My mom put out a notice to the neighborhood website that my cat is missing, so far 2 neighbors will be on a look out for it.
This iis why indoor cats are better
Actually my cats IS an indoor cat.
There is a possibility, as I said before that she was scared of the sounds in the second floor (where she hangs around the most) and ran downstairs. Since large objects were being moved, the front door was left open, she may have ran out there in the attempt to run away from the loud sounds.
Adding the fact that she's an indoor cat, she won't know her way home.
