Thanks everyone for their advice. I've been a bit sick this week so haven't check in.
I had called the pet store last week, and they were very concerned and called a pet behaviour specialist. I followed that advice as much as I could, and I know some people here might not like it, but I have to tell you, it worked! They told me to pick her up and hold her (wearing gloves and continue to hold her even if she bites). I had my husband help me, and we gave her treats and talked to her. I only held her for about five minutes each time. They said to do it for a week, but I can't catch her anymore... she's smart! But, she hasn't tried to bite me, and her behaviour is calmer. It's not that she's scared, but is just calmer. I also gave them treats for other behaviour, so they knew I wasn't just a big grabby giant and both of them are coming around. We have been able to give M'noke scratches, and Kira short pets.
My cage is off the floor, and I always greet them on the same level. Kira was only aggressive while in her cage, not out of it, but she was obsessive with getting out of the room, which has changed. I think she was afraid of something while in the cage (when I picked her up I let her come out first then distracted her with a treat--I didn't want to irritate the fear that was already there). I understand the cage is her sanctuary, but I still need to safely clean it and feed her! Now when I go in the cage she just watches me or moves out of the way. Hopefully this will last. She's also becoming more affectionate, and after holding her I've let her run around and she comes up to me often.
I don't know what this means, but yesterday I was laying on floor (I do this to be less intimidating and give them treats when they come up). They had reached their treat limit, but I was still laying down as I wasn't feeling well. Kira came up to my face and started licking me! I was afraid she was going to bite, but I don't think that was her intention! Has anyone had a chin do this?
I honestly think this helped. Maybe witht he psychology aspect, I told her who was boss? I am just letting them out now. I can't pick her up any more as she just grabs the treats and run, and that's fine. I just lay on the floor and pet them as they come up. I don't mind if theyr'e never super cuddley, but we do need to be friends!
I'll keep you posted, as I'm sure she will change as time goes on!
