AC was found on the streets a little over a month ago. The woman who found her was unable to keep her because her cat was very aggressive towards AC. AC then came to my house as a foster. I had her for a week and kept her separated from my cats. During this time she was very skittish, but would let me pet her on occasion. AC has now been adopted by an older couple that has one other cat (KT 7 years old). The two cats at the moment ignore one another, mostly because AC stays upstairs and KT stays down. The problem is AC after being with this couple for a month is still very scary. She will approach them and meow, but when they go to pet her she runs for her life. Every few days she will allow them to pet her, but most of the time she hides. She will come out to play with her feather toy, but again if they try to approach her while playing she will hide. AC is the sweetest little girl and she seems to want to be petted, she will meow, rub her head on doors and corners, and roll around, but when you get close she is gone. Does anyone have any advice on how to win this sweet girl over?
