Three days ago, on Wednesday evening, our hamster, Moonlight, got away from us. Normally when this happens we know where she is and/or she comes back where we can get her, but this time we could not locate her and she did not show up within a few minutes. We soon came to the conclusion that she must have made her way into the vents so we set out some food and water in a couple of places where she might get to them (such as the cool air return in the top of the downstairs hallway). Unfortunately after 24 hours none of the food or water stores had been touched and we were beginning to get worried. Our only consolation was that we were still occasionally hearing scratching noises from time to time suggesting that she was still alive.
Last night after Laura and I got home from our date Laura called me down as she heard Moonlight at close range in one of the basement walls near another cold air return. I took off the cover but there was no Moonlight. We decided that she must not be in the vents but in the walls themselves. We went into the spare bedroom and cut a hole into the wall where we heard her. She was not in the place where we cut, but we continued to hear her. She would begin climbing the walls every time we called her name. When we were confident about where she was located we finally performed the rescue operation (at 11:00 pm):
After two days of being trapped in the walls we had our Moonlight back. She was happy to see us and very happy to start drinking some water.
