I started feeding a stray cat about a week and a half ago. She warmed up pretty quickly and now has no interest in going back outside. I haven't taken her to the vet yet because I didn't want to violate her trust by shoving her into a cat carrier before she was ready. She has a tattoo on her lower belly/leg area so i know she's been owned previously and also been spayed. I am planning to take her to the vet tomorrow morning, but I don't know how to react if she has a chip. I am obviously attached to the lady by now. I posted ads on craigslist with pictures of her stating that I found her and if anyone was missing her.. i also registered her on some big website for lost and found animals and haven't heard anything. I've also checked the papers classifieds to see if anyone put out an ad about her. I'm worried that when i take her to the vet, they will scan her and find a chip. I think she should be returned to her rightful owner if they truly lost her, but how do I know that she isn't being returned to a bad owner? She was left out to fend for herself for a reason... either they didn't want her anymore or she wasn't happy where she was. She seems to be quite comfortable here. Is it selfish of me to just want to keep her here with the family that SHE adopted?
