Our dining room used to be the living room before an addition was built onto the house. When they did that, they boarded up the fireplace (I don't know why, I just know it was done). We keep Princess Purty Turtle's tank on the hearth cos it means she can see us all day and since it's boarded up there's no draft to bother her or anything. A few days ago, I started hearing some noises from that direction, but I thought she was just being frisky and climbing on the paving stone in her tank and junk. But now there are noises coming from that direction that are DECIDEDLY NOT TURTLE RELATED NOISES and I think there might be something living in the fireplace, so I'm kind of freaking out.
