Climate

Daytime temperature

18–24 °C room temperature (bmt hamster leaflet 2025); in the cold activity drops to near immobility, above 26 °C heat stress is likely.

Humidity

40–60 % (normal indoor air, no extra humidification).

UVB

Not needed – nocturnal mammal; normal daylight in the room with a regular day-night rhythm is enough; do not place the enclosure in direct sun.

Enclosure

Minimum size

from 120×50×50 cm (recommended size per the Kaninchenwiese small mammal overview 2025; bmt hamster leaflet 2025: the enclosure must not be smaller than 100×50×50 cm, TVT leaflet no. 162 dwarf hamsters 2025). Bigger is better; the Austrian legal minimum is only 60×30×40 cm. Wheel at least 25 cm (Roborovski at least 20 cm) with a solid running surface.

Substrate

At least 20 cm, ideally 30–40 cm deep bedding of small-animal litter with hay and straw for digging, plus a sand bath with low-dust chinchilla sand (essential for coat care). Do not place heavy objects on the deep bedding – risk of collapse.

Feeding

Food

Dwarf hamster mix of fine seeds, grass seeds and dried herbs (sugar-free and low in grain), hay, a little fresh food daily such as herbs, lettuce or cucumber, gnawing branches. Several times a week a small amount of animal protein (dried insects, mealworms, low-fat quark). No fruit and no sweet treats.

Feeding interval

Feed daily in the early evening and scatter the food; remove fresh leftovers the next morning.

Key facts

Adult size

Head-body length 8–10 cm, tail 0.4–1.4 cm; weight about 30–50 g.

Life expectancy

2–3 years.

Origin

Steppes and semi-deserts of Mongolia, north-eastern China and southern Siberia (Altai, Tuva, Dauria).

Protection status

No wildlife-protection papers needed, not on the EU invasive species list; not threatened according to the IUCN.

Brumation

None – keep at a steady room temperature indoors. Short torpor in cold and short days is possible but undesirable for pets.

Cohabitation

Solitary. According to the bmt leaflet, dwarf hamsters should only be kept alone; pairs and groups often get along for a long time and then suddenly escalate with serious injuries. Austria allows pairs, but solitary housing is the less stressful option.

Notes

Often crossed with the Djungarian hamster; hybrids and Campbell's are considered especially prone to diabetes – feed low in sugar. Digs relatively little and often builds only a nest chamber. Recent taxonomy places the species in the genus Cricetiscus.
