Sorry I didn't update sooner....work has been crazy today!
Halo is much better. After the enema yesterday, she ate a little boiled chicken for me last night. This morning she was much perker. She had rice & chicken for breakfast. I checked on her at noon, and no more vomitting. Vet is going to do another blood test tomorrow, but I think she's on the road to recover now; just don't know what she's recovering from.
Thanks for all your thoughts & prayers.
