I am sorry Zoe is causing you to worry, I hope she comes around really soon and is a wonderful mother to the babies. Missys never had babies so I've never experienced this, I am of no help.
You've recieved great advice already, hopefully more breeders will see this thread and give you some advice. Did you also post this in the breeder section?
Good luck and keep us posted on her and her babies.
