Lost cat

My cat Bonnie has been missing since Tuesday. I live 1-10 Anna Rd, Woburn. She is very skittish and afraid of her own shadow. She is an indoor cat. She's mainecoon tan and white, lions cut. Occasionally we let her out on the porch. Last I saw he she was running into to the house. I don't know is she went into a garage or cellar if it was open. Please check if there is an open window in a cellar, shed, garage. She probable will hide. I'm worried sick. Please call Donna 978-987-1366 This is a picture of her and her brother
