The main reasons why hamsters are prone to death include the following aspects:
Natural Aging and Dying: As hamsters age, their physiological functions gradually decline, and their cells and organs gradually fail, ultimately leading to death.

Diseases and Injuries: Hamsters may die from internal diseases such as heart diseases and liver and kidney diseases. In addition, situations like fights between hamsters and catching a chill can also cause their death.
Stress Responses: Hamsters are extremely sensitive to environmental changes. Excessive fright, extremely high or low temperatures, and other stress responses may lead to the death of hamsters.
Unsuitable Environment: Hamsters have relatively high requirements for their living environment. If the environment is not suitable, the temperature control is improper, or there is a lack of entertainment facilities, it may cause hamsters to become depressed or sick.
Improper Diet: Hamsters need a balanced diet. Excessive consumption of high-protein foods, as well as human foods that are high in sugar and salt, can have a serious impact on their health.
Accidental Injuries: Hamsters may die due to accidental situations such as running away, being pinched by a door, or falling.
Cannibalism: Hamsters are solitary animals. Keeping them in the same cage is likely to lead to fights and even death.
