Oh no! Is she still being nasty? Lacey this is starting to not look so good. Do you think its getting any better? You have done everything right and very slow. I'm sure hoping that Ms. Kahlua is not going to be one of those kitties that needs to be alone.
Have you thought about medicating her? You may need to just to calm her down and get everyone on track.

My poor Mowg and Zelda! Bless your hearts. You two have been so good and along comes this nasty girl!!! Shame on her! Maybe we know why she got kicked out of her previous home, huh Mowgli?
