If you haven't already, start force feeding her, and get her in to the vet.

Use canned foor, put a little on your finger and insist it goes IN the mouth. Then hold the head with nose to ceiling and gently stroke to get her to swallow.

At the vet, they will give her some subq fluids. If she is not eating, she will dehydrate. This will also help her get back into eating.

Let us know what is happening!
