Lost & Found Cats in Antioch

She has no collar on right now

She's an indoor cat only. She's never been outside before. She's 2 years old. Russian Blue, all gray cat with a cut right ear. She is microchipped and registered but I'm scared, because of her cut ear, people will think she's a stray. She does not have a collar on.

He his a black & white short hair domestic cat. There is a small white patch in the black in the middle if his back
