Hamsters can survive for 3 to 5 days without eating. Under normal circumstances, hamsters can go without food for 3 to 5 days without posing a threat to their lives. However, not eating for an extended period of time will cause harm to their health.
The Hunger Resistance Ability of Hamsters
When hamsters eat normally, they will hide food in their cheek pouches. When they feel hungry, they will look for food on their own. In addition, hamsters have a sense of fullness and generally won't overeat to the point of death. But the food placed in the cage is likely to go bad, and if hamsters accidentally eat the spoiled food, it is easy to cause diseases.
Factors Affecting the Hunger Resistance Ability of Hamsters
Environmental Changes: A new environment may make hamsters feel uneasy. In the first week after they arrive at their new home, just make sure they have enough food and water, and occasionally observe their physical condition. After a week, you can slowly lure them with food to let them gradually get familiar with your smell.
Food Issues: Spoiled food may make hamsters reluctant to eat. Check whether the food is fresh. If there is nothing wrong with the food, you can put it in the cage, and the hamsters will naturally eat it when they feel hungry.
The Estrus Period: Hamsters in the estrus period may have a poor appetite, but they will still be energetic. Their appetite will return after the estrus period is over.
Illness: If a hamster is sick, it will also lead to a loss of appetite. Observe whether the hamster has symptoms of diarrhea. If so, it is necessary to use medicine for treatment in a timely manner.
