I noticed two things with my mom’s reformed feral. 1) He just twitches the tip of his tail when he gets over stimulated. I thought his attacks were without warning until I noticed this! 2) He learned from the other domesticated cats. So a friendly well socialized cat (from wee kittenhood) may be your best chance for her! He learned to play a bit, sit quietly for treats & to cuddle from my 2 kitties. You might need a bridge cat or two to tame her. He never got over his over stimulation bite. I just warn people to watch the tip of his tail when you pet him.
