Hamsters' biting behavior is often closely linked to their instinctive responses, environmental adaptability, and interaction patterns. Here are the specific reasons and suggested solutions:
I. Main Reasons for Biting
Defensive Biting
Hamsters are naturally timid. In unfamiliar environments or when startled—such as by sudden handling, loud noises, or other disturbances—they may bite to defend themselves.
Reaching directly into their cage or grabbing them from above can easily make them perceive you as a predator, triggering an attack.
Territorial Awareness
Hamsters are sensitive about their territory. Forcing your way into their living space (like their cage) may trigger aggressive behavior.
Physiological Needs
They may nibble fingers lightly when hungry, especially if your hands carry food scents.
A lack of trace elements or being in pregnancy can make them more irritable.
Exploratory Behavior
Hamsters explore objects by nibbling. If this behavior isn’t corrected promptly, it may develop into a habit of biting.
II. Prevention and Improvement Methods
Building Trust
Let new hamsters settle in quietly for 3–7 days upon arrival, avoiding forced interaction.
Use treats (such as crackers) to gently them, helping them gradually get used to your scent.
Proper Interaction
Tap the cage lightly to alert them before contact, then stroke them slowly from the back.
Avoid lifting them by the scruff of the neck; instead, use both hands to cradle them under the armpits.
Environmental Optimization
Provide a quiet, spacious living area to reduce stressors.
Regularly supplement nutrients like electrolyte multiminerals.
Notes
If bitten without breaking the skin, rinse the area with water. If bleeding occurs, clean it with soap and apply a bandage.
It’s normal for hamsters’ teeth to be orange; white teeth may indicate health issues.
With patient guidance and environmental adjustments, biting behavior can be effectively reduced.
