Identify your hamster’s species before buying its home. Syrian, Chinese, Campbell’s, winter white and Roborovski hamsters differ in size and needs; a product labelled “hamster cage” is not automatically suitable.
Space to burrow and explore
Blue Cross recommends housing no smaller than 100 × 50 cm of floor space and 50 cm high, with at least 20 cm of suitable burrowing bedding. Larger accommodation gives more room for natural behaviour. Keep it securely covered and well ventilated, with space for deep bedding rather than narrow connecting tubes.
Provide a multi-chamber hide, tunnels, nesting material and a suitable sand bath. Use an upright wheel with a solid running surface, large enough for a straight back. PDSA recommends at least 30 cm for Syrians; smaller species still need an appropriately sized wheel, not the smallest one sold.
Plan for one hamster
This beginner setup follows PDSA’s advice to house pet hamsters separately. Syrian and Chinese hamsters are particularly unsuitable for sharing. Dwarf hamsters should not be assumed to need a partner: group housing can lead to stress and fighting.
Food and water
Choose a balanced food formulated for hamsters, with small suitable fresh-food additions. Scatter part of the normal ration to encourage foraging. Remove spoiled fresh food and check the amount eaten. Provide clean drinking water and check its supply daily.
Respect their routine
Let your hamster sleep during the day and approach it gently when awake. Support it close to a safe surface rather than squeezing or scruffing it. Monitor appetite, droppings, breathing and activity. Diarrhoea, a soiled rear, reduced eating or breathing difficulty needs prompt veterinary help; “wet tail” is not a single diagnosis that can be treated from a website.
