My hamster was playing with the wheel last night. When feeding this morning, I found her lying motionless in her sleeping bag, her eyes open, her limbs open and her body stiff and cold.

Hypothermia, it is estimated that your food protein is insufficient and the nutrition is unbalanced. It's hot and cold now, so it's easy to be cold to shock after running. Don't be afraid to feed too much in winter. She needs to thicken her fat for the winter to resist all kinds of diseases. The most common ones in winter are pseudo-hibernation, hypothermia, cold and psychological wet tail syndrome caused by environment. Looking at it every day, giving more food in winter is also for her habit, and she will go to the nest herself. Almost all of them are eaten in a room full of food. Only in this way can she spend the winter safely. If she doesn't store enough food, she will feel anxious and panic, which will lead to wet tail syndrome. Wet tail syndrome is not only caused by diarrhea, but also by mental illness. Remember this! If you encounter hypothermia again, you should warm her up that day. It is best to start from the abdomen, which is slightly higher than the human body temperature. You can also use your own hands. Generally, it takes less than 10 minutes to wake up slowly and exercise a little. At this time, you should feed warm glucose water and eat foods with higher nutrition but less water. By the way, my family Shi has been in this situation twice and is still alive and kicking.
