Choosing the Right Cage Size
When it comes to hamster cages, the rule is: go big, never small. If you’re thinking about keeping two hamsters in one cage (which is not recommended), the cage should be at least three times larger to reduce the risk of fights. Besides size, you should also consider ventilation, safety, and ease of cleaning.
Recommended Minimum Cage Size
- Dwarf hamsters (e.g. Campbell’s, Winter White): at least 697 in² (e.g. 24 × 30 in)
- Syrian hamsters: at least 930 in² (e.g. 24 × 39 in)
Common Misconceptions
- ❌ “Small hamsters need small cages” → Dwarf hamsters are more active than Syrians and actually need more space
- ❌ “Multi-level cages are better” → Horizontal space is more important than vertical; multi-level cages increase the risk of falls
Once cage size is decided, here are must-have furniture and accessories to meet both basic needs and mental stimulation.

Hamster Wheel (Running Wheel)
Hamsters naturally run on wheels—even lazy breeds like pudding hamsters do it sometimes. For Syrians, the wheel should be at least 10 inches in diameter to avoid back strain. Too small a wheel causes spinal curvature. Also check for quiet operation, safe design, and easy cleaning. Use upright wheels, not flying saucers.

Bedding Material
Bedding simulates a natural burrowing environment and helps absorb waste, odor, and cushion falls (hamsters can fall while running). Recommended options include low-dust aspen shavings or ink-free paper bedding. Change weekly.
Avoid cedar, pine, compressed shavings, and cotton or fabric bedding due to dust and entanglement risks. Also avoid scented bedding.

Food Bowl & Water Bottle
Ensure your hamster has constant access to fresh food and water. Most water bottles are mounted or free-standing. Replace water every 2–3 days and check for proper flow—stuck ball bearings may block water.
Hamster Hideouts
Provide a cozy space for your hamster to rest or stash food and bedding. Options include ceramic houses, layered acrylic huts with cooling water, glass huts, wooden or fabric huts. Choose based on seasonal needs, and make sure:
- No tight gaps that could trap feet
- No sharp wood splinters
- No harmful materials if chewed Prepare multiple hideouts to test.
Other Hamster Supplies
- Chew sticks
- Sand bath containers
- Tunnels and toys for enrichment
- Cooling plates or heat lamps
- Toilet paper rolls — universally loved by all hamsters
Additional Considerations
- Placement & Ventilation: Place the cage in a shaded, well-ventilated area, away from direct sunlight or drafts. Good airflow prevents overheating and high humidity, which are harmful to Syrian hamsters.
- Cleaning & Hygiene: Clean the cage regularly. Remove dirty bedding and leftover food. Deep-clean and disinfect the cage once per week.
⚠️ Common Cage Setup Mistakes
- Overcrowding with furniture: Limits running space — always leave a large open area
- Too many platforms or ramps: Syrians aren’t good jumpers and may fall and get injured
- Using the sand bath as a toilet: Separate bathing and toilet areas to avoid refusal to use either
- Water bottle placed too high: If a hamster has to strain its neck to drink, it can cause discomfort or injury
