I'm new to the group and need advice. I took in a 1yo female feral cat that had been fostered by someone for three months and could no longer foster. I was under the impression she was a stray, not feral. I have no experience with feral cats and didn't realize what I was in for, honestly. But now there's a wild and terrified creature in my house and I want to do right by her. I've had her 3 mo. She has slowly moved from being totally hidden in a spare room to spending most of her time beneath the living room sofa. She has been creeping out at night to eat and use the litter box. But recently she has started pooping under the sofa occasionally.. I have three other cats. They've had some encounters and I suspect the feral girl is afraid of them. What do I do now? How long do I let her stay under the sofa? What is the best thing for her? I talk to her, give her treats. I've tried to get her out but I don't want to do more harm than good. She is not vicious. Hisses but doesn't try to bite or scratch.
