Hamsters are relatively resistant to cold and have a certain hibernation ability. However, compared with the "professional hibernators" such as snakes, bears, and frogs, the hibernation ability of hamsters is much inferior. Generally, animals with the habit of hibernation will systematically and deliberately accumulate a large amount of energy before winter to get through the hibernation smoothly. But the hibernation of hamsters is more like a helpless gamble. They usually don't make any preparations, so the hibernation of hamsters is extremely dangerous. A little carelessness may cost them their lives. Therefore, the hibernation of hamsters is also called "false hibernation".
The primary condition for hamsters to enter hibernation is that the environmental temperature drops to a certain degree. But not all hamsters will enter hibernation under low - temperature conditions. Only some hamsters will enter the hibernation state at low temperatures, and they may die of low body temperature during hibernation.
In addition, in addition to being affected by genetic factors, "light" is also a very important factor in whether hamsters can hibernate. Generally speaking, under the same temperature conditions, if the light intensity is weak or the lighting time is short, hamsters are more likely to enter the hibernation state. Overall, the harsher the environment, the easier it is for hamsters to hibernate.
However, the living environment and conditions of pet hamsters are relatively good. Pet owners will ensure that the environment they live in is warm and provide them with sufficient food and water. So pet hamsters basically will not enter the hibernation state.
