<human>: I have about a 1.5 year old house cat who has lived indoors her whole life. She has escaped into the great outdoors. I'd really appreciate any advice you can offer on what I can do to help her find its way back home :/ 

I came home around 5 am to my front door being wide open. Apparently my roommate neglected to lock the door when he got in around midnight and it had blown open. The cat was nowhere to be found. I looked outside in the frigid weather for about a half hour with no success. Since then I have placed her litter box, food, and a laundry basket she likes to sleep in with a rug she likes on the front porch. I have looked around the neighborhood three times today for maybe an hour and a half total. 

I'm having no luck and I know it hasn't been long but naturally I am getting worried :/ she is hardly acclimated to such cold weather... She's never had to get her own food before but cats are pretty resourceful....

Can you give me a shortened version of the text?
<bot>: housecat is missing for a day now and I'd like some advice on how I can coax her/help her find her way back to the house.
