Hamster Cages
Most pet-shop hamster cages are far too small. Hamsters roam huge distances at night and dig deep burrows, so floor space and bedding depth matter more than colourful tubes — here’s how to choose a home they’ll actually thrive in.

How big should a hamster cage be?
UK welfare guidance points to a minimum of around 100 × 50 cm of unbroken floor space — and bigger is always better. Hamsters need continuous floor to roam, not a footprint padded out with shelves and tubes, which they can’t use as actual running space.
Syrian hamsters are larger and must live alone; dwarf species are smaller but still need that generous floor. Bar spacing matters too — dwarfs squeeze through gaps that hold a Syrian, so check it’s tight enough for your species.
What makes a good cage
A deep base is essential. Hamsters are burrowers and need at least 15–20 cm of bedding to dig proper tunnels, so look for a tank-style or deep-tray cage rather than a shallow one. Pair it with a solid (never wire) wheel that’s big enough for a flat back — at least 20 cm for a Syrian.
Good ventilation, a secure door, and easy-clean access round it off. Avoid cages that rely on a maze of plastic tubes, which trap heat, are hard to clean and offer little real exercise.
Everything here is chosen to be genuinely useful in everyday life with your pet — quality-checked, fairly priced and shipped tracked across the UK. For any health concern, your vet is always the best first port of call.
Common questions
What size cage does a hamster need?
Aim for at least 100 × 50 cm of continuous floor space — current UK welfare advice — and more if you can. Floor area matters far more than height, tubes or shelves.
Do hamsters need a deep base for bedding?
Yes — hamsters are natural burrowers and need 15–20 cm of bedding to dig tunnels. A deep tank-style or high-base cage lets them do this; a shallow tray doesn’t.
Can two hamsters share a cage?
Syrian hamsters are strictly solitary and must live alone. Some dwarf species can be kept in same-sex pairs from young, but they still need a large cage and may fall out, so always have a spare setup ready.
