Missing Cat - Orange Tabby, Ellie

Hi! My orange tabby cat, Ellie, went missing a few days ago and hasn’t returned home yet. We’ve posted to multiple social media pages, checked local shelters, searched through the neighborhood, put up signs, etc. Hoping by posting here it can spread the word further. She is 6 years old and is timid towards new people and other animals. We live in the Atlantic and San Pablo area. If you’ve seen her or found her please let me know! I appreciate everyone’s help and support.
