Don't give up. Just keep searching and putting up the posters, canvassing the area and calling her name. I know what you are going through. A few years ago our cockatoo escaped. We were very lucky that someone found her. She took shelter on a balcony. If not for the posters, they never would have contacted us.

Do you have two cats? If you have a cat carrier, put the second cat in it and take him/her with you. If he meows, as a lot of cats do in carriers, the missing cat might recognize it. Just a thought.

Someone may have found her already but with no chip, they may think she doesn't belong to anyone. You should take posters to the local veterinarians too in case someone finds her.

Please, everyone, even if your cat is a housecat, they should be chipped and registered with ANIS, the national animal registry. This really does help reunite pets with their owners.

Keeping my thumbs pressed for you.
