Our cat is fine- but we had quite a scare. We hadn't seen her throughout the night and started searching for her this morning. She is totally indoors- we do not let her outside. After several minutes of searching I was in our office area and could hear her meowing. I thought she was in the garage, just on the other side of the wall. My wife then runs in and opens her safe (RSC) that she keeps her scrapbooks in. Out waltzed the cat. Apparently while my wife was preparing to go on a scrapbook retreat this weekend she had accessed her safe (let's just call it that for expediency) and while doing so the curiosity got the better of the cat and she silently slunk into the safe. My wife closed it up while it was still light outside. So our poor cat spent the night in the safe. She seems to be none the worse for wear, but that brings me to my question. Is our safe airtight? If so, how much air is in there? We are quite fortunate that the cat heard us calling and we heard her. I was standing right next to the safe hearing her meow and never thought she would be IN the safe. I thought I was hearing her through the wall in the garage. I guess she's got 8 lives now.
