Signs of A Stressed Hamster

Hamsters are sensitive animals. And so, changes to their environment or routine can cause them stress. Some common factors are improper housing, lack of exercise, insufficient diet, loneliness, illness, and excessive noise or light.

A stressed hamster becomes weak day by day and eventually falls to their grave. Here are some signs or behaviors they exhibit when they are stressed:

Signs of A Stressed Hamster

Aggressive Conduct

Stressed hamsters are more likely to act aggressively. Therefore, it is essential to offer them space. Avoid touching them with your fingertips. They have a tendency to bite when agitated.

Hair Loss/Fur Changes

Hamsters that are under stress may overgroom or yank out their fur. If you observe bald spots or thinning hair, your pet is undoubtedly agitated. In addition, tension may lead their fur to grow sparser, oilier, or messy.


Digging excessively or not at all, rolling, rubbing, licking, or running in circles constitute all indicators of an agitated hamster.

Hamster Behavior

Cage Biting

Hamsters can occasionally bite their enclosure. If your companion does this once per week, there is no cause for alarm. However, doing so daily is an indication of difficulty.

High-Energy Conduct

Hamsters under stress may exhibit hyperactivity and restlessness. When they are anxious, they frequently repeat the same circuit around their cage. On occasion, they spend extended periods of time on their exercise apparatus.


Typically, hamsters are very silent. However, they may produce greater disturbances than usual when stressed. When they do so, they attempt to convey that they are anxious, frightened, or distressed.
