Lucky our hamster

I will start this post out by saying that we have a pet hamster. I got her from work almost 2 years ago. She was part of a handling technique lab for vet students and when they were done she was up for adoption... hence, we have Lucky (Brandon named her!) Well, 2 weeks ago I came home from work and Brandon greeted me at the door as always, but this time he acted a little weird. He immediately told me that he thought Lucky was dead. He said that he went in to check on her around 2 that afternoon and she was sprawled out face down in her food bowl. He picked her up and held her for about 15 minutes before putting her back in her igloo (where she sleeps). He thought she was dead when he picked her up and then when she wasn't he put her back thinking she would surely pass quietly in her igloo. So when I got home and went in to check on her, she was still alive. Honestly, he couldn't believe it because of how little she was moving when he had picked her up earlier. I picked her up and she was so cold to the touch that I held her close for a few minutes. She also had both eyes closed and wouldn't respond to the peanut butter I put on my fingertip. I felt that she could have been suffering so I told Brandon that we should take her to the exotic vet to be euthanized. He wasn't too fond of doing that but said that we should put a heating pad around her. We got one from our neighbor and wrapped her up in a towel inside of the heating pad. After ~30 minutes she slowly began to open one eye. After about an hour in the heating pad she began to crawl a little and about 15 minutes later she had both eyes open and was walking out of the heating pad. We were amazed. We decided to put her back in her cage and place the heating pad underneath it. Then she started doing this weird thing where she would walk a few steps and then fall down, seemingly out of it. Then she would get back up and do it again. Brandon, being the engineer that he is, proceeded to google "my hamster keeps passing out". He found a few message boards of other people describing almost exactly what had been happening to her over the last hour or so. The responses to the messages said that she had most likely been hibernating. What.... hibernating?? It said that sometimes hamsters can go into a state of temporary hibernation, called torpor. We were shocked and happy to say the least. The website said to give her a few hours and she would be back to normal and that's exactly what happened. The next day she was perfectly fine, running in her wheel and everything. We couldn't believe it... and to think that I had actually said that we should have her euthanized, wow! She is still doing fine now. Crazy, huh?
