick up your hamster straight from it's cage. Just make sure your hamster is aware that you are there, if not you may suddenly scare the hamster and it may turn around and bite you.

Breeding & Mating

__________________________________________________

Breeding

There are many things to consider before you decide to breed. It's something that shouldn't be rushed into. What will you do with the hamsters that are born? Many pet stores don't take hamsters from the general public. So will you keep the hamsters for yourself or try to sell them to your friends and family. Syrians can produce as many as 15 pups, will you have the space to cage all these hamsters seperately when they become adults? Another thing to consider is do you have the time and money to do this? If the hamsters become ill and need vet care will you have enough money, vet care isn't always cheap. Or if the mother suddenly dies after birth this will mean you will have to take care of the pups yourself. That will be very hard to do for someone who is at work or school. Don't go into breeding hamsters thinking you can make some money from this because you won't.

Mating

Hamster become sexually mature as early as 4-5 weeks old but this is way too young to start breeding and can lead to complications. The best age to breed a female is from 4 months old. A female syrian will go into heat every four days. This fourth day is the day when you should attempt to mate. When the time is right place the female in the males cage or create a neutral area for them to mate. Never place the male into the females cage.

When placed together they should begin to sniff each other and the male will mount the female. Once they've finished seperate them in their cages. If the female isn't ready she will attack the male, seperate immediately and try again the next night.

In dwarfs it is a little different the male and female can stay together until the birth if you wish as long as they get along well.

Feeding Your Hamster

_________________________________________________

A hamsters diet mainly consists of a dried mix that can be bought in pet stores. This will contain all the vitamins and minerals a hamster needs. Make sure the mix you buy doesn't contain too many seeds or nuts because too many of these can make your hamster fat. One thing to note when feeding dwarf hamsters is not to feed too many sugary foods as this could lead to diabetes. You should provide two teaspoons of the dry mix each day. Any food that your hamster doesn't eat should be thrown away.

Along with the normal hamster mix you can also feed your hamster fresh fruit and vegetables once or twice a week. Be careful you don't feed too many of these as it may cause the hamster to get diarrhoea.

The following is a list of some foods you can feed your hamster

  • Banana
  • Sweetcorn
  • Cucumber
  • Apple
  • Cheese
  • Turnip
  • Raisins
  • Peas
  • Carrot
  • Celery
  • Bread
  • Grapes
  • Melon
  • Chicken

Never feed your hamster these foods :

  • Chocolate
  • Raw Kidney Beans
  • Garlic
  • Onions
  • Raw Potato
  • Sweets

Sexing Hamsters

__________________________________________________

Sexing a hamster can be quite easy to do once you know what to look for. Male hamsters have more rounded bottom. On a male you can see two holes which are the penis and the anus, these are far apart. Females also have very similar holes, which are very close together sometimes even looking as one on a dwarf hamster. On a female these are the vagina and anus.

Housing

_______________________________________________________

Housing
Hamsters can be kept both in cages and in terraria, both of which are available in pet stores. Cages are easier to carry; their bars can be used for climbing. On the other hand, glass boxes keep hamsters from throwing litter out of their cages, provide a better view into the hamster's home, and create a quieter and more sheltered interior.

Despite the hamster’s small size, appropriate housing should always have a floor space of at least two square feet and a strong top because hamsters are surprisingly good climbers. Glass boxes must not be higher than their width to allow for a sufficient air circulation. Although smaller in size, dwarf hamsters often need more spacious housing than their larger relatives, at least 80cm by 40cm (2 feet by 4 feet) due to their high activity levels.

In the case of self-built dwellings, care should be taken to avoid materials that are dangerous to the animals. Plywood and wood from conifers is not suitable, because hamsters gnaw at their houses and both glue and resin are poisonous to them. Using standard water-soluble white wood glue to join pieces of solid wood, such as birch or beech wood, creates a safe environment for the hamster, although it may still chew through the wood. A purchased cage can be equipped with several intermediate levels, connected using stairs.

Hamsters do best in a well-lit room of constant, moderate temperature (18 to 26°C, 64 to 80°F), in a place out of strong sunlight that could cause dangerous overheating. Dwarf hamsters like it a bit cooler.

The floor of a hamster's residence is generally covered with a layer of litter. Litter made from recycled paper or wood lacking aromatic oils (such as aspen) is healthiest - gnawing and eating cat litter can be deadly, and cedar, pine, or other softwood-based litters may contain phenols that can irritate a hamster's respiratory system, liver, and skin. There is also commercial bedding available, such as Carefresh and Megazorb.

Reproduction

_______________________________________________________

Hamsters become fertile at different ages dependent on their species, but this can be from one month to three months of age. Male hamsters remain fertile for the rest of their lives, though females do not. Females are in heat approximately every four days.


Breeding season is from April to October, with two to five litters of 1 to 13 young being born after a gestation period of 16 to 22 days.[1] Gestation lasts 16 to 18 days for Syrian hamsters, 18 to 21 days for the Russian hamsters, 21 to 23 days for Chinese hamsters and 23 to 30 for Roborovski Hamsters. The average litter for Syrians is about 7, but can be as great as 24, which is the maximum number of pups that can be contained in the uterus. Campbell's Dwarf Hamsters tend to have 4 to 8 in a litter but can have up to 14. Winter White Russian Dwarf Hamsters tend to have slightly smaller litters, as do Chinese and Roborovski hamsters.


Hamsters are born hairless and blind in a nest which the mother will have prepared in advance. She uses shredded material such as leaves in the wild but prefers cotton or toilet paper in captivity. After one week they begin to explore outside the nest. They are completely weaned after three weeks, or four for Roborovski Hamsters. Most breeders will sell the hamsters to shops when the hamsters are anywhere from two to eight months old.


Characteristics

_______________________________________________________

Hamsters are stout-bodied, with tails much shorter than body length and have small, furry ears, short, stocky legs, and wide feet. Their thick, long fur can be black, gray, white, brown, buff, yellow, and red depending upon the species; underparts are white to shades of gray and black. The Dzhungarian hamster (Phodopus sungorus) and the striped dwarf hamster (Cricetulus barabensis) have a dark stripe down the middle of the back. Dwarf desert hamsters (genus Phodopus) are smallest, with bodies 5 to 10 cm (about 2 to 4 inches) long; the largest is the common hamster (Cricetus cricetus), measuring up to 34 cm long, not including a short tail of up to 6 cm. As hamsters have live birth (i.e. do not lay eggs) and give milk, they are considered mammals.

History of the Hamster

________________________________________________________

It all began in 1930 with one mother and twelve young hamsters that a zoologist found in the Syrian Desert (situated in the Middle East to the north of Israel). Deep in a burrow eight feet underground he came upon a hamster mother and her litter. By the time he got his tiny family back to his laboratory in Jerusalem. All but three of them had died or escaped. These three, however, continued in excellent health and within four months the first litter of Golden Hamsters ever to be born in captivity was delivered.


As they matured, these babies were interbred, and as the tame hamsters multiplied they were used in research experiments. Soon they began to attract widespread attention in the scientific world. Because hamsters were so disease-free and bred so rapidly (they can have a new litter every month!) and because they were so friendly and easy to handle, they came to be highly regarded as laboratory animals and their fame spread throughout the world accordingly. They're often used for cardio-vascular research, as their cardio-vascular system is remarkably similar to that of the human.

From Jerusalem, scientists took them to laboratories in France, England and, in 1938, to the United States. All present-day Golden Hamsters in captivity with the exception of a few brought back by travelers and military men are the descendants of that first tiny family found in Syria.

In Syria and other Middle Eastern countries where hamsters are common, the farmers do not only harvest their own fields, they dig into the hamsters' granaries as well. In each burrow they find a storage bin which may hold anywhere between 30 and 60 pounds of grain which the hamsters have stored away for the winter.

Hamsters got their name from an old German word associated with storing food. (The word "hamper" comes from the same root.) One of the characteristics of the hamster, like many rodents, is to stuff their cheeks full of food, which is a hamster-like activity.
