I know how scary it is for you. Please know that she is in my thoughts today. Hope all goes well for her, I'm sure it will. Please upate when she gets home. I do have a piece of advice I learned when my girls got spayed. Don't pick her up under her arms so that her belly stretches. Pick her up kind of under the butt and chest.
Bless her and keep her safe.
She'll be home before you know it.
