Well, let me tell you this. I brougt home 3, 6 week old kittens to foster. They were sick. They ran from me so much, meds 2-3x a day didn't help. It's been 6 weeks since they've been here. One got placed, I've just got my two boys. They usually only get near me when they're
1) nipped out
2) being fed
3) wanting to steal my food
4) think I'm asleep
What I do is reserve one canned food I know they absolutely love for "pet time". I pet them & they get to eat. I've worked with them & it's a daily process, but they are improving.
That said, due to the way some cats are raised, like if they weren't socalized as babies, were born to a feral momma, were abused, etc. they are more likely to be a little less social than other kitties. That doesn't mean your kitty doesn't love you. Just means that you will have to work a little more to gain her trust, which is so worthwhile. Trust me, the first time she gladly comes to you your heart will break.
