Hamster housing
The minimum sized housing we adopt Syrian hamsters out to is 100x50cm floor space, for dwarf hamsters minimum 80x50cm. Ideally though dwarfs also need at least 100x50cm floor space. If you're starting out with an 80x50cm please upgrade them at the earliest opportunity!
Examples of suitable housing for hamsters:
(please note - some of these cages come with unsuitable accessories that shouldn't be used)
Savic Plaza: 100x50cm
Bar spacing may be too wide for Roborovskis. The tray isn't deep enough to provide Syrians with enough burrowing depth but could be modified

Savic Mickey 2XL: 80x50cm
Starter cage for dwarf hamsters. Narrow bar spacing so also suitable for robos

All types of hamsters love burrowing so like to have deep bedding. We mostly use Aubiose + Megazorb. Most pet shop woodshavings are unsafe.

Bedding/substrate
All fluffy types of nesting material are unsafe, even if they're marketed as 'safe'. Use teabag type nesting material instead or non-scented loo roll ripped up
