We're back. They did an X-ray and some bloodwork. The X-ray didn't show anything weird (I was worried she swallowed something) and her bloodwork was normal. I couldn't bear to leave her there so I waited while they did it. She had a 102 temp, so I got an antibiotic (Clavamox) and an anti-inflammatory (metronidazole). On the X-ray there was an enlarged area of her large intestine that the vet said looked like gas.

So we really don't know what is wrong, but she did eat 5-6 Temptations treats after we got home. If she isn't better (still vomiting) tomorrow we'll have to do the barium thing.

I think I'm going to put her in one of the bedrooms with her own litterbox and food/water and see if she eats/poops.
