Hamster cage size, bedding depth and wheel size: setting up a good enclosure
TUREFF• •0
Most hamsters spend their whole lives in one enclosure, so it shapes their welfare more than anything else you buy. Many cages marketed for hamsters are far too small. Here is what to look for instead.
How big should a hamster cage be?
Bigger is better, and floor space matters more than height or levels. Advice varies between organisations and has changed over the years, so there is no single official number. Some welfare charities now avoid giving a minimum at all and simply say to provide as much space as you possibly can; hamster welfare groups and many vets recommend continuous floor areas measured in metres rather than centimetres. In practice:
- choose the largest enclosure you can fit
- look at unbroken floor space, not total area across shelves and tubes
- treat cages from small starter kits as too small for an adult hamster
A hamster in too small a space may chew the bars constantly, climb and drop from the roof, or pace back and forth. These are signs of stress, not play.
Types of enclosure
- Large wire cages with a deep plastic base allow good airflow. Check bar spacing is narrow enough for your species; dwarfs can squeeze through gaps that hold a Syrian.
- Bin cages and converted furniture offer a lot of floor area cheaply; they need a mesh lid and good ventilation.
- Glass tanks hold deep bedding well and give good views, but need a mesh lid.
Avoid cages with a tiny base and lots of narrow tubes, which are hard to clean and can trap a larger hamster.
Deep bedding for burrowing
Wild hamsters dig burrows, and pet hamsters want to dig too. Provide bedding deep enough for the hamster to tunnel in, ideally deeper in at least one part of the enclosure. Good bedding is:
- paper-based or similar soft, dust-free material
- unscented
Avoid cedar and pine shavings that have not been treated to reduce their aromatic oils, and avoid fluffy cotton-style nesting material, which can wrap around limbs or block the gut or cheek pouches. Plain, unscented toilet paper torn into strips makes safe nesting material.
Choosing a wheel
A wheel lets a hamster run the long distances it would cover in the wild. Look for:
- a solid running surface, never rungs or mesh, which can trap and injure feet
- a large enough diameter that the hamster runs with a flat back. If its spine curves upwards while running, the wheel is too small. Syrians need a much larger wheel than dwarfs.
- a stable fixing so it does not wobble or tip over
Furnishing the space
- Several hides to sleep in, with more than one entrance.
- A sand bath of plain, dust-free sand. Many hamsters, especially dwarfs, use sand to clean their coats; avoid dusty chinchilla dust.
- Chew items such as untreated wood and cardboard to help wear the teeth.
- Scatter feed rather than using only a bowl, so the hamster forages.
- Different textures and levels at a safe low height. Falls from height can injure a hamster.
Avoid hamster balls. The hamster cannot escape the heat, cannot see well, and cannot stop when it wants to.
Where to put it and how to clean it
Place the enclosure in a quiet room with a steady temperature, away from radiators, direct sunlight, draughts and loud noise. Keep it out of reach of cats and dogs.
Spot clean the toilet corner and remove fresh food leftovers regularly. Avoid changing all of the bedding at once, which destroys the hamster's burrows and familiar scent. Partial changes are less stressful.
