Hamsters won't die from overeating even if there is too much food provided, because they have unique physiological structures and behavioral habits to avoid excessive consumption. Here are the specific reasons and precautions:

Cheek Pouch Storage Mechanism
Hamsters have cheek pouches in their mouths. Excess food is stored in the cheek pouches instead of directly entering the stomach. Once the cheek pouches are full, hamsters will stop eating. Therefore, they won't die from overeating all at once.
Instinct of Stockpiling Food
Hamsters have the natural instinct to hoard food. They will hide the excess food in their cheek pouches or in the corners of their cages for future use. This behavior helps them survive in the wild. However, in a domestic environment, the stored food may become moldy and spoiled, which can affect their health.
Feeding Suggestions
- Regular and Portioned Feeding: It is recommended to feed hamsters once in the morning and once in the evening. Avoid overfeeding to reduce the behavior of hamsters hiding food.
- Food Selection: Avoid feeding snacks that are high in fat and sugar. Instead, choose special hamster food and an appropriate amount of fruits and vegetables to keep hamsters healthy.
Health Risks
Although hamsters won't die from overeating, the stored food may become moldy and spoiled, leading to the growth of bacteria and increasing the risk of hamsters getting infected with diseases. Therefore, it is very important to clean the cage regularly and check the stored food.
In conclusion, hamsters won't die from being given too much food, but owners still need to pay attention to the feeding methods and food management to ensure their health.
