I lost my cat!


My awesome white, pregnant, beautiful, loyal, cat. I always let her go outside. She loves the forest. On July Fourth I went out with some friends. I came back at 10:00.
I went to go feed KitKat and she wasn't there. I thought "oh, she must be taking a stroll around the Neighborhood.
It is Monday July 7th and there is no sign of KitKat. I have now gone into an EXTREME depression. I keep leaving food out hoping that she might come back. I need my awesome cat back! I have these dreams about her Running to Me.
But Then she just falls over flat. I try to stay up at night so I don't have to have any awful nightmares
Where IS MY CAT?!?!?!
Are there any ways to find her other than:
MAking posters
Asking people etc. I need some effective Ways.
