First of all, congrats on your new baby, she's a cutie. Probably a very scared cutie, but still, as everyone has said, a little time and she will come around, when Sprocket first came to us all he did was cry, they don't understand, even though their old home wasn't the best, it was all they knew. One thing that worked for us, and your baby doesn't look too large, is the sling, make up a sling, just like the kind you would have for a reg baby, we used an old sheet and keep her close to you, so she can feel your heart beat, your warmth, YOU. That and keep her on a regular potty schedule, she drinks water, sees the vet. The rest will come, she will not starve herself. Though I personally am a chicken when it comes to the "who blinks first" game and give in to anything to make Sprocket eat, ie: it was the chicken baby food.
I know, I know but those big puppy eyes. I'm such a wimp
, that's why it says personal slave. LOL
