Thank you all so much!
Miss Kitty's bloodwork was completely normal, but we are sending out more blood to check for pancreatitis.
The vet thought that she either could have gotten a tiny bit of Miralax, or she developed pancreatitis.
She is so skinny now, she lost another half pound since last week.
She was a little dehydrated, so she received subcutaneous fluids, along with an anti-nausea injection.
I will treat her at home with anti-diarrhea meds and more anti-nausea pills.
She ate a little and kept it down which made me very happy.
