Where to see them

Did you know…

  • Unlike its domestic relative the Syrian hamster, this wild European species grows considerably larger and is listed as critically endangered across much of its original range.

    From Common Hamster

  • In the wild its coat turns white in winter, which is rare among rodents.

    From Striped Desert Hamster

  • It turns white in winter: it is one of very few rodents with a seasonal colour moult, and in captivity that change does not happen because artificial lighting stops it perceiving the shortening days.

    From Striped Desert Hamster

  • In the wild the males take an active part in the birth and care of the young, which is exceptional among rodents: they help to clean them and keep them warm while the female feeds.

    From Striped Desert Hamster

  • The smallest hamster kept as a pet: some 8 cm and 25 grams.

    From Desert Hamster

  • It is the smallest hamster in the world: an adult sits comfortably in the palm of a hand.

    From Desert Hamster

  • In a single night it can cover several kilometres on an exercise wheel, a distance consistent with how far it walks in the desert looking for seeds.

    From Desert Hamster

  • Almost every domestic golden hamster in the world descends from a single female with twelve young caught at Aleppo in 1930 by the zoologist Israel Aharoni.
