Oh my goodness! I am new here and just saw your thread. I certainly hope Freckles comes out of this!
My little Murphy Brown gave me a scare the other day...She was vomiting through the night, and in the morning was shaking, very lethargic and breathing very heavy and labored... I rushed her to the vet, they took xrays and she has friggin' pneumonia!
The poor thing aspirated on her vomit. They gave her 2 injections of antibiotics and sent her home with me with a 14 day course also.
Anyways, I know how scary it is, and I am praying for you and Freckles!
