How to Set Up a Hamster Cage: NZ Beginner's Guide
5 June 2026
Most hamster cages sold are too small. The right cage size, a proper wheel, deep bedding for burrowing, and what to avoid. NZ beginner's setup guide.
The quick answer: the biggest hamster welfare problem is that most cages sold are far too small. Hamsters need much more floor space than people expect, deep bedding to burrow, and a large solid-surface wheel. Get a big enough enclosure with the right kit and a hamster thrives; cram it into a tiny barred cage and it suffers. Hamsters are also solitary — most species must live alone.
Cage size — go big
- Choose the largest continuous floor space you can — far bigger than typical pet-shop cages. A large glass tank/enclosure or a big bin-style cage often beats small barred cages.
- Floor space matters more than levels — hamsters run and forage on the ground.
- Bar spacing must be small enough that a hamster (especially a dwarf) can't squeeze through or get stuck.
What goes inside
- Deep bedding (at least ~20–30 cm) for burrowing — this is essential natural behaviour, not optional. Use paper-based or other safe bedding. Avoid pine and cedar shavings (harmful) and fluffy "cotton wool" nesting (can wrap around limbs or be swallowed).
- A large, solid (not barred or wire) wheel — too-small wheels force a painful arched back. The wheel should let the hamster run with a flat back.
- A hide/house, chew items (their teeth grow continuously), and a sand bath for cleaning.
- Food bowl and a water bottle or bowl.
- Tunnels and clutter for enrichment and foraging (scatter some food to forage).
Placement and care
- A quiet spot, out of direct sun and draughts, at a stable room temperature. Hamsters are crepuscular/nocturnal — don't site them where night activity disturbs sleep, and don't wake them constantly by day.
- Spot-clean daily; do a fuller clean periodically but don't strip the whole cage at once — keep some used bedding so it still smells like home (a total clean stresses them and triggers re-scenting).
Solitary by nature
Syrian hamsters must live alone — they fight, sometimes fatally. Some dwarf species can *sometimes* be kept in pairs, but it's risky and often ends in separation. When in doubt, house one hamster per cage.
Quick takeaways
- Most sold cages are too small — get the largest floor space you can.
- Deep bedding (~20–30 cm) for burrowing is essential.
- Use a large solid-surface wheel; avoid pine/cedar and fluffy nesting.
- Provide a hide, chews, sand bath, food and water.
- Syrians must live alone; house one per cage unless you really know the species.
