Roborovski dwarf hamsters are generally tame and rarely nip. However they are particularly nervous and, combined with their very small size and extremely lively nature, this makes them unsuitable for young children who will want to play with them, as they could easily escape when handled. It is recommended that they are only handled in an area where they will be easy to catch if they escape, such as over a large box.
Despite their small size, they are extremely active. They should therefore be housed in as large a habitat as possible to give them the space they need to prevent boredom. A solid sided cage or an aquarium would be the most suitable choice of housing as they are small enough to squeeze through the bars of most wire hamster cages.
They are generally social and so ideally they should be kept in same-sex pairs or small groups, but it is best to introduce them at a young age.
