Thanks everyone,

I will call the shelter when it's open tomorrow but I know she will not be there --- she does not come to people, and you have to give the SPCA $40 for every cat you give them, so nobody turns stray cats in there unless they are being a nuisance. The city is basically filled with stray cats. Occasionally they are abandoned outside the SPCA so they don't have to pay the fine, so I suppose it's a possiblity she is there. I will leave a message today.

I will have to call the owner today, so I will ask where her home was. I know it was on the other side of the city, and I don't have a vehicle, so I don't know if I'll be able to check there. I don't know the bus routes well, but perhaps one of my friends can take time away from their Christmas shopping to help me.

I kept my door open all night, but of course the people upstairs closed the outside door. So the cat would not be able to get in...Figures.
