Golden hamster (Syrian hamster) (Mesocricetus auratus)

Short answers

Golden hamster (Syrian hamster): How big does the enclosure need to be?

From 100×80×70 cm (bmt hamster leaflet 2025, the bigger the better; the Swiss animal protection society STS and a study by Fischer et al. 2007 recommend 1 m² of continuous floor space). TVT leaflet no. 156 is cited with at least 100×50×50 cm and a wheel of at least 30 cm diameter with a solid running surface. Legal minimums are far smaller (Switzerland 1,800 cm², Austria 60×30×40 cm) and are only an absolute lower limit.

Golden hamster (Syrian hamster): What temperature does it need?

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

Golden hamster (Syrian hamster): Does it need UVB lighting?

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.

Golden hamster (Syrian hamster): How long do they live?

Life expectancy: 2–3 years, rarely up to 4 years.

Golden hamster (Syrian hamster): Is it suitable for beginners?

Yes – it is considered suitable for beginners (difficulty: Beginner (but not for children under about 12 – nocturnal)).

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 100×80×70 cm (bmt hamster leaflet 2025, the bigger the better; the Swiss animal protection society STS and a study by Fischer et al. 2007 recommend 1 m² of continuous floor space). TVT leaflet no. 156 is cited with at least 100×50×50 cm and a wheel of at least 30 cm diameter with a solid running surface. Legal minimums are far smaller (Switzerland 1,800 cm², Austria 60×30×40 cm) and are only an absolute lower limit.

Substrate

At least 20 cm, better 40 cm deep bedding (bmt) of small-animal litter mixed with hay and straw, pressed down in places so tunnels hold; Swiss law requires at least 15 cm. With 40–80 cm hamsters dig natural burrows and hardly gnaw the bars any more (Hauzenberger et al. 2006). Add a sand bath with low-dust sand.

Feeding

Food

Hamster seed mix of grains, seeds, dried vegetables and herbs as the base, hay at all times, a little fresh food daily (herbs, lettuce, vegetables such as cucumber or carrot), gnawing branches. About once a week a small amount of animal protein (e.g. dried insects, mealworms, low-fat quark). Scatter food so the hamster has to search for it.

Feeding interval

Feed daily in the evening (dry and fresh food); remove fresh leftovers in the morning. Hamsters hoard food – only check the hoard for perishables.

Key facts

Adult size

Head-body length about 13–18 cm, tail about 1.5 cm; weight 80–160 g, females usually slightly heavier.

Life expectancy

2–3 years, rarely up to 4 years.

Origin

North-western Syria and adjacent southern Turkey (Aleppo plateau); all pet hamsters descend from a litter caught in Syria in 1930.

Protection status

No wildlife-protection papers needed, not on the EU invasive species list. The wild form is listed as Vulnerable by the IUCN; pets are exclusively captive-bred.

Brumation

None – do not allow winter rest indoors. Below about 8–10 °C a torpor can set in, which is dangerous for pets; warm the animal up slowly and consult a vet.

Cohabitation

Solitary. Golden hamsters are strict loners and often seriously injure other hamsters, including siblings; Swiss law even requires solitary housing.

Notes

Hamster balls, multi-level cages with little floor space and wheels under 30 cm are unsuitable. Coat varieties such as teddy or rex hamsters are partly criticised as harmful breeding. Do not wake the animal during the day.
