Checklist Hamster The hamster

The Hamster (Mesocricetus auratus, Family Cricetidae, Order Rodentia) is a small friendly gnawer who is very popular in the Netherlands. Hamsters are often kept as pets. There are different types of hamsters. We distinguish the following types of ham that are also kept as pets:

  • Syrian Hamsters (Goudhamster)
  • Russian Dwarf Hamster
  • Campbelli Dwarf Hamster
  • Chinese Dwarf Hamster
  • Roborovski Dwarf Hamster

Head-body length : up to 18 cm
Body weight : up to 180 g (females are slightly heavier than males)
Life expectancy : 2 to 3 years

Details anatomy of the hamster

  • Tooth formula: 1013/1013 (Ratio of cutting teeth at top - bottom = 1: 2-3)
  • Cut teeth continue to grow.
  • Choosing not to continue to grow: The large cheek pouches that run through to the shoulder blades are a flexible protrusion of the cheek mucosa.
  • Gastric consists of two chambers: the anterior and glandular stomach.
  • Small appendix with limited ability to process raw fibers. Protein-rich bowel cocks are only eaten when the food shortage occurs.


Continuous wear ensured by peeling seeds and gnawing on structured fibers (eg hay from nature-protected meadows with mealworms, straw, branches). Young animals and food can be transported to their burrows in the cheek pouches. The amount of raw fibers in their portions may not exceed 10%. Sudden changes in the feed must be avoided.

Spreading the hamster

  • originally from Syria and the south of Turkey
  • threatened


Natural habitat of the hamster

  • Formerly in dry steppe areas, which today have been largely converted into watered agricultural land.
  • Preferably on sandy clay soils with self-built caves.


Behavior of the hamster

  • in fields active during the day
  • under the care of people, active at night
  • solitary with territorial behavior
  • social contacts only in the mating season and in the raising of young animals
  • storage rooms are laid out


Reproduction of the hamster

  • Sexually mature: females after 4-6 weeks of males after 6-7 weeks
  • Breeding : female s after 8 - 10 weeks of males after 10-12 weeks
  • Roll number : 3-4 per year
  • Worm size : 7 (max 12) little ones per litter
  • Wearing time : 15-18 days
  • Birth weight : 2-3 g, litters
  • Weaning time : from week 4


Details of the reproduction of the hamster

  • In the short period before and during the fertile period, females are tolerant towards the males.
  • If the female has not had a successful mating during the approximately 12-hour fertile period, she will return to a fertile period after 4 days.


Gender differences : the distance between the sexual opening and the anus is greater for the male than for the female.

Feeding the hamster

Granivore, part insectivore / carnivore: seeds, grains, vegetables, herbs, grasses and animal proteins. Give good quality hay every day, eg hay from nature-protected meadows with mealworms as well as fresh drinking water. Fresh food such as vegetables and herbs may be offered in limited quantities after slow habituation.

Balanced long-life recipe: HamsterDream BASIC / EXPERT - supplemented during the growth phase with Juniors Extra granivore - cover the nutritional needs of hamsters.
Feeding a balanced, complete feed in unlimited quantities is important because of the high metabolism. HamsterDream BASIC / EXPERT contain mealworms as a source of animal protein.

The right composition of the hamster transport

  • Crude protein (Rp): 14-18%
  • Crude fat (RVe): 5 to max. 7%
  • Raw fibers (RVz): max. 10%
  • Calcium (Ca): 0.5-0.8% - Adult animals: 0.6% Ca to avoid bladder dust / stones
  • Phosphorus (F): 0.3-0.4% (Ca-F ratio: 1-1.5: 1)


Multicomponent feed with a multitude of components corresponds to the natural feed intake behavior of hamsters and is geared to the animal.

Housing of the hamster

  • just keep it
  • males and females only tolerate each other during the fertile period
  • not possible to keep in a group


Position of the hamster cage

  • draft-free
  • no direct sunlight
  • quiet location without disturbances during the day
  • relative humidity <70%
  • ambient temperature 20 to 24 ° C


If the ambient temperature is below 15 ° C for a long time, the animals can fall into hibernation. To avoid association with predators, the cage / aviary must be on an elevation and the opening must be on the side.

Hamster size

  • at least 100 x 50 x 50 cm


A large, structured cage allows for intensive movement during the active phase.

Ground cover for hamsters

  • well absorbent
  • scented, very ammonia binding
  • dust-free
  • soft
  • replace regularly


Decoration of the hamster cage

  • 1 sleeping house of 15 x 15 x 10 cm and a storehouse
  • hay or cellulose as nesting material
  • tubes of clay, cork, wood or cardboard
  • twigs of deciduous and fruit trees
  • gnawing eg. Back to the ROOTS Gnawing root pleasure
  • bath sand for coat care
  • a one-sided closed running wheel with closed running surface and a diameter of at least 30 cm
  • feed in firm trays of clay or ceramics
    (clean the dishes daily)
  • drinking water in bottles or dishes (change the water daily)
  • food bowl, water bowl and bowl with sand to bathe in a raised place (eg on a house or a bridge) to ensure that they are not knocked over when digging


Indigestible hamster warts can lead to blockage of the cheek pouches and cut-off of limbs. A sand bath is important for the coat care. The diameter of the walking wheel must be at least 30 cm to avoid damage to the spinal column.

Handling hamsters

  • During the first days, hamsters need a lot of rest when they get used to it.
  • Hamsters are active at night and do not like to be caressed. When they are awakened during the day, they react aggressively and bite them. That's why children can only look at them.
  • Raise the animals with the thumb and forefinger around their chest under their front legs or with both hands make a circle around the animal and lift it up.
  • bunnyINTERACTIVE encourages golden hamsters both mentally and physically, intensifies the bond between owner and animal and improves confidence.


Indications of disease in the hamster

Weight loss, less intake of food and water, altered key and urinating behavior as well as a rough coat include indications of a disease. To determine the cause and the treatment, a veterinarian must be consulted as soon as possible.
Young golden hamsters can transfer LCM agents to humans. Careful in pregnant women!
