We rescued Sage around 7 years ago, and she still won’t come out when strangers are around. Nope. Only my wife and I get to see her as we are the only ones she trusts.
Right now it’s tough because she has tI stay at the new home, and we aren’t licing there yet. I go there daily to feed and give her some attention.
They call her, the ghost cat...because nobody else believes she exists...
