To calm a hamster down quickly, you’ll need to combine environmental adjustments, interaction techniques, and daily habit building. Here are specific methods:

1. Handling Emergencies (When a Hamster is Frightened or Stressed)
Stop Disturbances Immediately
Move the cage to a quiet, dimly lit area, avoiding noise or sudden movements.
Do not forcefully pick up or pet the hamster—it needs time to recover on its own.
Provide a Safe, Hidden Space
Add hiding spots like cardboard boxes or wooden huts to the cage to help the hamster relieve stress.
Use unscented bedding (such as raw wood shavings) to reduce odor irritation.
2. Long-Term Mood Management
Build a Trusting Relationship
Scent Familiarization: Place your clothing or hand-warmed bedding in the cage to help the hamster gradually get used to your scent.
Hand-Feeding Treats: Feed the hamster by hand at a fixed time daily (e.g., with sunflower seeds or oatmeal) so it associates you with food.
Environmental Optimization
Keep the cage temperature stable (20–26°C) to avoid large temperature fluctuations.
Provide toys like exercise wheels and tunnels to meet their nocturnal activity needs.
Interaction Tips
Pet the Right Spots: Hamsters enjoy being petted on the chin and back; avoid touching their belly or tail.
Playtime: Let the hamster explore freely in a safe area (such as a playpen) for 15–30 minutes daily.
3. Notes
❌ Avoid suddenly reaching from above, as hamsters perceive this as a threat.
❌ Do not frequently rearrange the cage setup—hamsters rely on a familiar environment.
✅ If a hamster remains puffed up or refuses food for more than 24 hours, consult a veterinarian.
With these methods, hamsters will usually gradually relax and adapt to interactions within 1–2 weeks.
