A dwarf hamster's cage works less like a box and more like a burrow you can see into, so the way you clean it matters as much as how often you do it. This guide describes dwarf hamsters and their care through that one job: bedding, nesting material and the clean-out routine. It draws on the RSPCA's hamster advice and a handful of laboratory studies.
What the hamster is trying to build
The RSPCA describes hamsters as terrestrial, burrow-digging rodents whose natural habitat is dry, rocky plains or lightly vegetated slopes, where they build nests inside their burrows. Wild hamsters live in deep burrows. The charity also warns that they dig quickly and can escape easily from poorly built cages.
The floor of the cage should serve that digging habit. The RSPCA asks for a solid floor, so there is room for bedding that soaks up the fairly small amount of urine hamsters produce, and it advises against wire mesh floors. The bedding should be deep enough to dig in. If you can, add an area of litter deep enough for a proper burrow.
Choosing bedding and nest material
The RSPCA weighs up the litter options in a few lines. Coarse sand is natural but awkward to handle, and peat works but discolours the coat. Dust-free wood shavings or granulated corn cob, with no preservatives or other chemicals, are its "good compromise". For the nest itself it lists good-quality hay, wood wool, shredded paper or cardboard. It rules out cotton wool and similar "fluffy" products that separate into thin strands, because a hamster can become tangled in them.
Laboratory work points the same way. In a 1994 study at Hendrix College, most of 40 golden hamsters chose a solid-floored plastic cage with corn-cob litter over a wire-floored steel one, although 40% of the animals that had lived on wire for a long time came to prefer it. A 2006 study at the Université de Moncton gave Syrian hamsters connected cages with different beddings. In paired tests they picked shavings over wood pellets. Once a piece of paper towel was added as nest material and four beddings were offered at once, the preference disappeared. The authors concluded that none of the four materials was inappropriate in the short term, provided nesting material is added and the litter is changed regularly. Both studies used golden (Syrian) hamsters, not dwarfs, so read them as a general pattern.
A dwarf-specific result comes from the University of California, Berkeley in 2003. Siberian hamsters kept at 5°C ate 18% less food when they had nesting material. That was a cold-room experiment, but it shows how much work a nest does for its owner.
Spot clean often, deep clean rarely
How often a cage needs cleaning depends on its size and on whether the hamsters keep to one toilet area. The RSPCA's view is that a deep clean once or twice a month is enough in most cases. It also advises spot cleaning every few days to take out soiled bedding, uneaten food and droppings, and it says never to let the bedding become damp or smelly.
Timing counts. Clean while your hamsters are awake rather than in the middle of the day, when they are asleep and the disturbance can be stressful. A nesting box with no floor helps here, because you can check on the occupants just by lifting it. The RSPCA suggests putting the box near food and nesting material but away from the water bottle, so a leak cannot flood it. Check the bottle every day for leaks or blockages.
Hamsters like to eat hidden away, and the RSPCA notes that they may carry food in their cheek pouches back to the nest to eat or stash. So the spot clean is also when you find the larder. Wet food is the item to watch. It is hard to clean out and prone to mould, and the charity says to offer it only on a vet's advice and to remove every trace at least twice a day.
Leave some of the old smell behind
Smell is central to a hamster's world. When you clean out the cage, the RSPCA recommends moving a small amount of old, unsoiled bedding and nesting material into the fresh setup, especially for hamsters kept in groups. Objects soiled by droppings should be cleaned or replaced, since those odours may set off fighting.
Research on dwarfs shows how much scent carries. A 1987 study found that male Campbell's dwarf hamsters scent marked more often where another hamster's odour was present than in clean areas. In 2016, Indiana University researchers sampled the ventral gland secretions of Siberian hamsters and found that males produced a more varied chemical mix than females. A fully scrubbed cage wipes out all of that in one go. The RSPCA's own reason for carrying old bedding over is simply that smell is very important to hamsters.

Where fruit, and dates, fit in
The RSPCA's food list starts with a compound pellet ration or a mixture of seeds. It then adds small quantities of greens, cleaned root vegetables and pieces of fruit such as apples, and it warns never to give grapes or rhubarb, which can be poisonous to rodents. It also says to avoid sudden changes to the diet and stale food. Dates are not on the list. If the kurma in your kitchen came from a wholesaler such as Pemborong Kurma Green Diamond, a date supplier in Shah Alam, Selangor, the RSPCA advice says nothing about them, so ask a vet before offering any.
Those dates are for the people in the house. Pengedar Kurma Malaysia supplies everything from retail purchases to wholesale supply and delivers across the country, as its about page explains. Questions, price quotes and orders go through WhatsApp from the contact page, and other articles are collected on the Pengedar Kurma blog.
