She may not be able to get back home if someone has picked her up and taken her to a local shelter. Have you visited them all and filled out a lost cat form? Look everywhere in the shelter because sometimes cats and dogs are mixed together ?!?

You may not know Kuhio's story, but she was put to sleep the day after we were at the shelter looking for. They said they didn't have her. They had us look in 1 room. She wasn't there. Turns out she was in the medical clinic. They never even told us about that room. We didn't know to ask. They couldn't find her in their piece of &*#)@% database either -- she was right there all the time.

Have you gone door-to-door with the neighbors? One of them may have taken her in thinking she was a stray.
