Amy, I've done this. I used to live next door to this bitch who would leave the country and just leave her cat Georgia to fend for herself. She couldn't even go inside. So I took her and she and Kit made friends, and Georgia got very attached to us. Then the girl was pissed because because Georgia didn't want to go back to her apartment. She marched into my apartment and grabbed the cat. I protested, saying she was never home, and she should thank me. "Thank you?" she snarled. "Georgia is MY cat, not yours. What do you think- should I have allowed Georgia into the apartment?
