[Highland Park] Missing Cat

Hello all... After waiting a few days to see if she returned on her own, I am now putting out an APB on my missing cat. She is a large white fluffly, medium haired cat with one blue eye and one green eye and she has a very light orange/brownish "smudge" on the top of her head. She is not wearing a collar - I found it on the floor! But if you spot her, please please please let me know! She was last seen in our house on the corner of Jackson and Negley but she is absolutely determined about getting out and she is very stealth about it! Thank you Tracy Thurman 412-404-8412
