So today this cat was found at my work (a library), it had somehow wandered in. I volunteered to take it home and post things on craigslist and such about a found calico cat. I get it home and it is really scared and Charlotte does not really like her. So we leave her alone with some food and water. She is constantly meowing and making noise then all of a sudden she is quiet. We go out into the kitchen to check on her and she is GONE! Nowhere to be found. There is no way she could have gotten out. There are no windows open and all the doors were LOCKED. I dont even know what to do.
