Misty is gorgeous. Bless you for taking her in. When I took in rescues, I had some that ate & drank right away, some took a day or two and some took as long as 2 days before they used the litter box and up to almost 4 days before they ate. So here's hoping that Misty will start to eat & drink today or tomorrow.

Prayers on the way that all will turn out well in the end with everyone.
