The behavior of hamsters hoarding food is mainly driven by their survival instincts and adaptation to the environment.
First of all, hamsters store food in their mouths to survive in environments where food is scarce. This behavior can be traced back to their ancestors, the steppe hamsters, who also lived in food - scarce environments and coped with food shortages by storing food. The non - social nature of hamsters also prompts them to store food in their nests to avoid competing with other animals for food.
Secondly, the living environment of hamsters is rather monotonous and food is scarce. Therefore, they instinctively hoard food for future needs. This behavior is a survival wisdom ingrained in their genes, much like humans stockpiling dry rations. Hamsters not only store food in their cheek pouches but also carefully carry it into their nests, as if saying, "These are all my treasures, and no one can take them!"
In addition, the cheek pouches of hamsters need to be checked regularly and kept dry. Do not feed them foods that are highly sticky, perishable, or sharp. These kinds of foods may cause inflammation in the cheek pouches and affect their subsequent eating.
