Jen, you cannot be everything to every cat. Some of them will remain feral regardless of what you do. Mopsy, I have had for 6 months, as an indoor cat and she is just now beginning to accept all of the others without going into a fighting mode. Also, my Blue Czarina is getting more aloof. She does not like to be picked up, as well as my other blue cat, Puma. Czarina usually sleeps in the basement by herself. She doesn't eat with the others , but prefers to eat during sleep time for the others. I suppose that if I had not had her from birth she would also be incurably feral. So, don't worry about your feral kitten, just do what you can, and expect that she may have a "feral personality". If she does, that is OK, as long as she is comfortable living with you and the others.
