My cat is missing

Hello I have just moved to Melbourne 2 and half months ago and I have been letting my cat go out side and she has been fine till now. She has been missing for 4 days now. She is not fixed as of I am saving up for it. She is microchipped, I have called the pounds around my area I have asked my neighbours if they have seen her and they haven't and I have put up lost posts for her. I was wondering if this has happened to other people. I have searched around the area aswell and no where to be seen. Would there be a chance that she will come back. I am worried because I have to be out of my house on the 22 second of this month. I just really hope she is ok and that she will come back.

Bump

Hi shaishai,my cat also got out one day and I was frantically looking for him, as it was the first time ever that he was out, but I was told by some friends, that cat have this instinct to return home, so just keep your eyes and ears open to his or her meowing, as that was what my fatboy did, praying for his same return.

I am glad you got ur boy back. How long was he gone for? What are the chances of my cat coming home?
