I knew she would be in danger from people because she is social to humans, but I didn't realize how much. And I didn't think about her not being accepted into the colony, though I should have. We are more concerned about you than Leila at this point, but your main concern is the cat.

I believe by trannies, the poster meant tranquilizers. I can't remember if you've tried those. Given Leila's personality, you may have to go for something heavier than Prozac, something like Buspar. Although then you will have a zombie on your hands part of the time.
