What will happen if you put a inside hamster out side in cold weather?

It is not recommended to put a hamster outside in cold weather. Hamsters are small rodents that are native to warm climates, and they can easily succumb to the cold. The cold can cause a hamster's body temperature to drop, leading to hypothermia and even death. In addition, the cold can cause a hamster's immune system to weaken, making it more susceptible to illness. If you must take your hamster outside, be sure to keep it warm by placing it in a carrier that is lined with a blanket or other soft material. You should also limit the amount of time that your hamster spends outside.
