In the mid-'80's, shortly after I was diagnosed with my lung disease my then husband decided we were going to visit our daughters in Louisiana and Florida; we live in W.C. Iowa. Our son, Steve, had a hamster and we didn't know what to do with it. My sister-in-law told me to put it in the freezer as they will hibernate when cold. So, this we did, all the while Steve telling us we were killing his hamster.
Steve and I worried about that hamster the entire 2 weeks we were gone! I was so afraid that we'd find a frozen hamster when we got home. After 2 weeks we finally were back and we were all standing in front of the freezer anxious to see what had happened. I slowly opened the freezer door and low and behold there was that hamster sitting up looking at us! He immediately walked over to me and up my arm.
There wasn't any need to fear. He had corn, green beans, and carrots to eat, which he did. He chewed into all the packages of vegetables! Of course, he had water since, at that time, we had to defrost our freezers. That little devil never seemed worst for wear! He was a happy, healthy little boy for 2 years.
The next hamster we took with us in an aquarium though. Corky had a lot of fun traveling with us!
